$7.50 per op rod ~ Over the years, we have been sent op rods coated in cosmoline, heavy dried grease, and generally heavily soiled oil and grease when coming out of long term storage. When it is necessary, we are happy to clean op rods like this prior to repairs, but they will be subject to a cleaning charge. To avoid this fee, please make sure the rods are clean prior to shipping to us.

Return Shipping
$18.00 ~ UPS or USPS insured for $250 per op rod.  We return in the same packaging and typically using the same shipping method as op rods are received. More than one op rod may incur additional cost.

Prices are subject to change without notice.


* Guide Lug Rebuilds
For guide lug rebuilds, there will be a minimal visibly affected area of Parkerizing. When your rifle is assembled, this is visible to the very rear of the rod where the handle meets the guide lug and is from final hand finishing of the machining. There will be other areas of the Parkerizing affected, but they are to the inside toward the receiver and the very bottom toward the guide lug slot. We do not currently offer Parkerizing services.

** Remanufactured Op Rods
Remanufactured op rods are op rods which have had the original tube replaced with a new tube, then refinished, giving the appearance of a “new” rod. In most cases, these rods are not even close to being able to mount in an M1, so they require more time to properly contour. Pistons also appear to have been left oversized. As a result, completing these rods takes more work than a standard repair. These op rods will incur additional cost for gauge check, straightening and tilt test. The final fitting and tilt test to one of these rods will be $30 with another repair, or $55 as a standalone repair, even if there are multiple rods to be contoured. Sizing an oversized piston will be the same at $20 each.

The photos below provide examples to help identify remanufactured op rods. The irregular coloring just forward of the original weld adjacent to the saddle is the weld attaching the new tube. This example has been finished off smoothly in that area and reparkerized.
