The Gen3 PA10 upper receivers are functionally and aesthetically compatible with Gen2 and Gen3 PA-10 Lower receivers. However, there are external cosmetic differences when mixing Gen1 with Gen2 and Gen3 upper and lower receivers that some may not find appealing.
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.
