Standard kits called AR MR2 are sold all over the internet,Amazon, etc, they convert an AR into a top loader, however the kit does not fit HK416 22 lr, pins are too large, bullet button is a whole different game, I'd rather you google it than me type a lengthy explanation, although I recently discovered a bullet button offered for the 416 22lr pistol, maybe that will work, clock ticking here in NY
Hey all, Im in one of the oppressive states and have to be compliant soon, need to make my 416 22lr to have a non detachable magazine, looks like standard buttons do not fit/function properly, anyone have ideas or where to purchase something to work
