  1. The Quentin Defense ARQ-15 skelotonized fits your requirements: https://www.quentindefense.com/product/1861/ Quentin makes a lot of receivers for other sellers. I’ve been highly impressed with the quality of equipment made by Quentin.
  2. @kkant - welcome to the forums. But I can't figure out - how is it that you've been thinking about this for 11 years when you joined the forum this morning? Also: https://lmgtfy.app/?q=necroposting
  3. thanks - i'm sure you were very clear and I just have some studying to do in order to understand more of the details, so thanks for the extra details. I've ordered mag springs from both Tubbs and Sprinco just to compare them in actual use. I'll be replacing all of my oldest (approx 10 year) magpul springs. If there's any notable differences in use i'll report back here.
  4. This is great information and specific answer of a 5% difference over time is great. I have some reading to do to understand this better. thanks!
  5. i need some AR magazine springs. For action springs I have had good luck with CS springs from sprinco and flatwire springs from Tubbs. So I checked both of their sites for springs and found both make a 17-7 flatwire magazine spring. I actually like the fact that Tubbs says it *can* hold more rounds in a magazine. I'm thinking that would make it easier to load a full 30 round mag on a closed bolt - something that might be very useful in competition. Sprinco does cryogenic treatment on their flatwire magazine spring and tubbs doesn't. I can't find any definitive information on what exactly the advantages of cryo treatment would be on a magazine spring other than longevity ... but I don't think I could ever load and empty a magazine enough to wear out a regular 17-7 spring. Does anyone know if there are additional advantages (or claimed advantages) of cryo treatment of springs? If cryo treatment would aid in preventing spring fatigue of a constantly compressed mag spring I could see that as an advantage ...
  6. i should have mentioned SanTan as an option - they are right down the street from me and I forgot to add them to my post. Also keep in mind that balance is often much more important than overall weight. A heavier stock will counterbalance the barrel weight and the rifle will be perceived to be lighter. I did some balancing with a rifle my daughter was shooting - she said it was too heavy so I replaced the lightweight stock with a heavy stock (added about 2 lbs to the overall weight) and she was much happier with the "lighter" rifle when, in fact, it was 2 lbs heavier. In fact, saving weight with a lightweight stock will make young shooter feel like the rifle is really heavy because they tend to leverage the weight of the barrel by pulling on the grip rather than the hand guard. Do a quick experiment with your daughter - have her hold/dry fire a rifle with your lightest collapsible stock on it. then switch out the stock with your heaviest stock and ask her which felt lightest.
  7. I noticed that Rosco has a light 3gun barrel on sale for $120: https://www.roscomanufacturing.com/shop/kennel-bargain-bin/kennel-bin-barrels/16-in-3-gun-5-56/ I've never seen a barrel profile like that before, but at 21oz it fits your criteria of "light". And, that profile looks like most of the weight is towards the chamber so it might be perceived lighter. Since it's carbine gas you'd have to work to get the low recoil, but if you get a JP SCS or a VLTOR A5 you could probably get light and low recoil. At $120 and with Rosco's reputation I picked one of those up to try out.
  8. looks like you have a low profile upper receiver and the handguard is for high profile receivers. Troy has a good write up here: https://www.troyind.com/sites/troyind.com/files/rtc-attachments/DPMS_RECEIVERS_COMPARE.pdf another good source here: https://monstrumtactical.com/guides/selecting-a-handguard-for-your-ar10ar308lr308/
  9. the Gibbz side charger is great ... and, if you go with Gibbz you can go ahead and get left hand ejection. Here's a great example of a beautiful Gibbz cerakote (at 7:27) ... this shows a 9mm upper made by Gibbz, but it's similar design to the AR15 upper. other options in that style: Quentin Defense ARQ: https://www.quentindefense.com/product/quentin-defense-arq-15-ar-15-receiver-set-slick-side/ KEArms is southpaw friendly: https://kearms.americommerce.com/ if you want full ambi everything the POF lower is an interesting option.
  10. here's a good video on the topic and it shows holdovers on a target (about minute 4:00)
  11. https://dummybullet.com/12 gauge.html I bought a set that was slightly longer than my normal load so I emailed dummybullet and asked for a specific size and told him the load I use. Bruce made a set for me with exactly the color I wanted with the size exactly matching to my regular shotgun load. Normally I wouldn't worry too much about the size ... but I needed them to exactly match my shell carriers so that I didn't have to adjust the carrier for practice.
