Description
Eliminate the annoying play between your upper and lower receiver with this simple but effective Tuning Tension Wedge.
Designed specifically for the SIG SG 550 series (550, 551, 553), PE 90, and Stgw 90, this insert removes the "slop" or rattle that can develop between the receiver halves over time. By applying slight pressure, it ensures a rock-solid, monolithic feel to your rifle.
Key Features:
- Removes Receiver Wobble: Tightens the fit between upper and lower receivers instantly.
- Improved Handling: Makes the rifle feel like a single solid unit, reducing distraction and noise from loose parts.
- Wide Compatibility: Fits the entire SG 55x family (550, 551, 552, 553) and civilian PE90 / Stgw 90 models.
- Non-Permanent Modification: Simply drop it in—no drilling or permanent changes to your rifle required.
Installation: Place the wedge inside the lower receiver before closing the upper. The wedge buffers the gap and creates a tight lock-up.
