Side Plates

: Place the Left Side Plate into position and thread two ½” screws into the top through the 

Top Plate as shown in Figure 7.  Repeat for the Right Side Plate. Leave these four screws loose. Squeeze 
the side plates together against the sides of the lower receiver. When they are tight to the lower 
receiver, tighten the four ½” screws to 1 ft-lb. Screw the 8-32 x  1.5” Side Plate Support Screw into the 
Right Side Plate and all the way through into the Left Side Plate as shown in Figure 8. Tighten to 1 ft-lb.  
Do not install the ¼-20 x 1.5” Rear Takedown Screw. 

 

 

Note

: Many questions have been asked about the Side Plate Support Screw. It is used to prevent 

the side plates from flexing in when clamped in a vise. That is why both sides are threaded. 

 

Note

:  It  is  recommended  to  put  masking  tape  or  some  other  protection  over the  sides  of  the 

lower before installing the side plates. Doing so will help prevent scratches or wear.
