Fine threaded systems intended for hand tightening typically use thread pitches around 1 mm (25.4 TPI). Many older rifles from the first half of the 20th century use a thread pitch around 2 mm (12.7 TPI), while many modern rifle use thread pitches around 1.5 mm (16.93 TPI). Typically, many rifles use thread diameters in the range between 25–27 mm (0.98–1.06 in). However, the use of action threads is not well standardized within the firearms industry, and threading can vary between manufacturers and models.įor example, factory and aftermarket receivers using the Remington 700 footprint are produced with various types of action threads, all with a 26.99 mm ( 1 + 1⁄ 16 in) diameter, but with a pitch of either a 1.588 mm (16 TPI, Remington standard), 1.411 mm (18 TPI) or 1.270 mm (20 TPI, Savage standard). Threading can be specified by diameter, pitch, angle, length and fit tolerances. There are many systems for designating thread types ( metric, unified, Whitworth, etc.). Muzzle threads are situated at the muzzle end of the barrel and can be used for mounting accessories such as a flash hider, suppressor or muzzle brake (compensator).
Furthermore, recoil-operated firearm designs have moving barrels (e.g. Action threads are not the only method of fixing a barrel to a receiver (see Alternative methods below). This method of fixing a barrel to a receiver has been used extensively by firearms manufacturers since before the 20th century, and can be viewed as a traditional barrel mounting method. This design is most commonly used in rifles and revolvers, but also on some pistols and shotguns. The receiver normally has corresponding threads which are internal, with the matching action threads on the barrel usually being external threads. In firearms, barrel threads refer to the screw threads used to attach a barrel.Īction threads, also called receiver threads, are situated at the chamber end of the barrel, and can be used for attaching the barrel to the receiver. This 5-Port Monster is built to tame the large magnums as well as the smaller competition rifles with large diameter barrels up to Straight 1.Method to attach a weapon barrel and receiver Identical to the Original Heathen with the addition of an extra port making the Heathen even more effective! It works very well contours from Heavy Palma to MTU & Heavy Varmint. This Brake is the original design that raised the standard for a brake that reduces recoil, muzzle jump and blast directed toward the shooter. It best suits contours from medium Palma to MTU.
This Heathen was made to fit medium-weight barrels such as those found on the Ruger Precision Rifle, Sako TRG, Remington Sendero. We have designed 3 different diameter Heathen brakes to fit your barrel properly:Ī scaled-down version of our original Heathen brake to fit lighter weight barrel profiles #2, #3, #4 for hunting rifles and various semi-auto rifles ie. Small flat machined on the bottom face allowing the use of a level to indexĬhoosing the correct size brake diameter:.Caliber and Thread Specification inscribed.The Heathen is Liquid Nitride treated for an incredibly smooth, hard and wear-resistant finish.

This brake uses a knurled nut to allow the user to install and index the brake without tools. Additional inserts in various calibres are available in the drop-down list of brake options by selecting ‘thread Specification’:” NA” Each Hybrid comes with a tool to change the insert. The Hybrid utilizes a calibre-specific insert allowing the shooter to change the through-hole size to the desired calibre.
