With Iowa recently legalizing suppressor ownership, I have made a few purchases in the past few weeks: Dead Air Mask 22, AAC Ti-rant 9 & a SiCo Omega 30.  I was looking to purchase one more before 41f comes around and I am looking closely at the Griffin M4SD II.  Does anyone have any suggestions as to if the M4SD II would make sense based on my previous purchases and what are the pros/cons of this particular suppressor.

Thanks guys.

Great items to start your collection with!

I have an M4SD in jail right now, after comparing the M4SD with the Halo, I decided to go with the Griffin offering - so I don't think you can go wrong with the M4SD II.

I have the Griffin M4SD and the M4SDK, I think you'll enjoy your purchase.

I have an M4SDII, got it as my first can...upside is that it can fit A2 flash hiders, and A2 flash hiders are cheap!

Downside is that out of all of my Colts (7 or 8)..it only fit on 2. So while it SHOULD fit on all A2 mounts...realistically, with tolerances, it might not. Which means even though the mounts are cheap...you might need to buy a few to find one that'll fit.

Another downside is that you really should/need to shim the flash hider, and their shim kits sometimes need more shims than what comes with them to properly time things...getting it to fit on my 10.3" Colt upper w/DD RISII, for example, not only to time right but to actually be able to get it on, required more shims than what came with the kit. (it didn't go on far enough to lock it down with the shims supplied; it was a 14.5" barrel cut down by Adco. It's possible they cut it a hair too short, who knows.)

Not dealbreakers, just have your eyes open going in.

If GA would make a plain-jane A2 flashhider that's in their spec for the same prices as everyone else's generic A2 hiders...that'd be killer. Dirt cheap known compatible flash hider mounts for it that maintains a factory look for almost everything out there. But, that's just me, I could be wrong

Other than that? Wouldn't change a thing. It's quiet, not terribly heavy, locks up well, has a ton of compatible muzzle devices...it's hard to beat that. Most cans have at best a choice between one kind of flash hider or one kind of comp. Some have maybe two types of each. GA has many different models of all kinds, plus will fit on any A2 compatible hider.

It is a great can in terms of suppression and the A2 style connection compatibility. This was huge for me.

Oh don't get me wrong, I'm not "blaming" anyone - I figured my barrel was just a skosh too short, either that or the DD rail is a tiny bit longer than normal It just took me by surprise when I went to time it, got it perfect and found that the can didn't go down far enough It worked out, I bought spare shim sets just in case of something like this in the first place. This barrel was cut down by Adco; I haven't tried it on my factory Colt 10.3" mainly because that one is set up like an original Mk18...no DD RIS on it.

As for the A2 thing...that's another good reason to start cranking out your own A2s Having a non-fancy and inexpensive mount that can replace any factory A2 without upsetting a collecting purist has got to be worth something...the main reason I don't run out and buy more A2s is because I don't want to blow $10 on yet another A2 that doesn't fit. I don't need a drawer full of them I'd rather buy one I know will work, even if it costs me a couple bucks more. That way I can swap out flash hiders on a bunch of guns without it immediately looking like I did so, and still be able to take them to the range and put a can on them.

Yeah, I know it might cut into sales of other higher end products, and not really be what you're after business-wise...but I can dream
