I was having a hard time picking up my 3 in bright sunlight so switched to an 8. For me, the 8 is perfect for PCC.

I just received my SBR tax stamp. Took 9 months exactly. So far I'm really liking shooting the 10" barrel vs the 16".

I've got two of the Gunpoint lowers and I'm real happy with them. One of them has 15,000 rounds on it with no problems.

Finally got my tax stamp after waiting 9 months, so I got to finish my latest creation. 6 pounds, 2 ounces all up. Gunpoint Colt pattern billet lower VLTOR upper 10" JP barrel 7 1/2" UTG Pro Keymod handguard C-More 8 MOA Railway Spinta bolt Polished CMMG trigger with light JP springs, just under 3 pounds Radian Talon 45 degree ambi safety Radian Raptor ambi charging handle Ergo grip Magpul MOE stock Taccom comp

Primers. I use a milspec LPK with the JP light springs and with CCI I'll get a FTF about once in every 4-500 rounds. Tula/Wolf run 100%. Trigger pull is just under 3 pounds.

I have a CMMG with 14,000 rounds on it and a Spinta with 4,000. No problems with either one. The Spinta cost half of what I paid for the CMMG.

I like the Ergo. Really fits my hand well.

I just measured one that works and compared it to the one that didn't. The one that would double feed was wider.

No loctite on either of mine. 20k rounds later they're both still tight.

Mic the mag lips. With my Metalforms, I had one that was a little wide that would occasionally double feed. Tightened it up in the vice to spec and have not had any problems since.

For your second match you're doing fine. It takes a while to get comfortable running around with a rifle as opposed to a pistol, and movement really is the secret sauce. My number one suggestion would be to practice coming into your positions with the gun up ready to shoot, and break the shot the second you have a good sight picture. Do this left to right AND right to left. Also, get to know how fast you can double tap targets based on distance. Some of your splits on close targets were really slow. You don't always need a great sight picture for the second shot....if it's under 10 yards or so, blaze away!

I've had real good luck with both my JP barrels. I've got one of the new stainless Spinta's that looks great but have not tried it out yet. The chamber is not quite as generous as the JP's, but being stainless, it can be reamed. I played around with different SBR lengths and like the 10" best.

This is from their ad- "The upper and lower receiver are more than 1 inch shorter than a standard AR-15 upper and lower receiver making it more compact and lighter than a standard mil-spec AR-15 design." They show the bolt in the video. It looks....unique.

Looks like the upper, lower, and bolt are all proprietary and not the "standard" sizes that are usually seen. That would limit your upgrade/replacement choices. Good price though.

This. Internal case volumes vary greatly by manufacturer. Different case volumes will vary pressure. If you want precision, I'd start by using same headstamp brass for your testing.

I've done extensive testing with powders in my PCC's and don't really notice any perceived recoil/dot bounce differences in fast powders vs slow powders so have settled on using fast powders for purely economic reasons. It takes me 30% more HS6 to make a given PF vs Titegroup. At one point, I hypothesized that the HS6 might make more gas to work the comp, but in testing I didn't notice a difference.

I have the Radian Talon on both my guns and really like them. You can use it as a 90 or a 45 degree throw. 45 degree is much faster for me. They give you 4 different size levers so you can use the ones that fit you best. https://radianweapons.com/accessories/talon/talon-ambidextrous-safety-selector-4-lever-kit-ar15

I've got 2 of these. 14,000 rounds through one and 4,000 through the other. Been 100% for me, really like them. Right now they're on sale for $179. http://store.avguns.com/9mm-ar/9mm-ar-lower-receivers/gun-point-9mm-ar15-billet-m9-stripped-lower-receiver/

Got to be the ejector. Both my builds had the same issue until I tweaked the ejector just right. Both have been flawless since.

I agree that we really need to be using PCC high hit factors, not Open. Hopefully, this will be implemented soon. As for the classifier system in general, it does a good job of measuring one's ability to stand and shoot classifiers. Sometimes that correlates with one's ability to shoot matches and sometimes it doesn't. I guess it's the best system that we can come up with.

As with any other gun in any other division, it comes down to one thing. Lots of practice. My reloads started out at around 2 seconds. With countless hours of practice, I've got it down to where it's similar to my pistol reloads. Here's video of the classifier I shot last Saturday- El Pres. in 5.03 seconds, good for a 93%. Don't know the time on the reload, but I was happy with it. And I'm gonna keep practicing.

I use these too. Cheap, effective and comfortable.

Both of my JP barrels are .3565" diameter. If I run bullets less than .357" diameter, I get significantly less velocity compared to the same bullet in my YHM barrel which is .3545" diameter. I suspect you lose a little pressure from the bullet not sealing the barrel efficiently and that affects your velocity.

I think this is a universal problem with Colt pattern AR 9's. If anyone has found a solution, I'd love to hear it.

Looks a lot like the JP, but 4 ounces heavier. And more expensive.
