Over Barrel vs End of Barrel Suppressor

[mtnbound]

I have some direct thread cans and some OTB styles from AB and Griffin, and I prefer the balance and shorter overall length of the OTB styles.

Man, that’s sounds awesome at first glance for my polo k but needing the OPS inc collar adapter thingy in addition to the reflex is a bummer.

Yeah, so basically it’s $400 and a bunch of weight with the adapter and reflex and I wonder how much benefit it actually provides.

User of an AB 10 stack w/ 3” reflex here on a 338 wm. I love it. My experience with other suppressors are a TBAC Dominus on a 308 win and Scythe on a 6 CM. I feel the reduced recoil impulse is the most significant difference. I think it’s the large volume chamber in the reflex before the first baffle that attenuates the impulse so well.

The OP is correct, in NZ all the suppressors are OTB, and much cheaper than here. I’ve been trying to figure out what OTB isn’t common here because from my experience they work great.

Check out these guys, mana factored in NZ. Hardyrifle.com

The compact suppressor only extends 3” past the barrel end, weighs 10 oz and costs $320 usd.

Seems like a huge opportunity here for hunting rifles, and are almost std fitment by hunters in NZ.

Here in NZ I use both overbarrel and baffle forward designs. My experience is the baffle forward is quieter, but at added length.

Advantage of the overbarrel in NZ designs is that they often have two points of contact at the muzzle thread and a Delrin bushing machined to the diameter of the barrel where it slips over at the end. This in theory may make it harder to knock out of alignment if it takes a hard hit. In practice, it may not matter.

One possible disadvantage of the overbarrel is if you are doing high rates of fire it holds more heat in the 3-5" of the barrel it covers towards the muzzle. I'd be concerned about possible change of impact with the changes to the barrel and suppressor as the heat builds up. On a hunting rifle doing short strings I've never noticed any issues. If I was doing very high rates of fire I'd be more concerned and opt for muzzle forward.

Suppressors are cheap in NZ because you can buy them over the counter and they are not a novelty like in the US. They are viewed as disposable items like the barrel of the rifle. Although some makers like DPT you can replace all the baffles if needed, clean it, make longer, shorter, etc.

Banning suppressors for gun safety is akin to banning mufflers on cars to protect pedestrians against getting run over. Hopefully the US gets rid of the law so all shooters can protect their hearing.
