Strike industries enhanced lower parts kit - Strike Industries Enhanced AR-15 Lower Parts Kit

Overall I like the product. It seems to be well made and I appreciate the over sized bolt and mag release. I really like that the detent pins have a guild pin built in. The kit worked well but it was not without issues. Two of the springs were oversized in diameter at the end and had to be cut off. I would have appreciated the ambi. safety being uneven is size, as the full sized off-hand selector rides in your grip. I had to switch it out for the flat plate. Time will tell on the longevity.
