Odin works pistol buffer tube vs BCM pistol buffer tube.

The Shockwave has a thin fin to put against your shoulder. It's going to get uncomfortable quick.

No it doesn't & no it doesn't

The Shockwave is thin and hard. Yes, it's going to get uncomfortable quick. Been There. Done That.

I've got the Vltor kit on its way from Dvor (OpticsPlanet subsidiary; 20% off FTW!) for my own pistolized-Mk 18 build, though mine's being set up with its Blade ratcheted as far forward as possible. (It's on there not so much as a forearm brace, since I have an AFG/thumbrest combo set up that lock really tightly with the support hand, as to break up the "gun" outline if the thing prints in my laptop case. Yes, I carry a BIG laptop... weighs more than a complete mil-spec M4 and all its accessories in the factory shipping box too.) I may even end up installing the Blade backward, depending how the lines go... or removing it entirely since I'm a southpaw and the tube needs to clear my forearm in the drawstroke.

Corycop25 and I were comparing notes about running shorty ARs with A5 REs and the Sprinco green spring. Get the VLTOR A5 pistol RE, 5 oz A5 buffer and green spring.

This is the setup I am using on my Kino "pistol" along with a LAW folder and Tail Hook stabilizer.

How is it working for you? Cory says his has virtually no recoil

Hopefully, I'll save you some time and tell you to just get the A5 system. Hands down, some of the best money spent IMO.

Thank you for the recommendation. I think I will go with the BCM tube kit for now. I read that DD sells their mk18 sbrs with an H buffer, so I figured the H2 should be fine. I’ll test it and see how it feels if things doesn’t go well, I will definitely go the vltor a5 route. I think for pistol brace the KAK shockwave blade pistol brace seems like a good choice. It has a screw on the bottom to tighten the bolt, so that the brace doesn’t move around due to recoil. The ATF recently clarified shouldering a pistol brace isn’t a crime anymore, so that’s a relief lol.

[CoryCop25]

Would the BCM pistol buffer tube kit with H2 buffer weight work well for the mk18, if I go that route instead?

The H2 will be too light with a can. Go H3 or as most have stated, the A5 is the best route.

I agree, very mild recoil with the A5H2/Sprinco Green, which is my typical setup, but I pick up an A5H3 for shits and giggles to run through my various A5's to check it out but have made it out to the range yet.

[Shiz]

I have wondered for a while, is it better to use an a5 buffer system, h3 buffer for running suppressed or do an adj. gas block? What about both? I have a5 on a couple of my rifles, but would never put it on my pistol upper as it is against the law. I seem to remember something a long time ago from C4grant that he ran a LMT advanced carrier, adj, gas block and a5 RE on his silenced SBR. I just don't know what the benefit would be, one over the other. (a5 vs adj. gas block)

[tehpwnag3]

Shiz -- If set properly, the AGB with a lighter/lightest buffer would be ideal. Less reciprocating mass equals very fast follow up shots (this is the 3 gunners "secret"). If ultimate reliability is the goal, I would be inclined not to do this, but that doesn't mean it couldn't be tuned perfectly reliable for certain ammo.
