A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.

[23] After 1945, the DShK was exported widely to other countries in the Eastern Bloc. [16] In 1946, an improved variant was produced, with a revised muzzle and feeding system.
The M110A2 is shorter than the original M110 and lighter as well at 10.5 lb (4.8 kg), which is comparable to the M110A1 SDMR's weight of 10.9 lb (4.9 kg) with no attachments save an unloaded magazine. The decreased overall length does not come at the cost of barrel length as the M110A2 still has a 20 in (510 mm) barrel. [2]
For instance, the cost of an SM-6 may vary by more than 100% depending on which version is examined, from about $4.25 million for Block I/IA to about $8.5 million in 2024 costs for Block IB. Costs in general appear to decline over time for United States weapons of the same version. [83]
