Expect to "shell" out anywhere from $2K to $7K for a gun that offers exceptional accuracy and a quality-built platform. The 16.5-inch barrel for those who like it shorter is stable and the accuracy of the rifle is decent. 223/5.56x45 chamber and detachable magazines for customization is a good option. ![]() If you want a finished rifle ready to plug-n-play, then theĬZ Bren 2 MS Carbine with a. ![]() The second generation by Brown Ells is also Mil-Spec designed to fit on the AR-15 Mil-Spec Lower. If we are talking about modifying the AR-15 platform, why not reach for theīRN-180. You have some incredible options for shooting either the 5.56 round or those guns that take the 9mm round.įor the 5.56 round, you can opt for the AR-15 guns or those that are not AR-15. Which is better steel or brass for casings and lead, alloys, copper, or steel for bullets? 4. Generally, bullets are stainless or lead, but copper is also available as are alloys. Each of the construction material options changes the round slightly and therefore impacts the round's attributes and can change the performance of the round too.įor example, you can buy 5.56 or 9mm brass or steel casings, and then you have options for bullet components. Given that round manufacturers have a limited number of metals from which to make quality rounds, you see that the above data can vary depending on the materials used to create the bullet and round. 5.56x45mm NATOĥ5 grain - Velocity 99.3 meters per second converts to 3,260 feet per second - Energy -1,294 feet-pound (LBF) - 20-inche barrelĦ2 grain - Velocity 948 meters/second converts to 3,110 feet per second, Energy - 1,325 feet-pound (LBF) - 20-inch barrelĦ3 grain - Velocity 856 meters/second converts to 2,81- feet per second, Energy - 1,325 feet-pound (LBF) - 20-inch barrel. Non-NATO 9mm bullets may weigh only 5.2 grams with 80.2 grains and 3.65 grams with 55 grains.ġ15 grain - Federal FMJ - Velocity 360 meters per second converts to 1,180 feet per second - Energy 355 feet-pound (LBF) - 4.65 inches.ġ15 grain - Underwood JHP - Velocity 430 meters per second converts to 1,400 feet per second - Energy 5015 feet-pound (LBF) - 4.65 inches.ġ24 grain -Federal FMJ - Velocity 350 meters per second converts to 1,150 feet per second - Energy 364 feet-pound (LBF) - 4.65 inches.ġ24 grain -Norma ENVY FMJ - Velocity 410 meters per second converts to 1,345 feet per second - Energy 498 feet-pound (LBF) - 4.65 inches. At 128 grains, the NATO 9mm bullet weighs 8.3 grams. 9mm weight - NATO 9mm bullets weigh 7.0 grams at 108 grains.Case length is 19.15 mm (Luger) - overall length is 29.69 mm (Luger.) ![]() 9mm Size - ranges in diameter from 9.02mm to 9.09mm which is caused by the variations in plaiting material.The tapered diameter is 0.253 at the neck and 0.377 inches wide at the base of the bullet. 5.56 Size - Casing - 1.760 inches, total length including casing is 2.260 inches long.That size difference goes back to their purposes -the 5.56 being a rifle round and the 9mm is designed for handguns. SizeĪ quick look at the two rounds will show you that the 5.56 is much larger than the 9mm. It also helps define which is better for a specific situation such as close quarter home defense or competition shooting. Do you need a round with more impact (energy) or one that will get from point A to point B faster? This can become a moving target vs. The heavier 9mm require more energy to push them out of the barrel, but the lighter (fewer grains) of the 5.56 rounds travel faster. The difference in grains between the two rounds is a trade-off in performance. Average 9mm rounds are commonly in the 115 or 124-grain weight while common bullets for the 5.56 rounds keep the grains under 63 with 62 and 55 grains being very common. Since we measure the weight of a round in terms of grains, the 9mm is a heavier round. For the most part, 5.56 is a rifle caliber, and 9mm we talk about in terms of handguns. The 5.56 is a rifle bullet whereas the 9mm round is for pistols though there is some interchangeability in that you have 9mm rifles andĥ.56 pistols. Two Go-to Calibers for AR platforms and Handgun Applicationsīoth bullets are very common. Types of firearms that use these two categories of rounds. We’ll compare the bullet's physical attributes and performance and discuss the This guide looks at the two types of ammo for semiautomatic and fully automatic applications. ![]()
