I'm trying to piece together my SHTF rifle and I know what i want, but I don't know if it's viable. I want a 6.5 grendel 10.5 in barrel with an AAC 6.8 suppressor. Does anybody have any experience with this and know if I will run into dwell time / cycling issues. If it is viable, will I be constricted to only using certain ammo loads?
10.5 barrel & suppressed?

This also is on my future project list. I would think if the gas port is sized correctly, a 10.5" carbine length gas system in 6.5 would run like a top. I have a 10.5" .223 that I had a lot of trouble with short stroking initially. It now runs fine after opening up the gas port in the barrel. One thing you would need to be careful of is not opening it too much for shooting suppressed. I have a switchable gas block with ports sized for shooting suppressed & un-suppressed.NRA life, GOA life, SAF, and TSRA

Alexander Arms markets a 10.5" upper assembly:
In your first post you said you wanted to be able to "hit out to 500 or 600 meters." I doubt anybody has tried that with a 10.5" barrel, so I can't tell you how feasible it is. In any case, from that barrel length you likely won't get bullet expansion/fragmentation much past 200 meters.

Had mine cut to 12.5-inches and run a 308 can on it. works great on full or semi-auto. i think i'm running an H2 buffer in it. Model 1 Sales barrel and havent changed a thing except wacking off several inches of barrel length. darn thing shoots great and i love the 6.5 on the AR platform. great hunting rifle as well as SHTF as far as i can tell so far sir...

nice setup Variable. i really like the short barrel in the 6.5 and i can shoot mine without hearing protection with my 308 suppressor. very quiet actually, and the downrange performance is outstanding compared to the 223 obviously. its great to have such a fine cartridge that'll work in the AR platform without the heavy weight of the AR10. that was the main selling point for me. i was on the fence for about 6 months trying to decide between the 6.8 or the 6.5, as i had read that the 6.8 was supposidly very efficient in short barrels. not sure if the same can be said for the 6.5 but i suspect it is as i dont get a flame thrower effect when shooting without suppressor attached. cant say that for the 223 as it'll cook bacon when running a shorty. i had to tinker with several different buffer weights in mine before it would run on full auto without and with the suppressor, and since figuring that out its been 100% since. i'd like to tinker with some subsonic loads if there's some data that indicates it'll cycle the action, but now that the 6.5 has been unleashed via SAMI specs and whatnot, i figure it wont be long till somebody comes up with a subsonic load that might work.

Are you seeing 2400fps out of your 12.5" barrel for the Hornady ammo? If so, that bumps up my interest in a 12.5" Grendel by a magnitude...

I get 2520fps out of my 16" middy pushing 120gr SMK's. I think there is a lot of potential for the 100gr projectiles to exhibit some impressive velocities out of the shorter barrels with faster powders. I'm thinking that we should start with X-Terminator and work from there with faster powders out of the short pipes.
We haven't really played around with the Grendel's potential in the area of SBR's enough, I believe. It's so attractive as a precision shooter, that the SBR field gets largely ignored. Probably time to change that...
