Am looking to pick up one of these two rails for my SBR build. I am planning on going with a 10"-11.5" barrel. I’ve done a bit of research on the two and both rail systems are getting positive feedback.
I’ve also been considering the new BCM keymod rail but cannot figure out when it’s supposed to be released.
I have the Rainier version of the evolution and it’s been great, very solid lockup to barrel nut/bushing deal they got going on there and comfortable but does get warm after extended range sessions. I like them.
I like the VRS-T, but did find it heavy. Also, depending on what length they say it is, add about 2" and that’s the real length. For that, Diamondhead -1.
On the plus side–it’s compatible with Magpul rail pieces, except instead of standard Magpul 10/24 screws, you need 10/32 screws. For that, Diamondhead +1.
As for Samson’s Evolutions, I find it good, easy to configure, lots of options. It’s slightly thicker than a Troy Alpha, but not as thick as some other round tubes. Both are good options, preference really.
It also feature GPS and facial recognition with pre loaded profiles of the top ten terrorists. There is an optional satelite comm module for the spec op community
