Riley M. ★★★★★

Exactly the right part for fixing the slop in my SC4's half nut lever—the flange sleeve fit perfectly and the machining is clean. No more play when engaging the thread.

Samuel ★★★★★

Installed this on my Sieg SC4 and the fit was spot-on with the original part, no filing needed. The half nut lever now engages smoothly without any play.

Joshua ★★★★★

The machined grooves on this locating flange sleeve line up perfectly with the half nut lever on my SC4, making installation a breeze. It’s a solid, precise replacement that matches the original part #307 exactly.
