I've got a Maverick 88 that I'm considering adding an Adaptive Technologies Drum kit to or maybe even the Black Aces receiver swap, so I can use Saiga mags. I realize that this will change the balance of the gun and make it a heavy beast. But who doesn't love a drum fed pump gun I'd like to hear feedback from folks who've used the new AT product, or even the older Knoxx Sidewinder kits (I've heard the new AT are much more reliable). Thanks, GregB Wanna kill these ads? We can help!
