Any AR-15/AR-10 cartridge cases that are derived from the 7.62x51 can also be formed from these listed calibers. (7.62x51 & .308 are similar in external dimensions though the Brass has different internal capacity and Max PSI recommendations are different & Chambers are different.) AR-10 :The AR-10 is slightly larger and heavier than the AR-15 ...
This type of buffer cushions the battering force of repeated metal on metal impact, reducing wear on parts and lengthening the service life of the firearm. [4] Reduction of perceived recoil discomfort is an immediate added benefit of this type of recoil buffer. [4] Some pneumatic recoil buffers used in firearms are fast, low-power gas springs ...
The current ArmaLite AR-10 is offered in several versions including an A2 and A4 rifle or carbine with a collapsible stock, a target model (AR-10T), a "retro" AR-10B with Sudanese AR-10-style handguard and cocking lever (limited production) and one version chambered in 300 Remington SAUM.
The ArmaLite AR-15 internal piston action was derived from the original ArmaLite AR-10 action and was later used in the M16 rifle action. This internal piston action system designed by Eugene Stoner is commonly called a direct impingement system, but it does not utilize a conventional direct impingement system.

The AR-15's most distinctive ergonomic feature is the carrying handle and rear sight assembly on top of the receiver. This is a by-product of the original ArmaLite design, where the carry handle served to protect the charging handle. [14] As the line of sight is 2.5 in (63.5 mm) over the bore, the AR-15 has an inherent parallax problem. At ...
The Canadian company Colt Canada (formerly Diemaco) licensed production of a rifle (Colt Model 715) and carbine (Colt Model 725), but later went on to produce an entire line of AR-15/M16 pattern weapons developed independently. In May 2005, Colt's Manufacturing Company acquired Diemaco, and the name was changed to Colt Canada.
Carrier tilt is a wear issue that can arise in some gas piston-based firearm operating systems. High pressure gas pushes the gas piston back hitting the bolt carrier.This force pushes the bolt carrier down into the buffer tube wall.
