Blackpaw Survival Aeroshell 33 MS Grease

Comes in a small jar similar size to the "Carmex" lip balm. Provides more than enough grease for a build. Will probably be enough for 5 builds. The brush that comes with it is garbage. Bristles fall out and stick to the grease on your rifle. My advice is to discard the brush and use something else. Knocked 1 star for that reason. The grease, itself, is perfect.

Best gun products seller on Amazon - I received a very nice, hand written sincere note thanking me for my purchase, what's better than that? Super fast shipping, ultra high quality product. This is the best assembly grease around at a great price. I've already used the little jar for two rifle assemblies and there is still enough for 3-4 more. Highly recommend, thanks!

While I haven't as of yet had to change any barrels I've used this on I feel confident it's the real deal and will perform as advertised and I wanted to go ahead and and suggest dealing with Blackpaw Survival. Had a nice personal thank you on the receipt and that earns the final star for me. Great job to those involved in this operation, you've got the right idea.

Exactly what I was looking for when I needed to do a barrel swap on my new AR. I'm a perfectionist when it comes to doing things and when I started researching on how to do a barrel swap on an AR, everything I read said to use Aeroshell 33 MS Mil-Spec grease. This is the recommended grease by the people who wrote the AR 15 armorer’s manual. In forums people say to just use motor oil or auto grease. If you truly care about your rifle then do it right people and spend a couple bucks for this stuff. Fast shipping, grease came with gloves and a brush and a nice little personal note. Thanks Gary.

Just the right quantity. Used it on 2 builds already, for the barrel and muzzle brake. I really like that it got here quickly and included a little brush. I tossed it into my toolbox to await the next build

This stuff is great! It was the last thing I needed to add to my tactical .223, in order to call it complete. I still have plenty to finish my 300 Blackout, once I get the head-space checked. Good luck on your Blackout build, Gary, and thanks a bunch! Go Broncos!

Great price and perfect size for my Gun smith tool box. This should last for multiple AR 15 builds. No need to purchase the full tube of grease. The hand written thank you note was a nice touch. Very happy with this purchase. Will buy again when I run low.

A little goes a long way. This is a great product for AR barrel installs. So far I have used this to install 3 barrels. I think I have enough to install 3 more. Very fast shipping. Package came with rubber gloves and application brush.
