PSA AR-15 Complete Lower Magpul ACS-L EPT Edition - Black, No Magazine


PSA AR15/PA10 Enhanced Polished Trigger (EPT)

We start with our standard single-stage government-style fire control group, finely polish the contact surfaces and then coat the hammer and trigger in a super slick nickel finish. The result is a trigger that is substantially smoother than mil-spec. A great economical upgrade.

I don't fully understand why I have to be 21 to buy this. I am 18 year old that lives in VA, and I am a legal gun owner. Can someone please explain?
Andrew E on Feb 16, 2019
BEST ANSWER: A few possible reasons, one being that the lower is marked "Cal Multi"which insinuates it could be turned into a pistol, the other being it may be a policy by PSA that lowers can only ship to persons over 21. The second reason is more likely.
