@Les Pepperoni was gracious enough to Karma these off. But they don’t work with an MP-15/22 and I missed that post in his Karma thread. So they’re back up for Karma. Post if you’re interested. From what I just looked at they should work with any Umarex made .22 rifle like the 416/416 Pistol/Colt M4.
They’re 30 rounders so only post if I can legally send them to ya.
We’ll give this a week.
