Its ok, but have yet to try it /: detent pin wont fit standard milport lower its belled - Strike Industries Enhanced AR-15 Complete Lower Parts Kit

you figure that it would come with properly sized parts... the buffer tube detent pin was definitely belled and wouldnt fit the channel on my stripped MilSport multi cal lower....the spring was a tight fit into the channel but the detent spring most definitely doesnt fit in the designated channel for my lower (pretty basic lower), and also as mentioned by someone before, the trigger parts came with aluminum shavings in the bad >_> just uh a tad lax on quality control but the detent pin not fitting kinda is upsetting /: hopefully they send me one that isnt belled. ill update as it goes after i take it to the range
