Great way to get a bunch of spares!
Purchased these for spares, excellent price and fast shipping
Bought as back ups.. cant have brought backups
It was a quick delivery & a great quality product! They made a noticeable difference on my rifle!
Good product at low price. But GREAT customer service and very FAST shipping!!!!
got my rifle back into proper working order. these are a must have item. buy at least 2 more sets than you think you need so you have them for the next time this consumable item needs replacing!!
Purchased these at the same time as the BCM Gunfighter Vertical Grip. As I have put over a thousand, borderline gentle, 55g 5.56 x 45 rounds through my S&W M&P15 I noticed upon cleaning that my baby had an ouchie. So as any good father would do I remedied that situation and purchased these. Shipping was quick, and upon install I noticed a major difference in the amount of friction the bolt carrier now had which I could only assume was a highly efficient gas system for my pew pew. Super happy with the results and BCM did not disappoint. ‘Murica!! Oohrah!!
Just another great product BCM keeps in stock that is awesome and important to have spares of. I love BCM!
