Can I ask one question about how fast is fast. The question is loading the shotgun the only thing in the match. Seams like a dump question but the last time I shot THREE GUN it was with three guns just not the shotgun only so load as fast as you can go and done miss. Why I say this is because everyone thinks loading a SHOTGUN wins the match. If that was true Daniel Horner would never win a match.
I know it's not on your list, but if the new version will survive, the Cmore RTS is awesome. I don't like any slide mount optics.
problem I can't find a mount for it (xdm).
You can't find them in stock anywhere
Hell, I can drop three or four shells in under a min. and make Kurt smile as I am doing it . But I can shot one for one went the dam beeper goes off. Shoot small miss small.
So with this line of thinking I should stop shooting my Rock River at the 3gun matches because they don't support. Man is that closed minded. Shoot what you want to shoot.
The people paying that much for pmags are the ones that dons't need a AR-15. People who use there AR's have the mags we need so let the dump butts pay 70.00 dollars for them.Just my two cents
