Hello all,

 

I have a PSA PA10 gen 2 20 barrel and I was wondering what I can do to make it more accurate? Im a bit of a noobie to the AR platform, so Im still learning a lot of the basics. I dont reload anymore but have thought about getting back into it. I know load is a huge accuracy factor, but for now Ive found the federal 175gr BTHP shoot the best. Still Im only getting 3.5 at 100yards AFTER the barrel warms up. When the barrel is cold the first 2 shots will be random 8-14 off center usually high left (The rifle is benched on a lead sled so I dont think Im pulling) I know cold/clean bore shots are always a bit different, but does this seem a little much? The only thing I did was put an adjustable gas block on it because of over gas issues... Any accuracy ideas would appreciated.

 

Also does anyone know if BCM makes 308 barrels? This is for a different project and Im looking for barrel recommendations in this caliber.

Thanks!!!!!!

The first thing I would do is lap the barrel opening on the AR10 upper.

Something's not right if you're getting those kinds of groups.

 

Are you using federal gold match factory loads with the 175gr match kings?

If I had one tossing my first shots 12" on a cold bore it would be going straight back to the supplier guessing this is a complete upper and not a self build. An inch and a half maybe but nothing more and that's only the FIRST shot. If it is a self build then there are several places to look.

 

3.5" is not unusual just picking one load off the shelf if you are using factory ammunition. I would branch out and try three or four more. I routinely shoot five different kinds of factory on a 308 for evaluation initially.

 

I don't use BCM bar reels but I know some good barrel guys for you..lol

This review is making me reconsider a PA10 for my .308 rifle. You mentioned you have a PSA 20" barrel. Did you purchase just the barrel, a complete upper or a whole rifle?

Thanks guys.

 

I purchased this as a complete rifle from PSA. The cost between the 18 inch and 20 inch was very little... I sent the rifle back to PSA with targets and a detailed explanation of what was happening. I just got it back with a new barrel and so far as Im breaking it in its shooting much better. Its a bit early to tell for sure as Im only 20 rounds in and Im cleaning the barrel between each shot, but I think the problem may be solved... Thanks for the help!!

Nice to hear that they took care of it for you.

 

I got my 20" PA10 as a complete upper, and I bought their complete lower separately, and it has been flawless. MOA or better with good ammo, and the whole thing cost me under $1,200 with the optic, mount, larue MBT trigger, and all the magpul stuff I put on there.

Do iiit! You know you want to!

 

I can recommend at least the Loaded model with the NM sights, barrel, and 2 stage trigger. I love everything about it, except I did replace my rear iron with the .0595; the .0520 NM rear sight was a touch too small for my aging eyes.
