  1. MPX Killer?

    My understanding is that for the DI 9mm uppers, the mag catch shelf needed to be lowered a bit to keep the feed lips of a Glock mag from interfering with the bolt lugs. I have been told it is also possible to drop a Colt mag low enough to gain compatibility on the DI setups. The upper I had was sold to a friend, who is testing it with an undisclosed lower/mag combo. Under the tech specs it also says it requires a modified upper for reliability. I haven't seen a picture of the barrel extension, but my guess would be that for a Glock mag setup the upper itself might need to have a feed ramp cut in the middle (as opposed to the M4 ramps already cut in most uppers). Tim, any chance we will see a ULW Guard Bolt/Barrel kit?
  2. I'm thinking about getting a new open gun built.

    Glenn at LSI built me an amazing open blaster- it is set up exactly how I want it. He worked with me from beginning to end. 6 months is pretty reasonable for a full custom- some of the other builders mentioned here are 18 months or more. I would second kneelingatlas' suggestion to pick up a used blaster and shoot it to develop your preferences. That way, you have something now while you get a custom built. I personally wouldn't drop the coin on any of the "factory" open guns that are currently available. In my opinion the price is too close to a custom and too far above what it would cost to pick up a used gun. It seems like every week or two there is a thread on somebody's new "factory custom" that has quit at a very low round count.
  3. Charging Handles for AR-15

    Think of an extended CH as a slide racker. It makes unloaded starts and malfunction clearance easier and faster than they would be otherwise. I have the NERD extended ambi handle and it makes it easy to run the bolt from either side. That style is made by Radian (formerly AXTS).
  4. Taccom barrel

    This is hands down my favorite barrel configuration that I have tried! Absolutely worth the money if you like light guns. I have mine set up with a BCM KMR Alpha handguard, which makes the front end feel nearly weightless. It is supremely easy to drive. Anecdotally, I installed the ULW barrel and took it straight to a 6 stage club match without even rezeroing it. I took 1st out of 23 PCC shooters, and 3rd out of 128 overall. The handling is fantastic but the recoil is surprisingly low considering the weight reduction vs my old setup. I believe the shorter barrel will let me get away with an even lighter bolt/buffer combo. Testing that theory is on hold because my red dot took a swan dive onto concrete, but I am excited to get some more rounds down range with it soon.
  5. Quality and Price

    I'll bite, as I purchased a QC10 over the NFA last year. As mentioned, BHO is in the lower. As I live in CA I had been anticipating PCC 10 (which fortunately is on hold, at the moment) and efficient LRBHO seemed like a nice feature. If you are buying an upper and lower, the price difference between the NFA lower and upper with proprietary LRBHO and a QC10 lower/Anderson Sport upper is negligible. Plus I can swap uppers with a Colt based setup and use whatever upper I feel like using without losing that feature. QC10 has sales frequently which help offset some of the difference. Anecdotally it seems that the QC10 positions mags in a slightly better position to feed, as well. I have seen lots of issues with the NFA lowers and extensions. I have seen fewer issues with the QC10 lower, although I have also seen fewer QC10 lowers at matches so it is hard to say that means anything. That said, I prefer the plastic mag catch on the NFA, as it doesn't beat up the notch in the mags the way the QC10 catch does. If you don't care about the features then I agree, why bother with the QC10? It is significantly more expensive. I happen to feel that the features make it a better mousetrap. Not everybody will. If I had to build one on a tight budget and didn't care about LRBHO I wouldn't hesitate to use an NFA or a lower they sell through somebody else. It is much more important, in my opinion, to put the money into a quality barrel and bolt.
  6. Rowdy, for your first point, take a look at HHFs for the 99s. I believe those were before Production division existed, and were obtained by taking Limited HHFs and multiplying them by an arbitrary percent (looks like 95%). Spot checking some of the 13s (most recent) the differential is much, much closer in recent years as Prod guns have developed into DA/SA L10 Minor guns and the talent pool has deepened. For example, 13-07 has a 10.81 HHF for Limited, and a 10.75 HHF in Prod, less than one percent difference. If you look at some of the classifier-ish stages from major matches (Stage 1 of 2014 Nats comes to mind) the top Prod shooter will have a higher HF than the top Limited shooter, or be very, very close to it. As far as my personal experience goes, I don't really shoot a Prod setup, but I spent several months shooting Limited Minor with my standard 40 cal Limited gun a while back. I actually made Master in Limited shooting Minor. For me, it was noticeably easier shooting As with lighter loads, as a lot of the AC, AC, ACs turned into 6As. I was able to get 2As without putting nearly as much emphasis on my grip, and shooting in awkward positions was noticeably easier leaving me free to focus on sight alignment and trigger press. I'll be honest, despite my best efforts I can't shoot a Bill drill any faster in Minor than I can in Major- I believe this is due to my current draw and trigger speed. Out of a Racemaster shooting Major or Minor I have pushed down into the 1.7x range. What I can say is I fail a lot more of those fast Bill drills shooting Major. You have to get your grip perfect and really squeeze the gun to get the major PF gun tracking in the A zone at that speed. Now I don't think minor Vogel would beat major Vogel over the course of a USPSA match, but I think he probably would on a plate rack, or on an average of 5 plate racks. None of the top shooters choose their standard USPSA 40 in Major for three gun. I don't think many (any?) top shooters shoot Major pf ammo in steel challenge outside Open (and even then, I think most shoot reduced loads). So it seems reasonable to me that there is some adjustment for PF. What would you propose for a more reasonable point differential, none? 3.5 per C? At the end of the day, pick the division/PF you like, and shoot it. I think your thoughts on mag capacity are spot on. If you look at 2014 Nats again, high Prod and high L10 are separated by just over 1% in the Combined Overall. I wouldn't be surprised if the top Prod shooter places above top L10 at this year's Nats. Just my thoughts, and I understand some may disagree.
  7. Taccom barrel

