Me likey…
Awesome! I run plan B from Q….. It makes swapping easy
Love your products, but why does it take 30 business days to get a muzzle device? Do y'all make them in house once an order is paid for? Only asking, not trying to be rude.
Will GMMC offer a Plan B–style muzzle device with a pin‑and‑weld hole for 14.5-inch barrels? Many of us are looking to replace our current pinned muzzle devices with suppressor‑compatible options.
Awesome 😎👍👍
👍
nice option there
sick! i cant wait to get my hands on a zeroed 30k!
This is AWESOME!
Supressors are important since the gun manufacturers convinced people they don't want a real barrel. They still those short tubes on the carbines (they aren't actual rifles any more) and people believe that's good. It is good for the manufacturer, since they save a little steel (which equals money).
This is but one of the ways they make folks think they want things which are merely money savers for the maker. But, now you need that red bull can stuck on the end due to the hellacious roar.
(ALSO, you want a short action, as working a long bolt throw is too much work for a human being to handle. More money saved. There are many more ways they have convinced folks they want less, but will pay more. P.T. Barnum was spot on.)
will be purchasing these NOW where is that handguard!! 👀😂
I love CMMG! Gotta get one for my Dissent!
Please do pin and weld plan b on 13.9 🙏 14.5 is fine too
