Northwest Precision Muzzle Brakes p roudly made by Mac's Gunworks in Gillette Wyoming USA Custom contoured to your specification, keep reading to find out how this works!! These NWP Muzzle Brakes are designed by certified master gunsmith Chuck McIntosh. These are the very same muzzle brakes Chuck uses when building his long range tactical rifles and pistols. Find us on the web or Facebook to check out the gallery of customer gun builds using these muzzle brakes, we are Mac's Gunworks in Gillette Wyoming. We finish these NWP brakes as they are ordered. The NWP brakes are threaded, crowned, bored to your caliber, and optionally contoured, leaving you or your gunsmith final fitting as well as the opportunity to turn a seamless transition from barrel to brake. We will custom contour the rear of the brake to your specification, for example: Let's say you have a 6.5mm Creedmore with muzzle diameter .750" and 5/8-24 threads. We can contour the NWP brake from .750" muzzle diameter to the larger brake diameter, most often .850". See listing photo's for examples of what this looks like.
See below how to order your custom contoured brake! -and the size limits. FAQ: Our NWP Muzzle Brakes must be indexed to your barrel. These high performance NWP brakes have muzzle jump reduction ports at 12 o'clock, and recoil reduction ports at 3&9 o'clock. Our NWP brakes have no ports on the bottom side. (bottom ports kick up dust and negate muzzle jump reduction ports.) FAQ: Our NWP Muzzle Brakes can be indexed without washers or shims by you or your gunsmith if you have a metal cutting lathe. This involves facing off slight amounts until the brake tightens up at the right index. This is how we install them here at Mac's Gunworks every day. FAQ: Our NWP Muzzle Brake can be indexed with washers or shims and there is a huge variety of styles and materials to choose from on Pricetronic -which is where we buy them when needed. FAQ: This NWP Muzzle Brake will come Cerakoted Black. Three other finishes are available "polished stainless" which means belt sanded while in the lathe. We will also media blast ( non-shiny) or bead blast the brake for a non-shiny finish. Please see listing photo's for example of both finishes side by side. Very important: Please let us know using the special instruction dialog box when ordering, the caliber, muzzle brake outer diameter, mounting thread, and contour diameter if using the custom contour option. For example: . 300 win mag x .950 OD x 5/8-24 x custom contour from .800" (I encourage you to copy, paste, & edit the above example into the special instructions dialog when ordering.) (Please!!)
