Suppressing a 10.5” AR pistol

[Squash_edc]

hey guys, I just finished assembling my first 10.5" 5.56 AR pistol. It is a palmetto state Armory upper and an aero precision m4e1 lower with a psa parts kit. I plan on suppressing it in the near future and want to know if there are any parts I should swap out before then. Adjustable gas block? Different buffer? The handgaurd will be replaced with a manticore arms 9" transformer rail to leave room for the suppressor. This will be my first suppressor so any advice will definitely help!

Might want to start by measuring the inner diameter of your rail and seeing if it will fit.

Good looking AR by the way.

Lol just edited the post the rail is being replaced with a 9" in the next week

Thank you man! Super happy with my first build!!

Shoot it without any changes first. If overgassed or whatnot after getting the can, then make changes.

If anything I'd at least put a proper H1 buffer in it as it likely has a traditional carbine buffer as is. 10.5" with carbine length systems is close to the MK18 the military uses and they all come equipped with H1s. Not that it is needed if your gun runs fine as is, just doesn't hurt. Slows things down a bit as is and makes it a little smoother.

Would I need to replace the buffer and spring on it or just the buffer?

Just the buffer. You could buy a kit like the Noveske one that comes with a slightly quieter spring and a H1 buffer.

I literally just built the exact same pistol. Except with with differant brace.

Then...... it's literally not the exact same pistol.

I'll be the dissenter and say you're almost certainly going to want an adjustable gas block.

I had a feeling I was going to need one to help keep her from throwing gas back in my face. Any recommendations on brands?

Superlative Arms has one of the best AGBs, as it can be set to restrict or bleed gas as desired.

I have a Sandman-S on a PSA 10.5" pistol, and haven't changed anything on it, even the buffer. Ejection went from 4:00 to 2:00, but otherwise runs smoothly. I only notice gas when using Wolf ammo, due to the smell. Otherwise, no issues at all.

Alright cool I've been looking at the Superlative Arms one for a little and hadn't decided if I needed it. I'm thinking that and the H1 buffer and I should be ready to rock.

This +1.

Run it first as is gets my vote again.

Some guns just don't need messing with in my eyes.

 

[RangerEric]

Yep, I'm running a Superlative Arms on my suppressed 11.5", went from over-gassed to the point that it was miserable to shoot, to being super comfortable and slightly quieter. Couldn't be happier.

I'm no expert on the AR, but the SBR I put together has a 10½" barrel, and it runs fine suppressed.

All comes down to the size of the gas port, can vary quite a bit between guns.

I shoot a 10 inch barrel with a silencer and without anything fancy all the time. No problems. adjustable gas blocks only serve to relieve you of some of your ammo money.
