“These BCGs are hard to beat, both in functionality and, especially, value. The QPQ treated surface is very eye-catching, and the tough, nearly corrosion-proof nature of nitride makes it a no-brainer for nearly any steel firearm part. The bolt rides/rotates very smoothly in the carrier, even without oil. While these BCGs don't boast some the 'fancy' (imho un-needed) features as some others out there, these are everything one could ask for in a solid BCG that will give reliable, hard-wearing service for a VERY long time. The price is the biggest selling point for me, and these are my go-to from here on. I plan to use one in every AR-15 variant I build... -AD”
“Toolcraft bolt carrier groups are the only bcg's I'll buy. I've used several of them in my AR pistol builds, and have NEVER had an issue. I can always rely on them to work and perform. And they are a steal in my opinion price-wise, considering the level of quality. I've purchased other more expensive bcg's that were completely lacking in quality when compared to Toolcraft. This is my go-to bolt carrier group, hands down. Don't hesitate to buy one of these amazing bolt carrier groups. I have tens of thousands of rounds through my AR builds, using these bcg's with zero issues.”
