SMART PARTS FREAK XL BOREMASTER KIT - STAINLESS STEEL
Smart Parts Freak XL Boremaster Kit
Contains 8 Freak XL Barrel Inserts
The Freak XL inserts offer a full 8-inch control bore which is expertly honed from stainless steel and available in a complete range of bore sizes: .679, .682, .684, .687, .689, .691, .693, and .695. Like the original Freak, Freak XL inserts are color-coded with a durable low-friction finish and laser engraved for quick identification.
I will start by saying I am not completely sold on these yet. The theory sounds good, but the practicality is questionable. Paint size varies and different sizing can help. With that said, the paint varies within the bag so you always need to bore up a bit anyways. I only ever use a couple of inserts, but I don’t travel around to different places. With all that said, the aluminum is sturdy but the SS is stronger. It is also much heavier. Aluminum .687 is 21.3 grams and the SS .687 is 63.4 grams. That’s less than two ounces, but plenty of equipment is advertised as better because of less weight than that. In the end, durability was more important to me. Case is great.
