2A-Armament has set out to deliver a factory built, lightweight rifle that combines all of our most popular products into one high quality rifle. We start the foundation of our rifle with the popular BALIOS-lite receiver set. We then add in every titanium component we make, and combine it with some of the best parts found throughout the industry to deliver a turn-key solution at a fair price. Key features include: our BL-RAIL that uses our tension lock design for attachment, M-LOK, or KeyMod mounting solution, 6AL-4V titanium barrel nut, titanium gas block, titanium takedown pins, and titanium T3 Compensator. These items add visual appeal as well as corrosion resistance. Each rifle is hand assembled when ordered, test fired, and backed by our great support staff.

The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
The 5.56X45mm NATO cartridge was designed by James Sullivan, a member of Eugene Stoner's engineering team that developed both the M16 rifle and its original cartridge. The 5.56X45mm NATO was adopted by the U.S. military in 1964 and by NATO in 1980. With bullet diameter of .224-inch, the original M193 military cartridge used a 55-grain bullet at 3250 fps; the current M855A1 cartridge, developed by FN, uses a 62.5-grain bullet at 3020 fps, offering greater range and better penetration. The civilian version of the 5.56X45mm is 223 Remington; the cartridges are dimensionally identical but military chamber dimensions and specifications for military brass are different. It is considered safe to use 223 Remington ammo in a 5.56X45MM NATO chamber, but not a good idea to use 5.56X45mm ammo in a rifle specifically chambered for the 223 Remington. Although the stopping power of .22-caliber bullets remains controversial the 5.56X45mm has served well in now multiple generations of M16 rifles.
