Has anybody run this through their RFB? They claim it will cycle any AR-style .308 rifle off-the-shelf. I have seen nothing about this ammo in relation to the RFB.

He says it needs an suppressor in order to work. Not sure if a low back-pressure suppressor [such as an OSS] would also make it not cycle.

This stuff is pricey; at $3 per shot...some may be able to justify it by saying it is $1.50 per bullet.

I'm hoping somebody just hasn't tried it yet, because withholding this information is a cardinal sin. Let's see what you think it will do.

Also, if nobody has tried it, I'd like to see if something can be arranged so that it can be tested. I'm not the person to do it as I have no camera appeal and am unfamiliar with this weapon system. And because this has the potential to change what we all thought possible, I'm willing to donate a box in the pursuit of science.

I received a response from their "sales" department.

Yes our 2 Hole ammunition line should cycle your rifle. It was designed for rifles like this using the 2 projectiles to push more gas.
I will give it a go when I get my tax stamp for my suppressor. ATF just cashed my check, so it will still be awhile.

As soon as anyone tests this in a Kel-tec RFB (18 or 24) or finds such a test/review/video, please post and/or link here.

Thank you
