The Gen2 PA10 receivers are functionally compatible with the Gen1 upper receivers, however we recommend matching Gen2 lowers to Gen2 uppers for best appearance.  There are external cosmetic differences when mixing Gen1 and Gen2 upper and lower receivers that some may not find appealing.  Gen1 lowers will be available in the future for those who want a cosmetic match.

I realize that not all uppers fit all lowers... depending upon the brand of the lower. Will this PA10 upper fit a polymer 80 frame..without modifications? Has anyone put this PA10 upper on a Polymer 80 plastic frame?
diesel on May 7, 2018
BEST ANSWER: Also, some of the lower parts in this rifle kit do not fit the Polymer80 lower. You should order the Polymer80 LPK for the lower receiver. I had to. I know, extra money, but it's the only way to get it to work. Most of the lower parts in this rifle kit only work in the PSA lower.
Will this fit on a aero precision m5 308 lower?
Adobo on May 29, 2018
BEST ANSWER: I’ve seen on PSA website where they suggest matching their upper assemblies with a matching PSA lower. Will it work with an AP? Maybe. Would you be better off ordering a PSA lower? Yeah.
Am I correct here? If I purchased this item to build an AR-10, the only missing from the kit is the lower frame, so I could purchase item 516445318 when available and would have everything needed for a functional rifle?

Is this an 80% kit?
Billy D on May 9, 2018
BEST ANSWER: No, this is not an "80% kit" as the modern lingo goes. This is a build kit that is a complete weapon minus the lower receiver which holds the serial number. An 80% kit would be a full set of parts for a weapon which requires some level of machining to finish the main component (which in an AR type rifle would be the lower receiver).
Is it safe to spot nato 7x62 Millayo in this 308 win barrel ?
Carl B on Apr 19, 2018
BEST ANSWER: I have a 308 barrel AR10 and use 7.62 ammo all the time when shooting for fun. When I need accuracy I use 168 gr 308 HPBT

Rifle kit 503654
Most of the parts fit together like they should. However, three small parts of the lower build kit didn't fit the lower I purchased from another vendor. 1. this kit came with a roll pin to attach the bolt latch and the lower uses a bolt latch screw. 2 and 3. both takedown pins were to short for the lower. For this reason, I give it 4 out of 5 stars.

Great kit at any price!
AR-10 rifles are notoriously high-priced, but this kit offers the buyer a chance to get into the market reasonably. The fit and finish of the parts is good. The kit is complete and well-packaged. Don't bother with this if you can't put things together or have access to someone who knows what they are doing, but if you have the ability, then this is a great way to get into a rifle.

Great rifle kit and fantastic service
I ordered 2 of these kits one fits and fires flawlessly. The other fits well but had a problem with a tight chamber where only about 1/3 of factory rounds would chamber completely. I sent the upper back and in record time received a replacement along with a nice letter of how yes it was a tight chamber and the new upper was tested extensively to make sure there were no problems. Awesome rifles awesome company

had problems
I bought this kit and had read the disclaimer in red on the page that this kit might not play nice with other non-psa components. My DPMS compatible lower did not play nice with this kit but I knew that might be a possibility so that's no fault of PSA. The PSA barrel & upper centerline is lower than the DPMS one meaning the bolt will hit the lower on the lower portion of the buffer tube ring on the lower. Even though these were created problems in my setup the PSA kit had it's own problems too.

The bolt didn't want to close well which gave me a few rounds that didn't lock up. I had to use the FA to close the bolt. I had a few failures to feed. All my cases had scratches on them from the chamber which makes me think there are burrs in there and/or it's too tight. The extractor didn't want to pull out unfired cases. The extractor also marred up the rim of cases. Lastly the gas block leaked out onto the barrel.

PSA sent me an RMA so we'll see how it comes back.

One the plus side the trigger in the LPK is the best trigger I have ever owned. All my PSA LPK triggers have varied in feel. Some I've polished so they work decently well. This one right out of the bag is fantastic. It has a heavy enough pull but it doesn't creep nor grind. It just snaps after a very short pull and is really fantastic. I'm thinking it might be luck of the draw but it is very nice.

No Complaints here. Good rifle.
Shipping on this rifle was a little quicker then expected. As always when receiving a rifle kit it gets a complete tear down and cleaning. All parts fit tightly and lubed up nicely. Took it to the local outdoor range and sighted it in on a red dot scope. I loaded with PMC 149 gr. FMJBT and could hold a 1 inch group with not much effort. Like my other .308's it changes a little with the verity of ammo. Figure out what you want to run through the rifle and stick with it. Thanks to PSA and crew for another fine product for my collection.
