Any of you have experience with them? I found a Drakon for $80 and the M4-72 is similar in price.
I've used the M4-72 before on an AR but I recall it sent a lot of gas back and with AK ammo being so dirty... I dunno.

I'd like to try the PA M4. I was unimpressed with the 556 Lantac. The Manticore is not in the same league.

I've heard people compare the Manticore Nightbrake to the much more expensive AK Battle Comp in terms of performance.
I don't have an AKBC to compare my Nightbrake to however, but I'd say it's pretty effective.

There are lots of options out there now for AK muzzle devices, but frankly, some of the cheapest perform the best, like the Tapco slot brake for around $14.

Here are some of the Manticore options being tested on a full auto M92 SBR:
