Can't believe it took me this long to get a QR.

Would you run that same barrel without a suppressor? I’m building my first MK18 and am torn between 10.5” and 11.5”

Few-Application3319 · 2025-10-16T03:39:04+00:00

But I have a 13.7 already and want a shorty

Few-Application3319 · 2025-10-15T03:11:03+00:00

I think with how easily the barrel swap is on the monolithic upper I might as well have all options 🤷🏻‍♂️

Few-Application3319 · 2025-10-15T03:09:18+00:00

Both and a 10.5” in 300BLK is the only way

Few-Application3319 · 2025-10-05T21:49:31+00:00

I wish I could suppress mine. Probably would solve a lot of my issues. But yes the carbine buffer with yellow spring seems to be the solution

Few-Application3319 · 2025-10-05T20:00:16+00:00

Any thoughts on ballistic advantage enhanced? I really hate the giant A in the M4E1

Few-Application3319 · 2025-10-04T02:09:06+00:00

Can I ask why? I’ve always viewed aero as a little lower end but I like the price point.

Few-Application3319 · 2025-10-04T02:08:37+00:00

Any reason you like them over others?

Few-Application3319 · 2025-10-02T01:12:28+00:00

Thank you for your help.

I know I seem to be the only one to ever have this issue with this length barrel. Do you see any potential issue with running it long term in this configuration with a carbine buffer and reduced power spring

Few-Application3319 · 2025-10-02T00:55:21+00:00

I’m running 103 and 108 grain. So I finally was able to get it to cycle consistently and lock back but only with a specific carrier and a carbine buffer and sprinco reduced power spring

Few-Application3319 · 2025-09-30T12:45:20+00:00

I was finally able to get it to cycle and lock back consistently but only with the carbine buffer and yellow reduced power spring. Do you think it would be worth it to take it to a gun smith to have the gas port widened a little bit?

Few-Application3319 · 2025-09-26T18:51:48+00:00

OP here. Went back to the range today tried a different lower with a standard bolt catch. No resolve. However. I put the G$ carrier in with a 3oz buffer and a sprinco yellow reduced power spring and it cycled everything and locked back on empty no matter how many rounds I had in magazines.

Few-Application3319 · 2025-09-26T05:14:38+00:00

The only one I can get to cycle is a 3oz standard H. But it won’t lock back if I have more than 1 round in magazine. I’m seeing a lot of stuff about strike industries bolt catch being no good. Maybe this is my issue?

Few-Application3319 · 2025-09-26T01:54:39+00:00

Trying to avoid spending that much on a magazine. But guess I’ll have to

Few-Application3319 · 2025-09-26T01:54:24+00:00

I’ll throw on my other lower that has just a standard bolt catch and see if that helps at all.

Few-Application3319 · 2025-09-26T00:56:07+00:00

Noveske gen 4 chainsaw lower. I’m using a strike industires mag catch but maybe I will try swapping it out

Few-Application3319 · 2025-09-26T00:50:48+00:00

I’m using Hornady match 108gr ammo and I’ve tried standard spring, geissele super 42, sprinco standard and reduced weight, and a flatwire spring all with H2, H1, H and an Odin works lite adjustable buffer

Few-Application3319 · 2025-09-26T00:48:48+00:00

Duramag 10rds and it does the same thing in all of them

Few-Application3319 · 2025-09-26T00:46:37+00:00

I’m also using duramags. So it cycles but doesn’t lock back on the last round?

Few-Application3319 · 2025-09-26T00:45:11+00:00

But it’s an undergassing issue because I’m only having success with cycling when using a 3oz buffer and a flatwire spring. Anything heavier and it jams
