1x Charging Handle/ Guide Rod Assembly

Assembly: (READ NOTES BELOW BEFORE ASSEMBLY INSTRUCTIONS)

1) Remove all printed support material

2) Sand the bolt raceway and barrel channel. 

3) After sanding the barrel channel, press the barrel shank into the receiver. 

4) Install the charging handle and bolt. This is the best time to apply lubricant to the bolt and raceway. 

5) With the bolt fully forward, check to be sure the extractor matches the notch in the side of the barrel shank. If not,

slightly pull barrel outwards, twist until the extractor & notch match, then press back in. 

6) Install the trigger pack, and press in the retaining pins. 

7) Press the buffer pin though the back of the receiver.

8) Place the V Block on the barrel, and drive the bolts through the block, into the channels. Apply blue loctite beforehand.

9) Install the complete receiver assembly into a 10/22 stock/chassis. Drive the takedown screw from the bottom of the stock, 

and into the receiver. 

10) Install a compatible magazine, then function check. Be sure a round feeds from the magazine, and extracts from the chamber. 

11) Take time to dry cycle the bolt around ~ 100 times to aid in break in.
