If you need a shorter length-of-pull this is the product for you.

By replacing your standard adapter block with this you decrease the length of pull by this much:

Sig sauer adapter block: 23mm/0.9in

Standard adapter block v1 (every mid section delivered to 01.08.22): 23mm/0.9in

Standard adapter block v2 (every mid section (except sig sauer) delivered after 01.08.22): 16mm/0.62in

As with all of our products this comes with black stainless steel torx screws so you don’t have to worry about corrosion.
