faster than expected shipping and bolt installed and functioned perfectly. Easy to clean also.
Beautiful machine work
Only four...not completely nickel boron -LOL. Solid BCG for the money!
A true DROP-IN upgrade. Nickle Boron where it needs to be
The bolt has Nickel Boron on the main wear surfaces where you need it.
This is an awesome BCG! Very slick and well made. Have fired hundreds of rounds through it with no issues. Capable of functioning under full auto as well
Works well, happy
WHEN OPEN THE BOX -WOW-LOOKED OVER CLEAN STAKED-BEAUTIFUL NICKLE BORON FINISH-FAR EXCEEDED EX/PREFORMS SMOOTH-GREAT PRICE
This BCG is perfection, installed with very light Otis Lube and it functioned perfect with zero hiccups. I’m actually going to order another one for future Build while I can. It’s function is so much smoother than a standard.
