Could anyone give me advice on building an AR-10? I know parts wise they arent as compatible compared to AR-15s. I was looking at just grabbing a PSA AR-10 lower but their description says they only recommend to use PSA uppers. Has anyone built an AR-10 using a PSA lower and a non PSA upper?
To be clear I’m new to the whole form 1 thing. I know nobody knows if the ATF will still approve form 1s after July 1. However, say that they accept form 1s after July 1 and you take a stripped lower to get engraved. Would the person who’s engraving the stripped Lower want to even engrave it since it’s not a complete firearm? And with the new ban, technically anything assembled after July 1 is breaking the law. Would the engraver even want to do it because of liability or something?
