To ensure compatibility and reliability, these uppers are test fired with 7.62x51 NATO ammunition during the manufacturing process.
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.
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.
