Archived [ARCHIVED THREAD] - Need advice. Adj gas block for cmmg rkm9 handguard.
Posted: 2/5/2018 3:55:51 AM EDT
10.5 sbr.  Way over gassed an will be suppressed on occasion.  I need a adj gas block that will fit under this rail with a .750 barrel.  What are you guys running that will fit under this small handguard?  Thanks for input hive.

While the CMMG webpage says it is 1.360" diameter... is that from top to bottom ? ... or from side to side ?

I'd bet the SLR Sentry 7 set screw would fit.

SLR shows the dimensions  of the .750 Adjust. GB here....

Do a little measuring on your CMMG GB and compare.

Be sure to consider buying the dimpling jig, and for sure buy a spare gas tube and roll pin.... the gas tube can be a PITA if it is sealed in the GB.

Just curious, have you tried an H3 buffer and a Wolff extra-power recoil spring?

I put together a 7.5 barrel AR in 5.56 that was throwing brass the @1 o'clock position. An H3 buffer and extra-power recoil spring have M193 ejecting at a little past 3 o'clock. However, I don't shoot this gun suppressed.

No I haven't.  It's throwing brass at 1:00 with carbine buffer.  I want to keep this right light so I want to fix it on the gas side.  That will also let me regulate it suppressed.
