Sorta harkens back to what I tink a first gen iteration of the TSC Navy ST started life as.For me the KAC RAS and Surefire Lighted Forearm were both good options, but I really disliked having to compromise between mounting surfaces or a solid light source. I’m not a huge fan of permanently affixed Pic rails with or without covers and I also disliked compromising on the suppressor installation with the SureFire forearm like you pointed out.
So in the absence of finding exactly what I wanted, I decided to make it myself. I tried to keep it as true to “old school effect” while using “new school tech” to evolve my patent-pending forearm to a new plane of existence.
- 6061-T6 Aluminum extruded by an aerospace/defense company
- M-LOK mounting surfaces at the 3, 6, and 9 o’clock positions
- Additional mounting surfaces for add-on rails of any type at the 2, 5, 7, and 11 o’clock positions
- Retention via 2 cross bolts, so a pretty nice quick-change setup
- Low profile full-length Pic rail the entire length of the firearm. I can honestly say I don't really miss the iron sights since I predominately use optics of some type
- Front end completely open for any attachment approximately 1.5 inches in diameter, since I wanted to be able to use this on a future SD build as well
Works incredibly well on everything I’ve tested it on thus far: G3K, MP5, and a 33. (The MP5 is sporting a registered sear, which helps a lot since the majority of testing has been on auto and with full mag dumps).
I love the ACR stock and have not been disappointed in it at all. The pictured stock adaptor was 3D printed but I’ve got a batch coming back from the aerospace/defense company that are aluminum and oh so pretty. The stock height for me is perfect since it gives me a solid cheek weld with almost every rot dot or scope I run.
I kinda think my forearm on a normal MP5 also gives it a bit of an SD look. And I don’t have to compromise on anything I want to attach to the barrel.