  12. hard to beat Rosco or BCM. Rosco makes a lot of the barrels labeled by other manufacturers. I don't know who makes the BCM barrels but they are very nice also. I've used BCM with great results, Rosco will what I buy next. Listen to Aaron (note these are reviews of the entire upper, but the barrels in the first video match your question:
  13. I picked up the cmore C3 in the Memorial day sale and used it yesterday in a black rifle match on a new upper. I had originally planned on using a Gen II-e 1-6 Razor on this rifle but after looking through the C3 and the Razor side by side I decided to use the C3. I'm not a glass snob/expert, but in 30 minutes of comparing my Razor with the C3 right as the sun was going down they both looked the same to me. So on Friday I pulled my razor and zeroed the C3 at 50 yards (ran out of time and couldn't confirm at 200 yards). The dot on the C3 is very crisp - no halo/bloom at all. not as bright as the razor, but bright enough to see red in the AZ sun. I'd compare it to the Kahles that I looked through once. The control is nice - the right amount of friction and off positions in between - just like Razor controls, without a lock. As someone mentioned before I can't see any light on the 2 lowest levels. The reticle is incredible - it was very each to get the holds exactly where they needed to be. Tom Jarret got it right. The (c) copyright engraving in the top right of the reticle seems much too lawyer involvement. but the ranging setup is nice and easy to use The edge of the scope "disappears" as much or more than the razor. 1x looks very red-dot-ish (although the closest targets in the match were about 40 yards so I left it on 6x the entire time) Zoom friction is easy to move - don't have a switchview yet but wasn't a problem since this match is pretty much all long rang Eyebox is great - it seems to be as good as the Gen II-E or Leupold VX-6 FOV - at 6x it seems better than the VX-6 I used before Covid. At 1x it's as good as a red dot Turrets - they are locked - have to pull up hard to get them to move. I prefer the Vortex caps for 3gun, but the turrets on the C3 aren't going to move on accident. Setting the zero was easy - just use a screwdriver to remove them and put them back on. Elevation has a zero stop so you can't dial under. I would have liked 1/4 MOA clicks ... so vortex still has the best controls. I placed higher than I ever have in this match with a brand new rifle and scope (only had about 60 rounds through it the day before the match all from bench). @SinistralRifleman beat me by less than .4% using the Vortex Gen III 1-10. I have to attribute some improvement to the KE-Arms lower with its huge magwell which saved me time on a reload. If Cmore continues to honor the discount code from @TonytheTiger, I can't imagine any need to spend the extra money for most 3 gun matches. I still want a Gen III 1-10 for longer range, but if you are shooting inside 600 yards, this scope really deserves more attention than it gets when it can be had for just over $800. I'd like to see SupersetCA Paul's thoughts on this scope compared to the top of the line scopes
  14. and, for the record, I highly recommend the vltor emod and imod stocks. Quick story about the vltor stocks - a friend of mine carries a rifle for a living and recently used my rifle (with a weighted vltor imod stock) in some of his training. The battery compartments are filled with lead shot and the stock weighs north of 3.5 lbs. A few weeks back he asked me if I had any extra lead shot he could put in his duty rifle. When he came by to pick up the shot he told me why he wanted it. He had been training and his task in some of the exercises was to cover a door (at a low ready position) while the rest of the team finished clearing the building. My rifle with the heavy stock was so much more comfortable in the exercises that he wanted to add weight to his duty stock during building clearing. The balance was much more important than light weight and he felt like it improved how long he could cover the door and improved speed in confined spaces.
  15. To add to @StealthyBlagga's comments we have 2 videos on the Rio Salado youtube channel (https://www.youtube.com/c/RioSalado3Gun) that talk about stock weight. One video that has@Daniel Horner from the 2018 match answering a question from Thomas (who had recently started shooting 3gun) and he gave a lot of great info. (I thought that video was uploaded 2 years ago but couldn't find it so I re-made it this morning.) Also watch Jordan with the www.kearms.com team starting at 4:00
  16. I use the Leupold Multigun w CMR-2 reticle. Zero is at 50/200 yards for my hoser ammo (see below for all the holdovers using today's weather). My gun shoots about 2MOA with hoser ammo and that's good enough for all the long range targets I shoot. when I miss it's usually because of me, not the gun. Ammo differences can make a huge difference in your holdovers ... I attached my hoser load (55g Hornady SP) and a long range load (77g) so you can see the difference. I remember in a class I took from Frank Proctor he was saying as a principle always try to get another point of contact. If you have 2 points of contact, try to get 3, if you have 3 points, get 4. The more you are in contact with stable objects the better.
  17. I really like the brakes I got from https://www.quentindefense.com/ There's a lot of info about the brake here: But you've made me very curious - why in the world would you pin/weld a barrel to be 12.5". you already have to put a stamp on the lower for a 12.5" barrel (unless it's a pistol). But either for a stamped SBR or a pistol, why pin/weld the brake on a 10.5" barrel?
