If you're counting grams that hard, think of it as paying extra for a right side lightening slot .

That's a Seekins Precision. I have one because of some other neat features, but the looks of it are starting to grow fugly to me. The screw is just a soft tip set screw (followed by a locking screw) that you can get at a Fastenal or online at http://www.mcmaster.com/#set-screws/=xxshoe. One pass with drill press and a tap and you can replicate it in pretty much any lower.

3-4 yards. Same bench, same rifle, same backstop that I've used a dozen times...I just set the tripod 3 inches too high. I had just gotten off a cross-country red-eye flight the day before and was scrambling to get setup and test a few new changes to my press and OAL before a big 3 day match. Y'all know the saying: Haste makes for a new post in "Match Screwups".

I went full derp on billet everything building my 3gun rig. If I had to do it all over again, I would have just found a forged slickside upper and milspec lower with a good fit and stuffed them will all the same parts on my current rifle. It probably would have saved me $300 or so and been about 1/2 a pound lighter. There are plenty of billet upper and lower sets that have poor fit. If you're starting from scratch, just mate a few together to get a tight set. Also, the tensioning screw on many billet and non-billet uppers will take out the bulk of any vertical play. Any decent machine shop could add one to the lower of you chooing. I.E. The green set screw pushes against the upper, just under the rear takedown pin:

LaRue here.

Try with 2 more targets or spread the outer ones to where the outer vdrill targets would be. Maybe the small transitions aren't giving you enough of a mental obstacle to push your trigger finger.

Nice insurance, UFO. These crappy boresighters are about ~$10 on Ebay. I think I'm going to use one for myself and everyone else who shoots through the chrony and have them verify aim against a piece of paper between the screen rods. I just hate packing and hauling more shooting gear that's not actually guns or ammo.

Thanks for the laughs, guys! Chrony has a replacement/whoops program, but it was actually cheaper for me to buy a new F1 on Amazon. I was aiming at a target when I blew up the first one. Now I think I'll load a few extra "burners" for velocity testing and shoot for accuracy without the chrony (obvious now, I know).

Just a suggestion- have your kid start out with a bone stock shelf AR and let him upgrade parts as his style/performance demands. It's not a matter of "deserving", I just think he might be ahead of the curve in a few years if he learns what the difference between milspec and "gofast" parts are by experience. It's like having a junior kart racer work up the ranks from a Briggs and Stratton engine vs. handing him the keys to a Ferrari when he turns 16.

I stopped using a can on the AR- the Lmos worked ok with my gas turned almost all the way shut (1 or 2 clicks open), but it just got so dirty from casual shooting I relegated suppressed shots to the bolt guns.

Unless the stage is mostly skinny sammies, at 100 yards and under I find that field of view trumps any benefit of magnification. Is it magnification that's pushing you to switch divisions, or magazine restrictions? The Burris or SWFA would be my gateway into practical/tacops. I know you've seen some turret issues, but it's been my experience that Burris customer service is amazing when it comes to their products.

We did that too. We had the owner on the phone several times trying to get these triggers to work. It's not operator error when you follow the instructions and it still doesn't work. Out of the dozen triggers we carry, we never have any issues other than these. What's not to love is out of the half dozen we sold, 4 came back. The display trigger wouldn't function after hours of fiddling with it and getting the owner on the phone, and it costs $250. Which is more expensive than any other trigger we carry. I'm glad at least some of you got a decent one. I think you just saved me a month of eating noodles.

+2. I've always been a proponent of slickside uppers, and the side charger has few compromises when deleting those two features.

Flyfishdave, why haven't you tried the 80% and worked up? I'm not saying anything is wrong with your method, I'm just wondering for data's sake.

If the spring pack wasn't available I would have been fine with the stock spring and adjustable block. But it is, so now I'm chasing the mo' better.

I think the screen reads "LOLU".

That's pretty much my same setup. I'm going to try one or two spring rates up and tune up the gas to lock back the bolt. The lightest spring "feels" laggy, though it does chamber rounds with authority from a locked bolt. I don't think I can outshoot this current setup with my splits, but I feel that there has been some unidentified compromise in tuning with the lightest spring. I only have about 400 rounds with it so far though. No malfunctions but I feel that it could be better.

Does the SCS come with multiple springs now, or do you have the spring pack? Adjust gas for your ammo and see if your bolt locks back on an empty mag. If it doesn't, try the next lighter spring or increase your gas volume a bit. That's just how I tuned it for minimal gas, but there are plenty of "intermediate" tuning options that may work better for you.

It was probably an older MGM though I can't be sure. It had the spinner plates bolted onto the center section and there were no obvious lateral adjustments - i.e. bearing preload nuts or whatnot. It was lubed and tested prior to the match. The weird thing was that it spun easily by hand with no grittiness, and 2 bulkpack birdshot loads got it over for most shooters that didn't bonus it. It was just the nature of that beast to laugh off slugs for the match.

They were tight and were checked and re-checked many times throughout the match (both by schedule, and by shooter request). Squads were just speculating.

The big 2 day "state" match was last weekend, and there were spinners galore. My first stage had a similar setup as my first post- a shotgun stage (after a rifle string) that began with slugs on steel torsos at 40 yards, a 30 second bonus slug spinner (60 second penalty if not spun by the end of the stage), followed by 20 or so KO steel and aerial clays. The first 4 guys before me didn't get the spinner over with slugs. I loaded up 2 rio low recoil for the plate, and 2 Rem Slugger full velocity 1oz green shells for the spinner. Instead of going prone, I used a vision barrier for support. I sent the 2 rio to the plate with no issues. The first 1oz slug missed the lower spinner plate high and left. I took a breath, got my sight picture, and sent the second slugger dead center into the bottom plate- straight center punched it! The bottom plate swung back about a foot, and that was it. My mind completely blanked as visions of youtube spinners whirling around dissolved into white noise. I began reaching for another slug but decided against it since I had already burned the backup slug in the tube and had birdshot in the chamber (I was shooting factory, so my shot count was critical). I completed the rest of the stage a little frantically but clean, and ran up to the spinner and got it over in 2 (pocket loadout) birdshot loads like the last time. There were quite a few shooters that arrived fresh from their recovery from Ironman, and there were plenty of grumbles from that crowd about how that particular spinner was sticky/loose/possessed. Overall ~23 of 93 shooters got the bonus. 14 of the top 15 got it over. I was ROing a different stage, and when I found some down time I watched the pro/semi-pro squads shoot that bonus spinner. No one I saw got it over in 2 slugs. 3 was the minimum. I have no idea what they were using for loads. Even with misses and light hits, they were all committed to the bonus where I gave up and started running to complete the rest of the stage. I think I'm going to get a third taccom duelin' duces (holds 8) anyway, so when stages start with a slug bonus I can load a tube with an adequate number of slugs to ensure the bonus, then clear them and load the full course of birdshot loads as I move from the slug box.

I'm going to be in the garage messing with my 930 in an hour or so. I'll get you a measurement if I can. Did yours melt via shooting?
