Installation instructions

Please note: It's crucial to test and verify compatibility before using in competition settings, especially with 140mm/170mm magazine configurations. Variances can occur between mass-produced magazines, particularly in the magazine lips connecting with the extension/basepad.

Due to design variations, Springer Precision cannot guarantee compatibility with any other manufacturer’s aftermarket magwell, unless otherwise specified.
