As part of my recent post about building a patrol rifle, I wanted to expand on that build for the viewers who may be looking to do a similar build. I used a wide variety of parts, and I simply wanted to put together a master list to give my readers and idea of what I did and why.
The primary parts of a rifle are simple, barrel, bolt carrier group, sights and handguard. So, for most of the rifle I did not skimp on the parts. To get some stuff out of the way, I choose certain parts for all rifle builds, this may be boring to some, but keeping mechanics the same between rifles is important to me.
For the barrel, I chose a Green Mountain barrel, 14.5 inch with mid length gas system and a 1:7 twist rate. This barrel was provided for testing purposes, so that is why I chose that barrel. I used a regular run of the mill low profile gas block, standard gas tube, a Precision Armament AFAB muzzle break (provided for testing) that was pinned and welded to the barrel, a Colt flat top receiver, and a BCM MCMR 13 inch rail. I added a BCM forward grip, Daniel Defense fixed irons sights, Geissele Airborne charging handle, and a white label armory M16 bolt carrier group.
Now, no patrol rifle is complete without a light, and for that I chose the Streamlight Protac Rail mount 2. Why Streamlight? Well I am not spending $300 on a light, and I have used Streamlight for over 15 years. To install the light on the rail, I chose an Arisaka Defense offset scout mount with MLOK option. I am currently running a simple red dot from Pinty optics on the rifle for testing but will more than likely not run an optic full time on the rifle, thanks to a weird astigmatism.
Now, onto the lower receiver build, and this one is just as Frankenstein as the upper, but I do not give a shit if your CDO (like OCD but the letters are in the right order), is kicking and causing you to have a Forest Whitaker eye.
For the actual receiver, I went with a Palmetto State Armory lower receiver, simply because I had it laying around. I used a Geissele lower parts kit, a BCM stock, pistol grip, and trigger guard. I chose to go with BCM items because of quality control, and well, during the recent surge of buying, they were found locally, and the grip is amazing when you have a wrist injury. Lastly, I went with the PWS enhanced buffer tube with ratcheting endplate and castle nut, and the Geissele braided buffer spring and enhanced buffer. That is the same set up I chose on a recent MK12 build, and the reasons to go with them far outweighs the reasons to go with a milspec system. I also chose the V7 ambi safety, and Geissele Tricon trigger in this build as well.
