ATI Strike Force. Like getting an instant bedding job for your Mini-14. Pull your action out of the old stock, put it in the new one. It's a tight fit, but it works great, especially if you have more than one person shooting it. Length of pull is adjustable, and the cheek rest is adjustable for open sights or optics. I'm really happy with mine.
ATI is a drop in. You'd have to modify if you had a Mini-30 or the 6.8SPC model. Between that and the muzzle brake, I went from 6" groups to 1.5" groups @ 100 yds with my older Mini. I'm picking another one up when I can get the cash again for my newer Mini.
What is the best after market pistol grip stocks for the Mini 14?
I have a Butler Creek folding and it fits great but I dont use it for hunting I use the original stock bedded in and spot bedded the barrel and taped the rear and secured the action to the stock I can pick it up and never worry about where its going to hit.
