Shipment to FFL required
Please provide FFL information in the “shipping address” or order notes/commentssection while checking out.
Due to BATFE complications that started in July 2018 we halted production till we could receive an official determination for our SHTF50 upper conversions. Long story short, they determined that our SHTF50 upper assemblies constitute a “receiver” of a firearm. This means that all SHTF50 upper assemblies, from this point on, need to transfer through a FFL dealer.
The SHTF 50 single shot upper assembly utilizes any standard AR15 to make a .50 Caliber Bolt Action rifle. The SHTF 50 is designed to fit any mil.spec AR15 pattern lower. The SHTF50 is available in 3 different barrel lengths:
18″, 22″, and 29″. Note: AR-15 lower NOT included.
Starting at $1850.00
Single shot SHTF50
One(1) hammer and spring to replace the AR-15 hammer and spring
