The SureFire developed a patent-pending Flash Hiders design with three prongs to diminish muzzle flash. The used materials (precision machined stainless steel bar stock) with a black Ionbond DLC coating ensure convenient protection under severe environmental conditions. This flash hider with a hole on it for pin and welding is outfitted with a rear seal, which reduces potential carbon buildup in the indexing system and makes suppressor removal easier after the long shooting. While installation of many 7.62 mm rifles with 5/8-24 muzzle threads any modification isn’t necessary. The device includes the Spacer Kit (Shim), Rock-sett, and tread-lock installation instructions. These flash muzzles are good for low or limited-light conditions in team environments.

The six models of stainless steel (HRC 26-32, HTSR 416) muzzle brakes are available with DLC matte black or Stainless steel in the white and matte finish. These Muzzle Brakes are outfitted with two compensated front baffles and symmetrical blast ones to redirect the rifles’ gas to the upward and sides, mitigating recoil, muzzle rise, and ground disturbance, improving accuracy.

FAQ

Should I put a muzzle brake on my 300 win mag?
After putting a muzzle brake on the 300 win mag, it’s more convenient to shoot a rifle and spot hits at distant ranges, providing less felt recoil and upward and side-to-side movement. If you don’t mind an extra noise, the brake on the 300 win mag is worth it, but anyway, use ear protection.
How bad is the recoil on a 300 win mag?
A .300 Winchester has recoil about 30% more than .30-06 Springfield. The .300 Winchester Magnum with an average load delivers nearly 30 foot-pounds of recoil power.
How far can a 300 win mag shoot accurately?

Does a muzzle brake affect velocity?
After assembling a muzzle brake on the rifle, it additionally extends the barrel and does not decrease muzzle velocity. Many snipers put muzzle brakes or flash suppressors on the present rifles. The main task of these devices is to improve the overall performance of the weapon: to minimize flash to near zero and recoil, to capture and retard muzzle gases.
Does muzzle brake affect accuracy?
Muzzle brakes don’t impact the rifle accuracy directly. After the bullets have left the barrel, the muzzle brakes allow it to diminish recoil, changing the way the barrel whips, as a result, bullets can move at a different point.
Can a muzzle brake change your point of impact?
Muzzle devices can alter the POI because of the weight loss on the barrel end, and influencing the barrel “harmonics”. A thread protector of the same weight with the muzzle brake can be made and screwed on the barrel end to hit the same POI.

My love of guns is in my blood, since childhood I have spent hours enjoying the beauty of guns and adored going through their parts.

Tactical accessories are another passion of mine that I could write about endlessly - my house and garage are full of tactical gadgets, luckily my family shares my interests.

I'm infatuated with traveling that's why work at one place with a daily routine and standard schedule is not for me. I prefer copywriting and English tutoring as a freelancer. I live in a male family among constant talks about cars, guns, hunting, fishing, and, of course, dinosaurs 😊.

My husband is an obsessed hunter, and my two sons are fans of «Demolition Ranch» of YouTube blogger Matt Carriker. They are my best consultants about weapon and all-around ammunition topics. All together we share a love for adventures. Every camping or mounting hiking trip is a "small survival", giving irreplaceable experiences. Nothing can be better than the satisfaction of observing wild nature.

Motto: «Born in Ukraine, made is the USA».
