PSA PA10 .308 Bolt Catch

The AR10 platform does not enjoy a common design between manufacturers, like the AR15.    As a result, there can and will be subtle differences in the parts kits of various manufacturers.  Some parts, like the fire control group, are shared with the AR15 platform to preserve the options for upgrading.  For best results, we recommend only using PSA PA10 parts with our uppers and lower receivers.  We do not recommend using other manufacturers parts in our products.

What is the difference between this bolt catch and the 508014 catch assy.? Is there a difference between these 2 catches and the catch in the PA 10 upgrade kit?

BEST ANSWER: There are two types of AR10 cut lower receivers, AR-10A and AR-10B. Bolt catch 503661 works in the AR-10B version while the other bolt catch is designed for the AR-10A version. Do a google search on these items and you will see the difference.

Works Great
I bought this bolt catch to replace the catch that came in an AR-Stoner AR-10 LPK I bought some time ago. The Stoner catch was too short to catch my magpul magazine. This one works great.

Worth the wait.
After replacing the generation one catch with the new catch, everything operated as it should. It was frustrating to have a gun that would not stay open after the last shot, but it would still work. Life is good.

Bolt Catch Crisis
I ordered a PA10 lower and it arrived with the wrong bolt catch installed. PSA said they would send a replacement, but the same bolt catch, PN 482650, was sent to me. Sent pictures to PSA and they told me that what I received was for an AR15. I also ordered PN 503661 It was in stock and I was tired of waiting. It arrived, but it is the same as the 482650. Now, I have 3 bolt catches supposedly for the PA10, but none are correct.

Failure of bolt catch to lock bolt back.
I have built a PA10 and a PA65 and neither of the bolt catches work. The bolt catches hit the upper. Therefore, they do not lock open on the last round or manually.

Works great, shipping was too high
The bolt catch itself worked perfectly. If you own a pa10 upper you will need this bolt catch. Don't waste your time trying to make another brand work. It wont. I ordered two, one for a .308 and one for a 6.5 Creedmor, both worked great.
My only complaint was the ridiculous shipping charges PDA charges for parts.

Did not work with PSA AR10 Gen 1 and PSA 6.5 Upper
I built up a AR 10 in 6.5 Creedmore with a PSA upper and a Gen 1 PSA AR10 lower. This bolt hold open will not work. When I emailed PSA, they wanted me to send the entire rifle back for review. I don't see that happening since I didn't buy a complete rifle from PSA.
I suspect the bolt hold open doesn't work with the gen 1 combination with 6.5.
Bummer, I'm out the money and don't have a solution to go with now.

After other bolt catches failed, this one worked!!!
Was having issues with my PSA Gen 2 lower, and a non-PSA bolt catch not coming up far enough to catch the bolt every time. I wrote PSA and told them my issue, and without hesitation they sent me this PSA bolt catch. Installed it, and it works like a charm! I highly recommend using only PSA parts on your PSA lowers, as it will save you time and hassle!

PA10 Bolt .308 catch
Installed PA10 .308 Bolt catch on PSA Gen II lower...catch does not hold DPMS bolt back in PSA gen II upper securely. When the catch does engage slight bump to weapon causes bolt locked to the rear to release and slam forward. Tried to replace PSA bolt catch with DPMS bolt catch bolt catch will not function. Suggestions?
