Exactly what i wanted. The colbalt looks great. Jig did its job.

Very well made device....... Not sure it eliminates all recoil like they claim. But This Muzzle Brake definitely works wonders on my 16” .308 barrel. I would recommend this brake to any one looking to minimize recoil on their rifle!

Install went smooth as can be. I used a Spikes tactical midlength gas tube. I measured set screw spacing then dimpled barrel. I little blue lock tight and she was installed. Problem was when I got to range. Gas block was installed onto a Brand New Faxon Heavy Fluted .308 — 16” barrel. Seems the system was overgassed when Aero gas block ran all the way open. So I tried to adjust properly by closing gas block all the way down, and running a single bullet in Mag. Well it turns out that my gas block ran full overgassing in all 15 adjustment clicks on this gas block. No matter what I did, I could not get gas block to close off port. I did everything the instruction sheet said and even watched a couple videos on YouTube. I have 2 other cheap ass adjustable gas blocks that work 100% and was able to tune properly on both firearms. Something is amiss on this Aero Gas block. So after 25 rounds and some cussing and multiple double checks on click adjuster I gave up and cased my new $1500 Aero Precision rifle. I set her in safe. I Plan to call or email Aero this week and going to dissasemble hanguard and gas block this weekend sometime...... I cant see what could be problem. Absolutely no noticeable difference in gas pressure on all 15 supposed restriction clicks. And no way to get gas block to close all the way short of breaking the adjustment screw by using a big ass Hammer. Kind of a disappointment so far. Maybe it is a simple fix. But fuk I spent some serious money and meticulously assembled this thing only to have to take her apart again

I am sure by now most people know that P80 makes a great product so the one thing I will add is that if this is your first 80% build I would highly recommend you check out Marinegunbuilder on YouTube before you even get started on your build. Another thing....the color of the Cobalt (which is hard to tell from in the pics) is a charcoal grey color. It looks almost black in indoor light, but outside looks charcoal.

Shipped extremely fast, packaging was done well and it came in exactly as I wanted. I will order again.

It came in quickly and I had been having issues with my Brownells barrel. I would chew up pretty much any factory ammo I ran through the rifle. I had enough, ordered this barrel and a Rubber City high pressure BCG. Shoots around MOA depending on load, brass looks clean, and runs smooth. I couldn't be any happier. Also, with the fluting the rifle got much lighter.
