Bottom line, lightweight BCGs are hard to find. Buying one on a whim is even more risky. I rolled the dice on this and I believe it's going to be a perfect fit for my build. Well made, and solidly constructed.

Without overthinking it, it is a lighter bcg and it cycles flawlessly. Granted I’ve only had about 300rds through it on a 16” 223 with a mid length gas tube and a h2 buffer system, I haven’t had anything to complain about.

this is an awesome and extremely well made lightweight bcg! the finish is flawless and it functions perfectly with not one glitch or problem that you might expect on a lightweight AR build….I highly recommend this one and will likely be purchasing another one soon.

This is an excellent low mass BCG. Has run flawlessly for me in an 18" 223 Wylde built for 3-Gun which has a total weight of less than 6 pounds. I like my builds with an upper that retains the forward assist, which makes this BCG ideal for my preferences. Many low mass BCG's are constructed without the grooves for the forward assist in order to minimize weight, but if you like a forward assist on your AR builds, this is a great BCG to consider.

weighed in almost exactly 8.6oz, finish is very nice, works perfectly with a lightweight buffer and an adjustable gas block. i would defiantly recommend to anyone looking for a low mass bolt carrier group

Was looking the save a little weight and add more functionality, it did that, the finish is shinier than pictured. Added the bcg and an adjustable gas block, (definitely needed with a lightweight bcg) and she’s been purring ever since
