How to remove 640 stock?
« on: January 07, 2010, 10:04:24 PM »
Have GRT III in hot little hand.  But ... there's a mounting screw hidden under those little dark gray grips on the forward part of the stock.  Do the gray grips just pop off?  Thought I'd ask before I wrecked anything.

Got 'em.  I'd been storing the gun in the garage where it's nearly freezing, so with your caution about ripping the tips in mind I let it come up to room temp first, but then they popped off very nicely.  Thanks.  Trigger's installed, and can't wait for daylight to adjust it and start shooting!

I ripped off one of those plugs, when I plied open those forward grips on my Viper the first time I needed to get to those screws.

Ouch.  Easy does it, that's for sure.
