Reviews & Ratings for Walker Defense Research Research Titanium Bolt Carrier Group (BCG) — 8 reviews — Page 1

First off, shipping was fast. Showed up perfect, intact,and this thing looks, feels, and fits great! I have not shot with it yet is why only 4 stars, but i am super excited to update after shooting with it!

Works amazing and flawless without any issues. Have it in my 7.5” 300 Blk out pistol, works suppressed or unsupressed without any hesitation. Pairs well with my superlative arms adjustable gas block.

Works flawlessly on my 7.5” 300 Blk out pistol. Works great suppressed or not suppressed without any issues. Have a titanium superlative arms adjustable gas black as well!

DD 10.3" barrel. H2 buffer, Tubbs rifle spring, carbine extension. Ejection is at 4:00 unsupressed and 2"20 suppressed with SF Mini2. Not a single malf with either config.

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.

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.

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 a...
