Yeah, just a good old fashioned, no frills, solid BCG for the 6.5 Grendel. Nitride is nice and slick, it lubes nicely, and it overall gets the job done. This is what I have entrusted to cycle the action on my very favorite gun, so it's pretty great.

Put this in the new 6.5 Grendel build. No complaints from me. Works great, looks good, if it holds up like other aero products then I'm not going to shoot my gun enough before it wears out. I suppose if you're someone that shoots the absolute heck out of your guns you're better off going Lantac or something much more expensive but for most people aero BCG does the trick just fine.

Nice clean finish, functions well. I have used cheaper bolts and was not impressed. This is an AR part you do not want to skimp on. Aero Percision is solid, reliable and will not disappoint. Received pretty fast after order as well.

Great bcg, fit my upper perfect and runs smooth. cant ask for a better bcg for the money, i will be switching my other rifle soon. hard coat and type 2 face is a necessity anymorehighly recommend instead of a budget bcg, always spend the few extra $$

This bolt carrier group works with 6.5 grendel type 2 chamber. It has a black nitride finish which was very well done. It is easy to clean and the nitride finish is tough and requires very little lubrication. Price is really good for the quality of this bolt carrier group.

Beautiful looking bolt carrier. Super smooth nitride finish with Aero logo. This thing is a work of art. I bought these just for the carrier assembly, as the Optics Planet price was so good. I got 10% off plus optics planet bucks back. I plan on using this carrier with my 5.56 Colt bolt. I have been very happy with Optics Planet. Prompt shipping, good prices, professional transactions so far.