    I received my new Taccom ULW barrel tonight and installed it. The weight and balance is amazing! I will finish installing the handguard and shoot a match with it Saturday, then report back.
  8. Setting Up AK47 for Match Use

    Th Red Oktober match from last year was a blast! Here is my build thread and match video from last year's match: If you want to see how it is done watch Samuel Travis' match from last year. He won HOA with a chopped, pinned and welded iron sighted 7.62. I shot Heavy Kalash, so I used irons and 30 round PMags with the Magpul coupler. I used HSGI Taco pouches, which work pretty well, but can snag on the lip of the AK mag. I used the coupler for most stages but most guys I saw were reloading from the belt. I monopodded on one stage and the 30 round mag height was great (I'm 6', 220 lbs, for reference). The ALG AKT is very good for the money. I'm planning on doing some work to my front sight base to get it square and pinning and welding one of the SJC AK Titans to replace the stock AMD65 comp. The big differences in setup for next year depend on if they do a night stage again. IIRC last year's was tossed due to the light not being controlled to provide competitive equity. If they do, I would strongly consider some flash suppression and definitely get some white light on the gun. The guys with good lights and/or dots were ripping through the stage with no issues like it was broad daylight. After 6 or 8 shots my eyes were toast, and I don't think I even cleared half the targets before I timed out. I probably wont get anything fancy, maybe just rig up a handheld Surefire but that light makes the sights stand out on the plates. In terms of safeties and other details, I went with the stock parts for now. They had a lot of cool vendors last year with demo guns, suppressors, parts, etc which might give you a chance to go hands on with some of the other parts you are looking at. It sounds dumb, but I would take whichever of your AKs is most reliable. Lots of guys had gun or mag issues. I liked the light, stamped, and shortened gun I shot because it let me run coupled mags without getting too heavy.
  9. Comp For New Build

    A big plus one for the LSI here. I'm going to have to disagree with my good friend kneelingatlas here. While I appreciated the extremely light weight of the CFD comp TO ME it felt noticeably harsher in the hand than a similarly configured blaster with an LSI comp. After trying both I had Glenn at LSI build me a midlength, steel gripped 9 major with his comp and 3 ports. I'm no Open master but I have had some die hard 38 shooters blown away by how my gun tracks and handles.
  10. SVI Infinity Signature SS Grip

    Tactical Micropockets was the Goldilocks grip for me. I prefer it greatly to the standard or the aggressive. A lot of guys consider blood and scrapes from the aggressive a badge of honor. I prefer to grip my guns so the Tactical seems to be good for that.
  11. Metal grips = Arched housing ?

    No. The metal grips are metal grips. Mainspring housings come in a variety of shapes and sizes. The SV Ergo and maybe the PT Evo both have a more CZ-ish back strap profile. The SV comes with a custom MSH that matches the grip and beavertail. Maybe that is what you are referring to. Either way, they don't match the profile of a standard arched MSH. I do greatly prefer the ZM/Dawson metal MSH on a plastic grip to the plastic MSH. I like the SV Ergo even better.
  12. I agree with you on this point. The difference is we aren't talking about an AR chamber and bolt. There are no locking lugs as these are straight blowback. Also, unlike a standard AR bolt where the firing pin can't reach the primer unless the bolt is in the locked position the blowback ARs will fire out of battery. You could have over 30k psi supported by nothing but the brass. I've seen enough blood on multiple occasions from out of battery ignition that I wouldn't do it. If you want to that's cool but think about who might be to the right of you. For me, as a right handed shooter an OOB incident would likely spit brass at the RO. It might be worth it to you, but personally I'll just get the defective round out and keep shooting.
  13. Gamer AK

    The Red Oktober match allowed any ammo, which was nice. Barring that I would try to use Yugo M67, which, I believe doesn't attract a magnet. As an update, SJC now makes a Titan comp for the AK so I think mine is about to get louder and flatter shooting than ever before.
  14. Romeo 3 mount

    Here is a thread with a few different angles of it: http://forums.brianenos.com/index.php?/topic/244227-9mm-lsi-ss/ I like the Romeo3. I have been using one for PCC where it is perfect. I like it on the Open gun and the brightness seems good. I like it as much as a standard, vertical CMore with the benefit of reliable 9mm ejection and less height over bore, and much better than a 90 degree CMore.
  15. Romeo 3 mount

    I am using the Double Tap RTS2 mount with my Romeo3. The blast shield just needs 2 holes drilled to be able to mount it to clear the extended front profile.
