Good to go
Fit and finish we are great. Functions as it should. Luth-AR is basically DPMS reincarnated so I'd expect it to be good quality. Without destruction testing I wouldn't be able to confirm toughness and longevity.
Ar15 bolt catch
It broke into two pieces after 20 rounds in my new Epc9 built. Bad quality.
Really unhappy
Part didn't fit. After closer inspection it had a slight bow to it that made it too tight in the milled slot. I couldn't be more disappointed in this part.
Broke after 1 use.
bought several to finish out some parts kits. 3 total. 2 shattered after 5rounds on two different 9mm AR lowers. trying to find where i placed number 3 so i can chuck it in the garbage. switched out to battlearms development and strike Industries on the 9mm Lowers. zero issues after several hundred rounds so far. its a shame as i have had good luck with LuthAR parts in the past. maybe they were over hardened and brittle. will add pictures later.
