5 of 5 7-inch C4 Rail System October 27, 2017
Reviewer: Grant Rasmussen from Charlotte , NC United States  
This was my first time buying from BCM and it won't be my last. This rail system fits a traditional M4 with a fixed front sight and was easy to install. It arrived before it was suppose to and came with some cool BCM stickers. This rail system is light-weight and has been a dream to shoot. Would recommend anyone to purchase this if you got the dough.

5 of 5 Very Good! November 11, 2015
Reviewer: Matthew Drinkwalter from Billings, MT United States  
Very good rail system and easy to install. If you know your way around AR's in terms of take down internally and externally than you will have this installed quick and be very satisfied. A lot of rails on the market but I believe centurion along with Daniel defense are among the top two companies when it comes to rails. I popped my gas block off than pulled my gas tube. I than took a drummel to my delta ring. I than snipped the front clamp off. Once that is done I installed a new gas block, which I recommend because their inexpensive. I also put a new gas tube in. I than installed my rail, leaving the factory barrel nut I than installed the rail. Impressed to say the least. Very light but strong and fits snug against your upper receiver. A hell of a product and centurion did well by having it clamp to barrel nut.
