Original U.S. WWII Thompson M1928A1 SMG Complete Parts Set with Knurled Actuator and Lyman Adjustable Sight (No Receiver)

Original Item — Extremely Limited Availability

Back in stock after many years, this is the legendary WWII-era Thompson M1928A1. For a long time, these parts sets were unavailable after supplies were completely exhausted. We are pleased to offer a very small number of early-configuration “Super Select” Thompson M1928A1 parts sets, newly acquired and in excellent overall condition.

These represent the finest M1928A1 sets we have ever offered—and quite possibly the best currently available on the market. Quantities are extremely limited and they will not last long.

This set includes all components of an M1928A1 Thompson except for the rear and center portion of the demilitarized receiver. No other parts have been modified beyond the demilitarization of the receiver.

Each Set Includes:

• Complete lower frame assembly

• Finned barrel with attached compensator, still installed in the demilitarized receiver nose, complete with foregrip mounting bar and foregrip

• Early-pattern detachable buttstock assembly (no cross bolt)

• Internal components, including:

  • M1928 bolt assembly

  • Knurled actuator

  • Brass Blish lock

  • Operating spring, guide, and buffer assembly

  • Felt breech oiler

• Small components, including:

  • Ejector

  • Rear frame latch

  • Adjustable Lyman rear sight

All metal components are in excellent condition. Some wooden furniture may show period repairs or refinishing performed prior to overseas shipment during WWII, consistent with Lend-Lease service use. As original parts were assembled as available, some sets may feature later-pattern sling swivel mounts on the foregrip and/or buttstock.

A must-have for the serious WWII Thompson collector—an exceptional opportunity to acquire a truly iconic piece of American military history.
