Could you define mk4? If you mean the M4 carbine, currently used by the US Military, it is about 2900 fps. If you mean the .303 caliber #4Mk1 used by British forces in WW II, it is about 2441 fps.
100-1000 USD depending on specifics
Im not sure about the first question, but yes u would need a licence for it if u wanted to stay legit. ,<<<<<new answer>>>>>>> The model ASI Paratrooper and the Gamo Gamatic 85 are the same rifle. Just different name. The muzzle velocity is rated at 560 FPS.
!. Keep your finger OUT of the trigger guard. 2. Point the muzzle in a safe direction 3. Check that the rifle is not loaded. If you are using the term receive as in a transfer of property, check the serial number to see that it matches that on the transfer documents.

Boss is a muzzle brake vibration controlling device attached to the end of a rifle. The BOSS system is proprietary to Browning Firearms Company. The purpose is twofold: 1./ Help to reduce recoil with the muzzle brake. 2./ Using a dialing system ( incremental numbers on the BOSS) you can set the ammount of vibration to the barrel for each ammunition load you use. This when used properly is suposed to greatly tighten the shot group on a target.

The most powerful in terms of muzzle energy is probably the .950 JDJ. The rifle weighs 80-120 lbs and even with ports and an 18 lb muzzle break with 4 mercury recoil reducers the gun still has 200+ ft lbs of recoil. .950 JDJ 3,600 grain 2,200 fps 38,000 ft lbs of energy. The most powerful shoulder fired cartridge is the 700 Nitro Express with a 20 lb rifle and still 160-200+ ft lbs of recoil. 700 Nitro Express 1,000 grain 2,000-2,600 fps 8,900-15,500 ft lbs of muzzle energy. The most powerful sporting rifle/cartridge also goes to the 700 Nitro Express. If you count black powder elephant rifles as sporting cartridges then its the 2 bore with its 1.32 in. muzzle diameter and its low muzzle velocity keeps it virtually painless and yet kicks slightly more than the 700 Nitro express. S&H 2 bore 3,600 grain 1,500 fps 17,000 ft lbs
There are 2 ABS sensors. On the front brakes only.
IF the gun meets the OTHER length requirement (26 inches minimum in firing condition) AND if the brake is permanently attached- welding or silver soldering- then yes. If it can be unscrewed, no, unless a Class II NFA permit for a Short Barreled Rifle is obtained for it.
Make sure that MK3 is 5 stud as they have 2 different stud patterns - 4x100 and 5x100. Mk4 is 5x100 pcd (bolt pattern). So make sure you have the correct fitment.

DEPENDS ON which RIFLE, AND which BULLET. A standard velocity .22 Short has a muzzle velocity of about 1100-1200 feet per second. At the other end of the range, I have a .220 Swift (high powered, bottleneck, centerfire cartridge) that fires a bullet at about 4,200 ft per second. MOST of the others are somewhere between those 2 extremes.
