I have had a CMMG 16" dedicated 22lr upper for quite some time and after some slight tweaking it has been very reliable and accurate. It goes to the range with me almost every trip and has thousands of rounds through it. Based on that experience I have been wanting to build a braced pistol version for a couple of years. I finally bit the bullet and ordered up some parts. I started with a NBS billet 9mm/45 slick sided upper on sale for $46. This is my first experience with this brand but I can tell you they are fantastic. The finish is great and the machine work is spot on. I also like the lines and how it matched up to a poverty pony lower I will use with it. I also ordered a MAS defense Nero 5.5" free float handguard for $55. I also have never had any experience with MAS but for a budget build it seems solid. It matches the lines of the upper well and was easy to torque down to 38 foot pounds and time to the upper. The rest of the parts are known quantities. I used a CMMG 4.5" barrel and charging handle made for a dedicated 22lr build. I stole the CMMG 22lr bolt assembly out of my other upper for now. I finished off the barrel with a kak flashcan to clear the rail and put a magpul bu rear sight and a utg flip up front sight I already had to allow me to shoot it. It will probably get a red dot in the future.
Here are all the parts before assembly.
I can tell by how hard it is to lap the front of the receiver square that the finish on the NBS upper is durable
I briefly thought about leaving the handguard off for a real minimalist build but need the rail for the front sight for now. It does look pretty good without it though.
And the final product weighs 5# 2oz with an empty 27rd black dog mag.
Here are a couple more pics, one with suppressor instead of flash can.
I ran a mag of cci standard velocity through it with suppressor to check function and it did not hiccup. I will try and get some range time soon to see how accurate it is but I am happy how it turned out and encouraged by the initial function test. Will report back after some range time.
