I'm pretty tired of getting all the gas back in the face when shooting the suppressed mousegun.

Got one on mine. They help a ton with a suppresor.

Gonna move this to the correct forum.

Thanks!

How does the bigger latch stop blowback? Is there some sort of seal on it?

I have one upper with ATV sealant on the charging handle that creates a seal between the handle and the upper and another with half an o-ring superglued to the charging handle to accomplish the same.

I think there needs to be something there to stop gas from escaping between the two.

As a self taught builder I have yet to encounter this problem. Is it a lefty thing? It might indicate that there is a problem with your gas system. Key to gas tube make up? Loose key? If so, it seems to me that gas buster is treating the symptom.
But hey, they make em for a reason right?

Like Correia said, it helps with the increased backpressure when using a suppressor.

note to self: might need one when I incorperate

it's not a lefty thing, but if you are lefty, don't get the gasbuster.

I have them on my carbine length ARs. I am a lefty. The latch itself is thicker, and has a port on the underside which helps direct gas out the right side of the gun rather than have it all go backward.

I never had a problem with normal charging handles, and don't have any problems with these. I got them in anticipation of suppressing these guns one day.

I have shot suppressed guns with normal charging handles, and did experience a little blowback that would be nice if it were eliminated, but nothing really uncomfortable. I have not shot a suppressed gun with the Gasbuster, so I can't speak to its effectiveness for its intended purpose at this time. If nothing else, it is a top quality built unit, and the bigger latch is nice in any event.

most shooters put their nose on or near the charging handle. if your gun doesn't vent any gas back there, you don't need a gas buster. if it does vent gas, it will vent it right next to your nose. Plan on holding your breath while you shoot and scrubbing your face afterwards.

You can make your own with some black silicone.

I have a PRI Gasbuster, an OPS Inc. 16th model suppressor and I shoot nose-to-charging handle. The Gasbuster will mitigate gas in the face from a suppressor but it does not eliminate it entirely.

If you don't have a suppressor, the main thing it offers is a nice, solidly built charging handle that is easy to get a hold of and easy to cycle. You can get a lot of what the Gasbuster offers in easy manipulation by buying the PRI Big Latch for $20 and installing it on a regular charging handle. I do like the Gasbuster though because I find it a tad easier to manipulate quickly.

sorry if that wasn't clear bart, but my post was specific to shooting left-handed where the gas exits into your nose, as opposed to right handed where it directs it away

 

[Bartholomew Roberts]

Didn't even notice the comment, taliv. I have not shot my rifle with the suppressor on and left-handed so I couldn't comment in any case. I do shoot it left handed without the suppressor and haven't noticed any difference; but I am still working on a good, habitual cheekweld for left-handed shooting too.

And unfortunately, with your nose up against the charging handle, the gas blows up & under your shooting glasses, making them almost useless! I wear contacts, and after shooting every SR match, I can feel "grit" in my eyes when I get home, from this phenomenon. (FYI, I use a fairly new WOA upper, and the key is tight).
