Made to exacting quality standards, the Walker Defense Research low-mass Bolt Carrier Group BCG is approximately 67% of the mass of a traditional steel full-auto profile Bolt Carrier Group BCG, while offering exceptional durability from the use of Grade 5 titanium coated in Ionbond DLC (Diamond Like Carbon). The bolt itself now features a nickel boron coating for heat dissipation, ease of cleaning, better lubricity, and enhanced reliability. To truly get the most out of your titanium Bolt Carrier Group BCG, we recommend using this in conjunction with an adjustable gas block. This is an excellent addition for a lightweight build or for use in competition (3 gun) shooting.

Machining is excellent. Finish quality is excellent. Functions normally in a normal gas system, but tuning your gas system and recoil springs will be necessary to get the full benefit of the lighter weight without compromising reliability. Definitely reduces felt recoil impulse in any case, but tuning will bring out the best it has to offer. I actually replaced the chrome firing pin with a WMD NiB-X pin to get full Nickel-Boron coating on the bolt group internals, but the original would have probably been fine. The bolt has radiused lugs similar to JP's enhanced bolts, but does not use the thickened area around the cam pin that the JP bolts do. However, I believe that feature is proprietary, so it may not have been an option here. The bolt also has old-style three piece gas rings rather than the more modern helical type. That's easy to fix if it bothers you, and not at all crippling to begin with. Still, it would have been nice. All in all, though, if you have to have those features, it still makes sense to buy this carrier group with the bolt and replace it with whatever bolt you prefer, because you're still getting a good quality Nickel Boron coated bolt that can be kept for a spare or used on another build for only a very small markup over buying the carrier by itself. As for me, I think I'll be upgrading a few minor components, and leaving the Nickel Boron bolt in, because its machining is very good, and it's 9310 steel. It's well beyond the level of durability and quality I need for Service Rifle competition.

Did not know too much about the company but have heard others speak highly of this particular BCG. So, I took a change and purchased one from OP. I have purchased and now have been made part of my builds, V Seven, RCA, 2A Armament, Lantac, and BCM. This bolt carrier group outperforms all others with the exception of BCM. I wish I had purchased more Walker Defense BCGs in place of all others.

This is an excellent and very light weight BCG. You will need to either use a heavier buffer to slow down the cycling and/or use an adjustable gas block to turn down the gas. This is a top notch, superb quality BCG. It's light weight and can be used to reduce overall weight AND reduce recoil by having less reciprocating mass, BUT if you can't turn down the gas, you'll very likely cycle too fast and possibly induce malfunctions. You'll love this BCG as long as you take into consideration that a BCG is one component in the whole system, and the pieces need to work together.

This BCG is light weight. If you want to take full advantage of that you need to combine it with a gas system that can reduce the amount of gas introduced into the system. Otherwise, this will cycle too fast. As long as you know what you are getting into, this is a fantastic BCG. But a BCG doesn't operate in a vacuum and has to be paired with less gas to slow the cycling.
