Installation Instructions RESTRICTIONS
 

1. Remove the grip screw and lock washer from the grip of your rifle. Remove the grip. Mind the spring and detent for the safety as they may bounce out as you remove the grip completely.

2. Using a 1/8" Hex wrench, screw in the tension screw from the hole exposed by removing the grip.

3. With the upper and lower installed, place enough tension on the screw to allow for a snug fit between the upper and lower. Too much tension may cause the upper and lower to be too tight making it difficult to push the rear detent pin.

5 of 5 Tension Screw February 21, 2026
Reviewer: Zeke from RGV  
This tension screw is for the Spikes Tactical Sparton Stripped Lower. The screw does have a bit of wobble but that is due to other reasons such as finish coating to the lower receiver. I did add a bit of Loctite Silver Anti-Seize Gun Grease to the threads. In addition, I would recommend also buying the AR15/AR10 Trigger Spring Kit.
