KNOXX (Owned by Blackhawk) have introduced a tactical style stock for the Ruger 10/22 rifle called the Axiom R/F. My guess is that the R/F stands for RimFire.
As you can see in the photo, the stock features a 6-position M4 style adjustable stock, pistol grip and free floating barrel channel. The MSRP is $99.99
I think this is going to be a *very* popular product. I think the price is good and it has been build for accuracy. Rimfire rifle tactical stocks tend to be build for looks not function.
