Great features, big improvement from the factory stock - Adaptive Tactical TAC-Hammer RM4 Ruger 10/22 Collapsible Rifle Stock

The RM4 has some good features, like the telescoping stock and integrated magazine holder. It's also worth noting that it allows you to skip the barrel band. The foregrip also feels better than the slippery factory stock.

One thing to note: It can be a tight fit when mounting to the rifle. It may take a few tries to get the takedown screw to dig in. But it'll eventually go.
