The Colt AR-15 SP1 is primarily designed for .223 Remington cartridges. While it can safely chamber and fire some 5.56 NATO rounds, it is not recommended due to potential differences in chamber dimensions and pressure levels. Using 5.56 NATO in an AR-15 SP1 may lead to increased wear or safety issues, so it's best to stick with .223 Remington ammunition to ensure safe operation. Always consult the manufacturer's guidelines for specific recommendations.
if it is a 223 cal, then yes
Yes it does, unless your barrel is stamped .223 .
Yes. The Marlin model 556 is a bolt action shotgun. It has a detachable magazine which holds two rounds and one round in the pipe for a total of three rounds. It is able to shoot 3 inch ammunition.
556 rounds to 550 to the nearest tenth. However, if you want the nearest hundredth then it would be 600.
937 rounds to 940
556
556 * 556 = 309,136
I assume that you are referring to 5.56mm in your question?,if so yes you can shoot this ammo in your rifle.The 5.56mm is the metric designation for the .223 Remington cartridge.
Yes there is a difference. They are physically the same size casing, but the 556 military rounds' chamber pressure is ~10,000 psi higher then 223. Military rifles generally have chambers with a different throat configuration than normal sport 223 rifles. This being said, I would not recommend shooting 556 unless your rifle was designed for the higher pressures.
556 = 55,600%
70% of 556 is 389.2. Which means that 166.8 is 30% of 556.
why you asking me 556-thousands = 556/1000 = 0.556 as a decimal
