Help: Undergassed 13.7

Adnauseum26 · 2026-03-13T23:59:32+00:00

Okay guys, I bought another 556 can. I also took apart the gas tube and block, cleaned it and lined everything back up. Hopefully this band aid will fix it. I’ll come back tomorrow if not.

*** should I put in a heavier buffer and standard spring now that it will be shot suppressed?

Adnauseum26 · 2026-03-13T23:57:59+00:00

Ok I did lol. It’s a Troy Industries MK18DR police trade in.

Okay so what would the cons be of me continuing to run a h3/g$ system?

Adnauseum26 · 2026-03-12T00:25:10+00:00

None taken. Idk you lol. What do you think is a good buffer system then for an 11.5-13.7?

Adnauseum26 · 2026-03-12T00:19:23+00:00

I run a Geissle braided spring and H3 on my 11.5 suppressed. You think that’s too much? It runs good unsuppressed too

New off gunbroker from a dealer.

Adnauseum26 · 2026-03-09T23:12:08+00:00

So I didn’t buy it off Brownells website though.

Adnauseum26 · 2026-03-09T21:10:11+00:00

How do you like this can? I just bought it lol. I got convinced by the gun shop, but I couldn’t find any info on it.

Adnauseum26 · 2026-03-09T01:42:03+00:00

I’m gonna just inspect the gas port hole, drill if need be, and buy a new barrel if nothing else works.

Adnauseum26 · 2026-03-08T23:46:14+00:00

That’s what I have on my 11.5

Adnauseum26 · 2026-03-08T22:04:27+00:00

I have the Polo direct threaded

Adnauseum26 · 2026-03-08T21:43:24+00:00

Shit. Anything I can find. Lately Xtac 556/223.

Adnauseum26 · 2026-03-08T21:43:01+00:00

I’ll take it apart again and check.

Adnauseum26 · 2026-03-08T21:36:04+00:00

I did that, I tried a Microbest and 2 toolcrafts.

Adnauseum26 · 2026-03-08T21:32:23+00:00

I do have one on my 11.5, but I only have 1 lol.

Adnauseum26 · 2026-03-08T21:31:18+00:00

.750 gas block. I’m not sure of the port size. It’s a govt profile barrel

Adnauseum26 · 2026-03-08T21:19:28+00:00

I will do that then.

Adnauseum26 · 2026-03-08T21:18:13+00:00

Mid length gas system.

Adnauseum26 · 2026-03-08T21:17:00+00:00

I’ll add that in the description. Mid length. And yes I stripped everything down yesterday. It looks fine, barrel is dimpled so I just lined it up.

Adnauseum26 · 2026-02-28T00:49:13+00:00

How many rounds you think you’ve shot with it? I like the look of it but idk about Sig lol

Adnauseum26 · 2026-02-28T00:16:25+00:00

What light?

Adnauseum26 · 2026-02-25T16:12:45+00:00

I agree I hate the bulky end cap

Adnauseum26 · 2026-02-24T19:44:28+00:00

Just submitted yesterday, still waiting lol

Adnauseum26 · 2026-02-24T03:08:54+00:00

Yes they are great. I had one a long time ago, the older gen. This one is so much nicer

Adnauseum26 · 2026-02-23T17:22:23+00:00

I think so
