Description
Bag of one hundred .45 ACP blanks made specifically for the Thompson (M1928A1 & M1A1) & M3/M3A1 “Grease Gun”. We recommend a BFA aperture of ~0.160″ to get the proper gas and sound in an M1A1 Thompson.

Excellent product. 100% reliable in my 10.5” Thompson AND my 8” Grease Gun, unlike many other blanks! And shipping was fast (this time) too!
