Absolute perfection. This is an extremely well made BCG, one of the higher end BCG you can get, but it’s completely worth every dollar. Not to mention, (not that you would even need to use it) SOLGW has one of the best warranty polices in the firearms world. Don't cheap out on the heart of your build, get quality, get a SOLGW BCG

The bolt carrier group by Sons of Liberty Gun Works is the heart of the rifle. Each one is tested for function in a firearm during inspection for awesome quality control. I can't recommend it enough.

I purchased this bolt during a sale which made this an absolute no brainer. When it comes to quality Sons of Liberty is top notch. The bolt movement is smoothe the lockup is snug as long as your other parts are milspec. The staking is excellent and uniform. Some will tell you that you can get a quality bcg for way less and they have had no issues, but the difference is the quality control. They might have no issues with that specific bcg, but the next one or the one you get my have issues. SOLGW has excellent quality control they back it with a lifetime warranty. Overall you can't go wrong with this bcg especially during a sale, stock up and get a few.
Reliable & High Quality

I’ve ran over 1k rounds with zero issues the last 6 months. Ran over 300 rounds at a Tactical Games without lubricant. It has aggressive steaking on the gas key. It’s dependable and I trust my life to it.
