One (1) BossArms 10/22 SS-Pro Maxi Shim Kit with complete easy to follow Instructions, all packaged. Works with all Ruger 10/22 family of rifles with factory made trigger assemblies; plus most aftermarket Trigger assemblies. BossArms’ SS-Pro Maxi Shim Kit comes packaged as one complete Kit:

Two Shims .010
Two Shims .005

Complete and easy to follow install instructions. Simplest means of truing-up most Trigger Assembly components, and easy too.

Designed for the Ruger 10/22 Long Rifle and 10/22 Magnums, .17’s; a means of managing precision tolerances between Hammer and Hammer Bushings; which greatly improves sensitivity to felt Trigger pull and locking time.

Absolutely a perfect match between Bushing and Hammer sides; Boss Arms Maxi Shims are made to exactly fit the “Hammer Bushing” and not hang off due to being made for some industrial usage. Boss Arms Maxi Shims fit perfectly—100%. Factory “Trigger Assemblies” have excess space between the Hammer and “inside walls” of the assembly, extremely loose fitting.

Boss Arms Maxi Shims are “micro sized” to move the Hammer Bushings away from both sides of Hammer, eliminating the excess spacing. Virtually does away with “Hammer Wobble” and “Hammer to Sear Mismatch”, also perfectly aligns the Bolt Release which ceases the customary binding with Mag Release.
