Need 7.5" Rail Suggestions for a 300BLK Build

[schambers]

Still waiting on the RISTA to come out of NFA jail so I haven't tried it suppressed yet.

Over than that the setup seems to be working out well enough. The griffin charging handle and Lantac big make gas a non-issue and the silent capture spring works as advertised. I've only put about 200 rounds through it though, so not a whole bunch of data yet.

The only problem I have is that there is that slight tuning fork sound coming from the flash hider. I'm curious to know how it will sound when it's inside of the suppressor.

I can live with it now but it may be irritating to me after and while and force me to switch to a muzzle brake

Nice find on the sights!

I've had these for a few years (found the front in the bargain bin at Rainier Arms) ... I'd actually prefer the actual HK height ones (a little lower)

Necropost... but I'm in the same boat and figured I'd just come back here instead of making a new thread.

I'm using the exact same barrel. BA 8.3" Hanson .300

My catch is I'm looking for something with 3 full usable M-lok slots at the 3/6/9 positions, which seems to put me with the Mega Wedge Lock, an 8" SLR, or the 2A rails. I'm kinda leaning towards the 2A because it's the lightest and least expensive, but I'm not so sure after watching the install video and seeing that the rail is secured to the nut with 4 finger tight set screws that don't even thread into the barrel nut. Anyone have any experience with this? Also leaning away from the 8" SLR because that would overhang the muzzle device, and I'd prefer to have that area free in case HPA passes.

SLR has 7.5" rails with that configuration. Their ION version adds even more.

The 2a attachments aren't "finger tight." They tighten with hex key. I was skeptical of it at first too but after installing three of them, I've not had a single issue of movement or rotation. Just take your time securing them so that the rail is centered. They bite into the barrel nut grooves, pushing the rail into the receiver.

Ah good to know. The install video showed him putting almost no pressure on the hex key during install. Since you've had good luck with them, I'll probably go that way.

Turn the shoulder down to 8", rethread and get an SMR Mk 4. Problem solved!
