Another first from Trollwerks... This Harlot family breech block has been modified to use a thick M4 washer as reinforcement instead of a drilled dime or no dime. It is the correct breech block upgrade to use for the following Trollwerks kits: Harlot V2, Shizukana, Brawler, Brass-Brawler, Brasstax, LongShot, Artillery Boi, Quiet Girl, etc. as well as most Harlot-family builds that use the center drilled dimes as reinforcement. The M4 thick washer is cheaper and easier to use, and helps us keep the costs and wait times low and production high. After drilling some 500+ dimes, I'm wondering why I didn't think of this sooner! Enjoy! NOTE: Must use ONE (1x) 1.4-1.8mm THICK M4 washer, OR 1.5-2x thin 0.7-0.9mm (normal) washers. Harlet / Harlot V3 builders see my other post specifically for those.
