AEM5

Spikes hsv collar on a ba .7x.7 12.5 barrel should do nicley. I made my own collar but i bet the spikes would work. Might try it for $18.

I'm sure lengths and measurements have been beaten to death, but for some reason I can't wrap my brain around this one. I'm thinking of removing the G gas block and replacing with a Spikes tapered on my SOLGW barrel. What would it need to be cut down to? Or is this a fool's errand that's going to be more of a headache with dwell time and gas port size?

G block and VG6 Epsilon for the time being while I decide what to do. And glass that's older than I am but has more than a few elk under it's belt.

My M24 suppressor from Ron Allen is essentially identical to the Ops Inc. 3rd Model which became the AE 3rd Model. Correct me if I'm off here Ron please.

@k31user

Do you still (or can you) offer this M24 suppressor by special request?

The reason I ask is because I have an M24R from Remington Defense that I'd like to pair with this suppressor (and of course, have the barrel contoured to accept said suppressor as well).

It does slide on, but it needs a step or shoulder to grab onto/seat against.

Couple of things real quick. I don't make an off the shelf M4 collar any more. If they held the diameter tolerances better, I would. For any custom collar I need to know the distance from the bare muzzle to the step, and the diameter before and after the step. 12.5 barrel works with AEM5, but if you have an A2 front sight, the bayo lug needs to be trimmed off. The 12.5 barrel pictured above would need the bayo lug trimmed, a measurement for the distance from bare muzzle to step, and the diameter just forward of the step.
