Proper torque for forend screw
« on: October 25, 2008, 05:30:47 AM »
I was wondering if anyone knows or can suggest the proper torque for the forend screw.(in lbs.) I am having trouble coming back to zero after I switch barrels on my frame. Both barrels(.204 Ruger and .280 AI) shoot good until they are changed out and then have to be sighted in again. I think if I put the forearm back to the same tightness every time it will solve this problem. The shot still group together they just aren't on zero. Hope this make sense. It's good to be back, as I have not posted in a while.

I've been using 28 in/lbs, seems to work great, it's snug. but not too tight. I think making it the same each time is the important point.

Thanks Tim, I figured you would have some input here. Do you use a screwdriver or a wrench?

I use a Utica TS-35 screwdriver, bought several in a batch for $25 a few years ago on ebay, enough to make three good ones from the parts that I can "calibrate" to the same torque with my Craftsman micro torque wrench. I keep one on my work bench, one in my range box and one in my travel Handi gun case. I also have a FAT wrench that I use for scope mounting, it would be the best buy at around $40-$50, there's a link in the FAQs on it.

Thats the biggest complaint I have w/ my survivor forend is that it is a thumb screw that can't be torqued.  So I made a dot on the screw and one on the forearm and attempt to get it back in the same snugness every time...

Not that I've ever seen or read. This is all it says in the owner's manual....

Replace the forend and be sure the forend screw is securely fastened.

i just bought a 1/4"x20 body bolt at lowes the same length as the finger screw.  it is black and already has a washer attached to it that wont come off.  the washer is also as big as the circle cut out on the survivor stock.  i locked mine down at 55 in/lbs and just mounted the scope.  got to polish the barrel and see how it shoots.  i am also planning on attaching a 10 round shell holder that comes with the ammo box to the right side of the stock to store ammo.  was looking to fab an adjustible cheek height but was able to use my low leupold rings and bushnell 2x7x32 scope.  dont like how flimsy that front stock is, may have to change it out with a choate varmit stock.

99 , I know what you mean about the Survivor forearm.  I stiffened mine up by cutting a section out of an old fiberglass fishing pole & gluing it into the void with Epoxy designed for plastic. Then I filled the remainder with insulating foam. It is much better. I also got a Varmint forearm but it has a much different feel than any of the other forearms & I'm not sure I like it.  It seems too hard, too wide, & too heavy. JMHO
I'm going to check my local Home Depot & see if I can find one of those body bolts! Good Luck   :) Jim
