Not long ago, I mentioned having the urge to start a new project. My observation back in June was that my main rifle, which began life as a KISS iron sight rifle, had grown in weight and capability to become my go-to for most things. Despite that, I still really enjoyed the basic configuration. I started sketching out a new lightweight minimalist project, which I’m designating my “field rifle,” or “walking around rifle.”
This is the original mockup I did on Gunstruction.
At this point, I have the lower assembly completed.
- Rainier Arms lower receiver
- Sionics lower parts kit
- Magpul MOE Rifle Stock
- Hogue overmold pistol grip without finger grooves
- ALG ACT trigger
- Magpul MOE trigger guard
I’ve been playing with this assembled lower on my 20″ upper to see how I like it. So far, so good. The Rainier lower, which I presume is made by Mega Machine based on some of the features, is very nice. The roll pin holes were tight, which is not a bad thing, and took some finesse on my part. I’m not one to mind my lowers looking a little “used,” but I can see some people being concerned about the effort required to drive in certain pins (particularly the trigger guard).
The Hogue pistol grip is quite nice, it has the nice rubberized texture Hogue is famous for, a subtle palm swell, and is shaped more or less like an A1 grip. The Hogue grips have a little lip protrusion that is intended to fill the gap created by the standard AR trigger guard. However, since I’m using a Magpul MOE trigger guard, which is designed to fill the gap itself, I had to cut the “lip” off the top of the grip. No big deal, less than a minute with my Leatherman.
The MOE Rifle stock is awesome. I installed one on an unfinished 308 lower years ago, and have shot them on rifles I’ve built for friends, but never put one on one of my own ARs. It offers a very nice cheek weld and fits my length of pull perfectly.
The ACT trigger has been in my stable for years as a backup to my Geissele triggers. It will be front-and-center now, though. It’s just a good all-round mil spec style trigger. The single stage has a very minor amount of creep, but I don’t really care given the style of shooting this project is intended for.
Going forward, I plan on using a Faxon 18″ Gunner barrel (with a Criterion Ultralight 18″ in close second). Following that, I’ll be finishing the project with a Rainier Arms forged upper receiver (without forward assist), Rainier bolt carrier group, and Magpul MOE rifle handguards mounted behind a standard F-Marked front sight tower. For a rear sight, I will likely use the BCM carry handle I already have on hand, but may go with either an LMT sight or Larue A1 style sight in the long run. I plan completing this project before pre-election panic buying gets into full swing, which will make parts dry up pretty quickly. That is, of course, assuming the parts I want are available in my desired timeframe.
