Thompson Leaf Sight Slide

Features

1. Direct Replacement Part — Drop-in slide component for the Lyman-style adjustable leaf rear sight assembly used on the Thompson submachine gun.
2. Elevation Adjustment — Functions as the moving element of the leaf sight, allowing the shooter to dial elevation up or down across the sight's calibrated range.
3. Built to Original Specifications — Reproduced from the original Lyman pattern so it indexes, slides, and locks the way the factory part does.
4. Steel Construction — Machined from steel for durability under repeated adjustment and the recoil cycle of the .45 ACP Thompson platform.
5. Thompson SMG Compatibility — Fits the leaf sight assembly found on the M1928, M1928A1, and other Thompson variants equipped with the Lyman adjustable rear sight.
6. Restoration-Grade Spare — A sensible addition to any Thompson parts kit, restoration project, or collector's spares drawer where the original slide is missing, worn, or damaged.
7. Compact Wear Item — Sized as a small, frequently-cycled component, this is exactly the type of part worth keeping on the bench before you actually need one.
