NEW Centurion Arms C4 m-lok rail

[TommyG]

These are f***ing clutch.

I’ve always liked the C4 rail as a future upgrade for FSB equipped rifles. Cut the delta ring assembly and handguard cap off and bolt the handguard on. No messing with BCM or LMT’s insane pins to remove.

But they only had pic rails which are needlessly heavy. I absolutely plan on getting one.

Yup, sold. Have been slooooooowly transitioning from pic to M Lok. The FSB rifles don't have to be hold outs any longer. Love he 12 inch with the FSB cutout.

Got one, and installed it!

I’ve got an original on my home defense rifle. Wonder if this’ll fit in the new BCM mk2 upper. I’ve finally decided MLOK is here to stay, and will probably swap out at some point for the improved grip.

Centurion seems determined to separate me from my money.

Thanks, Stick! That looks way more functional than I anticipated.

Thanks for the pic. Looking forward to getting my paws on one.

Not only that, but it is so light weight it doesn't seem to offset the balance and handling like the RIS II and other rails do. Don't get me wrong, I love my RIS II rails, and own a pile, but this is a different beast.

This jives.

According to Centurion's website, it weighs 9.8 oz. Using the AR parts weight database, an OEM Colt double-shielded handguard plus the delta ring assembly and handguard cap weigh in at... 9.8 oz!

Have to say this is the first M-Lok rail I've seen that I actually like (have always preferred picatiny rails). Will definitely be using one or more of these in the future.
