Brownells USA No Nonsense Thread Protector 15/07/2012

Needed a simple, off the shelf thread protector for the stainless barrel I put on my AR-15 varmint upper. The YHM thread protector fits like it was factory made for my barrel. Fits snug against the shoulder, perfect O.D. to match the barrel profile and flush with the muzzle. What's even better than all of that, it was very inexpensive. It's G2G!
