POTD: Basic Dynamics RM277 – Subsequent Generation Squad Weapon -The Firearm Weblog


TFB’s Matthew Moss did an superb report about the RM277 – Basic Dynamics’ Subsequent Generation Squad Weapon and in today’s Photo Of The Day we will stick to up with some much more speculations.

And the photo above of course, which is the most important attraction!

Now we are searching at the RM277, Basic Dynamics’ rifle/carbine entrant into the US Army’s Subsequent Generation Squad Weapon (NGSW) system.

The RM277 is a bullpup carbine chambering what is referred to as .277 TVCM, a Accurate Velocity-created six.8mm cartridge with a polymer case for weight savings.

Particulars are scant on how the gun performs appropriate now, but they have mentioned it is gas/recoil operated. We assume that implies gas-assisted quick recoil (the barrel moves slightly although shooting) but this is not official but.

We estimate the RM277 to be about 770mm (30.3″) extended with the suppressor affixed. This is not an official figure. We estimate this going off of the M-LOK holes.

Their Flow-By means of Suppressor was heavily featured in its debut video to preserve it under US Army sound needs for the system. It makes use of M-LOK attachment points and a picatinny rail up to.

The ELCAN SpectreDR 1-4x is featured on this graphic as it was 1 of the optics featured in its debut video, but there had been various optics featured.

It has ambidextrous fire controls, side switchable charging manage, and presumably the capability to switch the side of ejection for lefties. There is an ejection port sized hole with a covering on the other side, so this is a secure bet. The magazine catch seems to be in front of the magazine on the mag nicely.

Searching at it, I like it. But I assume it would advantage from a steeper pistol grip like the Magpul K2+.

What do you assume? How would you configure the RM277 if you had been offered absolutely free hands? Which optic, mount and furnishings would you chose?
