So Redwolf just announced they got the Marui today!

Yes you can.

Maybe with some heavy modifications. A stock Rem 870 cannot slamfire.

Anyone know the fps on GG/propane yet? Im reluctant to order one till i see its over 366 lol

Hard part is mesuring fps on multi bb shot, i doubt it will be over 366 fps in any case, TM are around 280. I recall a test done on multi shot with gel to measure penetration a while ago.

Found it:

I can think of a way to measure a single BB output from a burst. But... would need the gun in hand to see if it can be done.

Can you shoot only one round with the shell? Ie you load one round only in the 30 rounds shell. Crony could read that

That wouldn't give a proper reading.

You're better off shielding two of the barrels so that the rounds and gas eject properly, so that the rounds are re-directed. Focus just one barrel through the chrony

Indeed! You would "block" the other barrel?

So how is CBSA gonna view these things. How will they test?
Guess ill either have to take a chance or get butt raped with markup

No... not a block, because that would affect output to the single open barrel. I would just redirect the shots from those barrels.
