What is the WMD GUNS - M16 5.56 NICKEL BORON BOLT CARRIER GROUPS?

Each WMD bolt-and-carrier set is precisely machined from high-grade steel alloy to government M16 specs, then given WMD's proprietary NiB-X® nickel boron coating that results in a super-smooth, harder-than-chrome surface. NiB-X® reduces friction to the bare minimum and is impervious to corrosion and abrasion. The slick finish also keeps carbon from adhering, so clean up is much faster and easier than with standard parts. Ideal choice for 3-gun competitor sand other high-volume shooters. Available with a matching NiB-X® coated hammer for the smoothest cycling. Also available as an M16 Bolt Carrier Group.

SPECS: Carrier – 8620 carbon steel. Bolt – Carpenter 158 steel alloy. Both have Nickel boron finish, silver. Extractor includes black buffer, black O-ring, and spring. Fits mil-spec AR-15/M16 upper receiver. M16 carrier available.

Looks great

This BCG looks awesome, and feels very slick right out of the package. Mine did come with the WMD logo engraved on the bolt also.

Excellect BCG

Built like a tank, pleasing to the eye, and easy to keep clean. The NiB coating not on,y looks good, it greatly adds to the inherent lubricity of the BCG. I will be buying another one soon. Highly recommended

Beautiful BCG

I've not put this BCG into service yet but out-of-the-box I am impressed with the beauty of the finish, the heft of the overall BCG, the attention to detail. My initial impression...I wish I had purchased the M16 NiB-X~ Bolt Carrier Group for my previous builds as well. Time will tell but I'm very appreciative of Brownells lifetime guarantee and their excellent Website making these purchases secure, convenient, worry free. I've done the searches and Brownells.com is a winner for selection, price, quality, shipping, customer service; they're worthy of our support!

good but could do better

This is really good quality, and looks very sharp. Went shooting and after, gave it a bath in some heavy duty cleaner. Got busy with other things and didn't get back to it for about a week. When I took it out, the coating was off giving the bolt carrier and firing pin a pitted appearance. I should've known better and considered the possibility it might happen, but didn't believe it would. Anyway, I upgraded cheaper with Brownell's version of a nickle boron coated bcg, and am happy with it. Can't speak for the durability of the Brownell's bcg but it works and it's cheaper. The trigger assembly that came with this wmd set felt gritty on the pull, so i upgraded with a trigger assembly from aero precision. This is a good product, but it just wasn't meant for me.

Survived Rifle School

Just put this to the test with a week long rifle school. First two days the bolt cleaned up and still looked almost new. By the end of day 5 the bolt (not carrier) had some darkening and was discolored. Despite the discoloration the Nibx is still on the bolt and it cleaned easily. Function is more important than looks and this BCG performed 100%. Would definitely purchase again. Probably close to 2k rounds in 5 days.
