Rail System- Our sample of the Adams Arms Mid Elite Tactical was equipped with the Samson STAR M-EX-P Tactical Rail System. The STAR-M-EX-P is a free-floating / mid-length rail system that provides rails extending out beyond the piston gas block housing at the 3, 6 and 9 o‘clock positions.

Two unique features of the STAR-M-EX-P are the engagement tabs on either side of the rail system and a lower rail half which separates from the upper rail half via a quick release pin located directly in front of the upper receiver pivot pin lugs.

The engagement tabs on either side of the STAR-M-EX-P interlock with the upper receiver preventing loosening of the barrel nut and subsequent rotation of the rail system.

Pulling the quick release pin located directly in front of the upper receiver pivot pin lugs, frees the lower rail half to slide forward within the upper rail half. This allows for the complete removal of the lower rail half facilitating the installation of an M203 Grenade Launcher. This feature is also beneficial for cleaning of the barrel exterior and rail system interior surfaces after a hard day of use at the range or for that evening routine cleaning session at your next carbine training course.

Machined to Mil-Spec 1913 from 6061-T6 aluminum, the four rails of the system are identified in the typical fashion with engraved T-Markings. Hard coat black anodized, the monolithic rail system has an operating weight of 16.0 ounces and is equipped with rotation limited quick detach sling sockets at the rear of each side rail, as well as the front of the bottom rail.

Upper Receiver- The upper receiver of the Adams Arms Mid Elite Tactical is of the standard flat-top variety with T-Markings and equipped with M4 feed ramps. A standard charging handle is included. A steel bushing pressed into the face of the upper receiver ensures for a smooth travel of the gas system sleeve/drive rod assembly during operation.

Barrel- Chambered in 5.56mm NATO, the Melonited barrel of the Adams Arms Mid Elite Tactical is a 1:7 RH twist with mid-length gas system, finished off with the standard crush washer / A2 flash suppressor arrangement.

Gas System- The Mid Elite Tactical gas block assembly is attached to the barrel with straight pins, and is machined with a 1913 Picatinny rail which mates up to the STAR-M-EX-P’s upper rail, forming a continuous monolithic rail system. The gas system is regulated through rotation of the gas plug situated at the front of the gas block assembly.

The gas plug is equipped with 4 detents at the 9, 12, 1 and 3 o’clock positions. The 9 o’clock position facilitates removal and installation of the gas plug and the sleeve/drive rod assembly, allowing for routine maintenance and cleaning.

Following around in a clock-wise direction, the 12 o’clock position allows for full unregulated gas flow, with the 1 o’clock position being the lower regulated gas flow position, ideal for firing with a sound suppressor attached to the weapon.

The final 3 o’clock position entirely cuts off all gas flow to the piston system.

Bolt Assembly- The one-piece bolt carrier of the Mid Elite Tactical is Melonite coated, and is widened at the rear and equipped with ramps to eliminate the bolt carrier tilt that is associated with some piston operated AR’s.
