7.5 SBR build

[pwillis123]

I looking for your opinions for my 7.5 inch SBR build. It is going to be set up to run a suppressor. I will list what I need and have below.

Upper:
Adams Arms 7.5 Evo upper
Magpul Pro sights (on order)
AAC muzzle brake (on order)
Magpul forward grip

Lower
Aero Precision stripped lower (with stamp)
Magpul SL-K buttstock (on order)
Magpul grip

I'm mainly interested in hearing about what buffer tube and spring you would use and what your favorite lower parts are (kits or individual parts).

Thanks in advance guys!

Adams Arms 7.5 Evo is a nice upper I hear! I've actually been thinking of buying one for my 7.5". I run a standard buffer with no problems, although I've never ran it suprressed....yet! You're upper is piston if I'm not mistaken, so you shouldn't have too many problems.

LPK....I'd say CMMG, Bravo Company, or Daniel Defense....LMT and Spikes sell higher end kits that are really nice. I have the spikes enhanced trigger kit and all the pieces were really nice, but it was on the higher end.....Problem now is these kits are out of stock a lot of places. Thanks a lot Obama!

My 7.5 DI has standard spring and h1 buffer works fine never had an issue. Not one. Ran it for about 500 rounds with standard spring and buffer and also had no issues but wanted to see if using an H1 would make any difference in felt or perceived recoil. Honestly didn't notice a huge difference, so left H1 in there and put my other in a different build. I always wanted the piston 7.5 too. I've got a Surefire warden on mine and it's been wrecking the blast can pretty good, a lot of corrosion like you would see on a suppressor on a 7.5 DI. You're gonna be better off all around running a piston.

That's the same upper I'm wanting to go with as well. Haven't heard any complaints. Only thing that bugs me is that it'll eat up a suppressor pretty quick.

How so?

Powder and blasting. I think there are a couple of cans rated for it, but I don't have one of them. My 30 cal can might?

This ^.

I don't know what can you are planning on running but I don't know many, if any, 5.56 cans that are rated down to 7.5"

I'm planning on running my 30 cal AAC can on it. I was told that would work best for it.

My thoughts as well. Better check the minimum barrel lengths for the can your planning to run...

A .30 caliber can on 7,5" barrel...Make sure you wear earpro.

Also, I'd verify with AAC before running it so as not to void any warranty.
