Ok heres my plan, I have a 20" DMR, I plan to swap out the barrel on it to 6.5, my question is, who makes a rifle action 18" barrel? I have looked at allot of different barrels but all seem to be mid action in the 18" and rifle in the 20". Adams has a nice 18" that is fluted but its a mid sytem, he does not offer that (fluting) in the 20, which imo, would help drop the weight quite a bit, as my DMR, is quite a bit less than my old Hbar.
I bought a 20" and had Adco Firearms cut it down to 18.25" and thread 5/8x24. This gives you a rifle length gas system, access to the wide world of .308 muzzle devices, threads that are guaranteed to be concentric to the bore (important if you're going to mount a suppressor), and a really nice muzzle crown. I have only fired Hornady 123gr Amax factory ammo from my rifle, but I can report that the rifle works perfectly and throws brass to my 4 o'clock about 6 ft away. One suggestion: make sure your upper receiver has extended feed ramps; this feature enhances the reliability of the bigger bore AR calibers like 6.5G and 6.8SPC.
Here is the rifle with a standard flash hider:
And here it is with a Surefire suppressor (reflex-type):
Check Black Hole Weaponry.
Also, Satern will probably make whatever you like.

Both chamber the LBC .264, although either might chamber the Grendel in the near future.Originally Posted by Drifter

Dang, that is real close to my set up, I have the M4 feed ramps on my upper, I'm running a Danial Defense 14" front rail, with a PRS stock, but from the looks of yours maybe I should do a DD 12" and swap out the PRS for my SOPMOD needing a home. What scope setup are you using? I'm setup now with a Mark 4 3.5x10 TMR reticle, with a M262 cam/turret. I used ADDCO before and their work is top notch! Looks like the way I need to go, especially since I plan on using my AAC 762SD.I bought a 20" and had Adco Firearms cut it down to 18.25" and thread 5/8x24.

I'm using a Nightforce 3.5-15x50 F1 FFP mildot/mil zero stop scope in a Nightforce 1.375" Unimount.
I've used the PRS on a couple of rifles, and don't like the weight or bulk. The LMT SOPMOD has great cheekweld, but I've settled on the Magpul ACS because it is a bit better for prone shooting (the shape is easier to grasp with my support hand).
You will LOVE shooting your Grendel suppressed...
Which suppressor is that? 7.62 or 6.8"
6.8
Surefire used to carry a 9/16 break for their cans, then dropped it for some reason.
we ofer that barrel its on my grendel just look at our site and i have plenty of pics just check my posts
