All .20 Caliber Nylon Coated Rods have 5/40 Female Threads, an outside diameter of approximately .185 inches, and a dual track ball bearing handle. The Nylon will not peel or pick up abrasives of any kind. All rods are single piece rods unless otherwise stated. We recommend this diameter rod for cleaning .22 rimfire rifles as those barrels are very tight and .22 caliber rods can at times be too large to pass through them freely.
Be Aware: TM solution by Sinclair International and Montana X-Treme Solutions has been found to attack the nylon coating of our coated rods. We strongly recommend not using these solution with our coated rods.
If you plan on using these cleaners, please use the brass or stainless steel rods. Thank you.
