Frost Custom Brass #3 Backbore with #2 Threaded Sleeve – Excellent Condition

For sale is a Frost Custom Brass #3 backbore with a #2 threaded sleeve, both in excellent condition. Precision-machined by Matt Frost, this modular setup offers outstanding fit, finish, and performance. The threaded sleeve system provides a secure connection while allowing quick changes between components.

Both pieces are clean, function perfectly, and show only light signs of normal use. Threads are smooth, and the plating is in excellent shape. The sleeve is currently stuck on the backbore, but should easily be separated by a knowledgeable repair tech.

A great option for players using the Frost modular system who want a versatile backbore with the convenience of the threaded sleeve design.

Condition: Excellent
Includes: Frost Custom Brass #3 backbore and #2 threaded sleeve only.
