Sinclair O-Ring Rod Guide, 338 Ultra Mag | Sinclair Intl

Our Centerfire Cleaning Rod Guides are designed to insert into your action In place of your bolt or bolt carrier. They feature a snout with a silicone ""O""-ring that inserts into your chamber, sealing the barrel off from the receiver. The ""O""-ring prevents solvents from leaking back into the action area and gumming up the trigger assembly. We currently stock ""O""-ring rod guides for over 1000 different action/cartridge combinations. Each rod guide is machined to fit specific actions and cartridge families from .17 up to .338 caliber. Unfortunately some rifle chamberings do not lend themselves to an ""O""-ring style rod guide, for these cartridges we recommend one of our Adjustable Cone Style Rod Guides.

In an effort to better serve the cleaning needs of our customers, we have upgraded our Sinclair ""O""-ring rod guides to include integral solvent ports. This upgrade is now included with every centerfire bolt action rod guide and nearly all AR style rod guides. If you prefer a rod guide without an integral solvent port, please contact us via e-mail or phone and we will happily provide you with a rod guide to your liking. These rod guides without solvent ports will be treated as semi-custom, so please allow 2-4 weeks for delivery of rod guides without solvent ports. There is no additional charge for rod guides without integral solvent ports.

If we do not inventory a rod guide for your specific action/cartridge combination, we can probably make it. These non-inventoried rod guides are considered custom rod guides and are a few dollars extra, please allow 4-6 weeks for custom rod guides.

Will fit the following Actions: Borden Rimrock, COOPER 54 & 22,COOPER 16(WSSM), BRNO, Browning A-Bolt, CPS,Dakota Arms Model 76, GA Precision Templar, Stiller Viper, Enfield Model 1917, Grunig Elmiger, Hart, Herter Model V9, Husqvarna Model HVA & M8000,HS Precision, Mauser Model 3000, Mauser 38 Swedish Target, Mauser 98 type, McMillan Signature, Remington (all 700,600 &7), Ruger Model 77 short and 77 long, S & W Model 1970,  Savage 110, 112,11,12, Springfield 03A3, Stolle (all), Tanner, Weatherby, Varmitmaster, and Winchester (pre 2010 FN production).

SPECIAL NOTE: FN versions of the Model 70 do not all have .700 bolt diameters. Also they have FIXED ejectors so a slot has to be milled down the length of the rod guide body. So any Model 70 made after 2010 that has FN and not Winchester New Haven Connecticut stamped on the receiver is now a CUSTOM ROD GUIDE and you have to check the bolt diameter.