  18. you could adopt this rule into your outlaw ruleset: USPSA Rule 9.5.2.8 In a Multigun match any hit(s) upon the scoring surface of a scoring paper target which can be determined to have been fired from the incorrect firearm for that target shall not be scored and, unless there are scoring hit(s) from the correct firearm, it will be scored as an unengaged target. In the case of steel or frangible targets any hits by the non-specified firearm which result in that target being unavailable for further engagement, the target shall be scored as an unengaged.
  19. This photo is only applicable if you are looking through your primary optic with the rifle turned (that is if you don't have a second sight mounted at 45˚ offset). When you have a 45 offset mount, you zero the second optic while the rifle it turned at 45˚ and then you don't have to adjust your hold because the second optic is zeroed while the rifle is held at an angle. So whenever you turn your rifle 45˚, you hold dead on.
  20. If you are having problems getting these, here's a suggestion: I use SoundGear (https://www.soundgearhearing.com/collections/custom-fit) purchased from Chris Bain at https://www.houseofhearing.com/hearing-protection. Note - if your work/insurance has a hearing protection/aid benefit it might cover some or all of the cost. Chris is a shooter and sponsors SMM3G. When I got mine I had the molds done locally and sent them to Chris via UPS. less than a week later my ear pro showed up in the mail. Been using them for 2+ years now with now problem. A new set of batteries lasts several matches and several practice sessions. I usually change them monthly. Amazon has 60 batteries for $15 which lasted me 2+ years.
  21. I have the SWFA 1-4 and a Razor HD Gen II-E 1-6x. In my opinion the Strike Eagle 1-6 or 1-8 is a step down from the SWFA 1-4. I have a strike 1-6 and I prefer the SWFA 1-4 for 3 gun due to the glass being more clear, much less distorted, and the SWFA has a better eyebox. I can see 535 yard targets better in the 1-4 than I can with the strike 1-6. The Razor is definitely a step up from the SWFA 1-4. I've used a PST and I found the scope to be nearly as good at the Razor ... so much so that I regretted spending the extra $$ for the Razor. To compare I put the PST and the Razor side-by-side and compared what matters most to me for 3gun: eyebox size. The PST was 100% equal to the Razor. I'm not a glass expert at all, but the only place I could tell a difference between the PST and Razor glass clarity was after the sun set and it was getting dark. So, if I were buying a hunting optic and I know that my 400+ elk will only come out in the last 30 seconds of legal hunting time, I'd get the Razor. For 3gun, if I had to do it over again, I'd get the PST. Having said that, I normally use a Leupold VX-6 HD 1-6x. I find the eyebox slightly better and the weight being exactly 7oz better with the only negative being lack of daylight-bright dot in the reticle. Of the other scopes mentioned by others above, I'd give a +1 to the Trijicon 1-8 and the CMORE C3 (with the enos discount). In my opinion the clarity of glass on each of those is on par with the Razor. If you really want 1-8x - that Trijicon is nice and comes VERY highly endorsed by several people I know who consider it an upgrade from the Razor. The Accupower I looked at didn't have any issue with thick reticle ... the center cross is pretty thick at .75 MOA ... but you'd never hold on the center cross at anything > 250 yards ... you'd be down in the .25 MOA stadia lines which would cover ~1 inch at 400 yards. I'm looking at it on Strelok and it looks pretty nice at distance ... I'll attach a snapshot of an AC plate at 480 yards with both an Accupower and a Razor MOA. Based on what I'm seeing and the subtensions, the Vortex Razor has thicker reticle (.5 MOA) than the Accupower, so you may want to confirm what you read about the Trijicon being ridiculously thick since it's half the thickness of the Razor. btw, if you are comparing scopes, I'd highly recommend Strelok pro - you can visualize the reticle before you buy and get your holds based on various bullets and external ballistics.
  22. Here's a quick video from the GoPro so you can see most of the process. edited out about 2 minutes of things that didn't clear the case. I'd call this redneck engineering ... but since the idea came from a brit, I think the proper term is chav engineering. I should point out that I was the only PCC shooter in the squad to go 1-for-1 on every 200 yard target I engaged on this stage
  23. I use the Safariland pouches and they've been solid. http://www.safariland.com/products/holsters-and-gear/gear/pouches-cases-and-holders/competition/magazine/model-773-competition-open-top-magazine-pouch-11183.html#sz=12&start=32 http://www.safariland.com/magazine/model-774-rifle-magazine-pouch-11184.html#start=1 http://www.safariland.com/products/holsters-and-gear/gear/pouches-cases-and-holders/competition/holders/model-086-double---8-shotgun-shell-holder-model_086_8.html#start=1
  24. I've seen a lot of Calvin Elites at our club matches each month. I run one and at least 3 other people in my squad last week at black rifle match had them. I haven't seen any light strikes.
