We recommend a lubricant be applied to the threads of
all fasteners in your stock. (Picture) We do not recommend a permanent thread locker to be used unless you know that you will never reconfigure or disassemble your stock. Permanent thread lockers can cause the aluminum threads to be permanently damaged upon removal. |

|
We have found that 50 inch pounds of torque to be the best starting point
for your action screws. You may wish to try 5 inch pound increments up and
down to tune your action to the stock. Never shoot a rifle with loose, non torque'd action screws!!! |
|
|
We recommend that you lay your stock down on a protected work surface and loose fit
the 4 Front Section Screws to the Center Section. (Picture) |
|
|
Then stand the 2 assemblies on end to allow the mating surfaces to contact
before final tightening. (Picture) |
|
| We recommend no more than 20 inch pounds of torque be applied to the 10-32 fasteners. | |
|
Loose fit the pistol grip-rear connection screws. (Picture) |

These screws are 1/4 x 20's, you will have +/- 3/4 inch of total thread engagement, tighten by hand until the parts don't move easily. No need to stand on them with a 3 foot cheater bar!! |
|
| The next part is getting the Rear Section adjusted properly. | |
|
Set the Length of Pull first. Remove the 2, 1/4 x 20 Socket Headed Cap Screws, slide the 2 parts apart until you reach the best fit for you, then insure that you have adequate clearance for your hand on the pistol grip. Tighten the same as the pistol grip connector screws, snug. |
|
|
You will find 2, 10-32 cap screws imbedded into the butt pad, use a 5/32
allen to remove and replace the pad. Note the radial drill/tap pattern.
This allows you to cant the butt pad, 8.5 and 17 degrees, Plus or Minus. Tighten the but pad screws just enough to snug the pad to its mounting block. |
|
|
Adjust the But Pad Height by placing the 2 cap screws in the appropriate holes for the best fit to you. To add or remove the optional Bag Bar, loosen the top butt pad screw 2 turns, then loosen the lower butt pad screw until the threads are disengaged with the mount, pivot the butt pad to the side. This gives you access to the bag bar screw. Note that with the Bag Bar in place you have to install your sling swivel stud on either side of the Butt Pad mount. Once again, no extension handles are required to tighten these screws, just enough to secure the parts. |
|
|
Adjust the Cheek Rest for the best location for you. Insure that when you complete the Rear Section adjustments, the bolt still has enough travel to function properly. |
|
| We have found that when you adjust for good clearance to the pistol grip that the LOP is about right and the Butt Pad is normally adjusted to be in the lowest position. | |
| Check your barreled action for ammunition, never work on your barreled action with ammunition in the rifle. | |
| When installing your barreled action, loose fit the action screws, stand the entire assembly on the butt pad, allowing the recoil lug to settle against the lug surface machined into the Center Section before applying torque. | |
| Now perform your final fit checks, action screw length, bolt function and body fit. | |
|
We have gone to great lengths to produce a system that works with
manufactured OEM tolerances, we have found a large variation in those
tolerances. YOU ARE RESPONSIBLE FOR FINAL FIT and FUNCTION CHECK. |
