The PSA PA10 .308 Upgrade kit includes the bolt catch, mag catch, takedown pin and pivot pin.


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 other lower parts kit fit psa gen 2 lower? Psa is good company but the stock on 308 is very very limited and not restocked often.

Any chance you will get this in any time soon?
Jesse on Jan 21, 2019
BEST ANSWER: It's a must have for the pa10. Nothing else will fit.
Is this all that is needed to convert the AR15 lower build kit for use in the PA10?
Jon W on Apr 18, 2018
BEST ANSWER: This is the kit. Along with the .308 buffer. Need both.
Does this include springs, etc.?
Hotkman on Sep 8, 2018
BEST ANSWER: No, just the 4 parts shown in the photos. You can take a standard AR15 LPK and combine it with the parts in this kit to complete your PA10.
Will this complete the 308 lower with my ar 15 kit?

PSA PA10 Upgrade Kit
This is a must-have kit if you purchase the PSA PA10 lower. Pins are specific to the PSA platform and the DPMS pattern kits will NOT work. Additionally, the bolt catch from PSA is sharper and more exact for catching the bolt on the last round. I prefer the PSA bolt catch over any others I have tried. PSA does charge more than necessary for shipping this product, as they do on all their other small parts.

The person who pulls parts could use some help. I had the wrong parts shipped out a few times. Overall I am satisfied with all my parts for my ar10 build.

I would recommend it. Would be nice to see it included in a kit with the bare lower reciever.

I waited months for this product to be back in stock for my psa 6.5 creedmoor. No other bolt catch fit the lower receiver and when I finally installed the part it failed to hold the bolt open. The upper milling will not allow the bolt to stay open. Very disappointed

about time you put this together
This is just what the doctor ordered. You get the parts that are specific to the AR-10 Gen2 lower without the need to by the other stuff that you maybe customizing. Thanks~Ray

Seems to work well. Pivot pin could be a little longer.
Everything you need to upgrade from any 15 LPK. Cheaper to buy the kit than individual parts.

Magazine Catch
Bought this to "upgrade" a standard LPK to finish my PA-10 Lower, however, upon comparing the magazine catch from multiple mil-spec LPKs from other manufacturers. The mag catch is the same. So I'm not sure why they are selling this kit with a mag catch. I emailed PSA support asking if they were supposed to be longer and uploaded picture and they said: "The parts you have are the correct magazine release."
Same size a other mil-spec catches

Mag Catch "Hairline" Difference in Lengths (with Pics)!
Called PSA CS today with respect to my PA10 upgrade kit which includes a PA10 Mag Catch. After looking at it last night, I was convinced I had received an AR15 mag catch as many of the neg reviews here stated. Upon conversing with CS and not getting any better answer than it is a "harline" longer. I took one more look at an AR15 and the PA10 mag catches. It is INDEED a hairline longer. How much longer, CS could not tell me and I did not have my fila gauges home.

I asked about the length difference because I'm an engineer and at first glance and initial measurements with a caliber I could not tell the difference. That, of course, if because I was not expecting much a minuscule difference between the two. Of course the CS agent mocked me, because I have degrees in engineering and could not tell the difference...

With all that being said, PSA should inform their customers what the difference in length is. We can then decide if we want to purchase this part or purchase a part from another manufacturer that is longer (two manufacturers that I know of currently make longer mag catches). I hope this helps you all in the future. I know it would have been a great benefit to me and would have saved me a mocking from PSA.

Why the four star rating then, well the kit is 75% perfect. I'll pick up a longer Mag Catch elsewhere. Either way, this kit is cheaper than buying the components individually and cheaper than an entire PA10 LPK. So I would definitely recommend this to a friend and simply inform them of the mag catch length differences.

Quality, same as most Palmetto. These are proprietary parts for lower, so it would be awesome if they had a supply, along with the lower!
You have to have this to finish a PA lower.
