Great Lower Parts Kit included the threaded roll pin

by -

I bought this because i have an Aero Precision upper and lower, which i bought from PA as well. Everything is perfect. I will add that this lower parts kit came with the threaded roll pin for the bolt catch and it cam with a standard roll pin. It does not show it int he picture, but it did come with mine. It was a big deal, because aero precision lowers and uppers have threaded roll pins in the forward assist and bolt catch that are included when you buy them. My lower did not have the pin for the bolt catch installed but it did have the one for the forward assist. Great product, the trigger is nice ( better than standard)

There may be better options for G.I. LPK

Had good experience with aero up until this point but I didn't even get to fire a round before I had issues. The buffer retainer nipple sheered off when I opened the rifle up to install a new charging handle. Also the magazine catch does not appear to be long enough to thread flush with the magazine release button on aero's own M5 lower. On a good note the trigger supplied seems to be very nice for "standard" all the necessary surfaces are polished to a mirror finish and has a smooth pull.

Great kit to finish your lower build.


Great kit. Great value, even when not on sale. Everything fits and the finish is fine on all the parts.
