Works great
Changing out a barrel on a milspec AR and while they are usually 'plug and play' it is best not to leave it to chance. These worked great.

Go/ No Go gauges
I've been wanting a good set of headspace gauges for 5.56. When this set FINALLY came back in stock, I thought I'd better get them. I also purchased a 5.56 field gauge.......different brand, just to have all three. I also caught these on a free shipping promo....NICE! I watch, learn and enjoy the videos of Steve and Caleb that Brownells produces and distributes FOR FREE (thank you, Brownells, steve and Caleb), so when I can i like to make my purchases from Brownells to support tose efforts.

Must have
Overall, something that is important to have if you’re building A.R. 15 or buying a used one. Technically you do not have to take out the extractor or the ejection spring, but do not slam it into the bolt or barrel.

Works
Come in a good sturdy case to protect them. Came in one case with a rubber ball between them, wish they had come in separate cases. But good products.
