New Griffin Enhanced BCG

[alamo5000]

I?d really like to try one of their enhanced BCGs

KAK recently introduced a gas dumping BCG but it looks like it vents straight into the mag well which to me is a complete nonstarter. I have to disassemble and clean the mags I shoot suppressed with already because of how dirty they get, can?t imagine amplifying the gas and carbon on the ammo that?s about to get introduced to the chamber of the rifle

Honestly it's not that bad. Think about it for a minute. The gas and carbon coming from the barrel is the exact same. This is the majority of carbon getting in the mag. The amount of gas coming from the tube is the same. On a traditional system as soon as the gas key gets disengaged that gas and carbon goes in a 360 degree pattern everywhere in the receiver with some escaping from the ejection port.

With this new one the same amount of gas is there. It's just given a longer path to travel before it hits the open air. Looking from the shooter's position the gas goes about 1/4 the distance around the left side of the BCG before it's dumped. Instead of the gas going on the path of least resistance (which is every direction), it's given a longer dedicated path and through a pocket on the left side of the carrier.

IIRC, griffin said there?s a gas dump or gas pocket on the left side? Might be misremembering. Any issues of extra fouling on the inside of the receiver?

Yes there is a pocket and no there is not anything substantial in terms of 'extra' carbon. If there is anything additional it would be like 5% or less and that's just because of the different pathway.

I recently got a PWS long stroke piston setup that?s 11.8?. I was amazed at how much cleaner the brass is suppressed compared to my tuned DI rifles I?d love to throw one in my setup I?m using the thermal on and use it for suppressed hunting especially if the port noise is that much reduced.

I don't think it would work for a piston rifle. Also it works according to the length of the gas system. The longer the gas the more effective it is. For a shorty it's not really effective enough to be worth it.

Also, my 20? comp rifle has right at 5000 rounds through it and while the carrier is going strong, the bolt has seen better days. Just replaced the extractor spring and oring again. Maybe in another thousand or so I?ll swap in a Griffin carrier group

For a longer gas system it's literally amazing. If you get just the carrier you can keep all the rest of the stuff the same if you want to. They had the carriers on sale for like $117 bucks not long ago.
