As you probably know, the original AR-15 platform has changed through the years and these improvements are marked as the different types of AR-15's. The weapon became the M4 in 1991. This accumulating carbon and vaporized metal build-up within the receiver and bolt-carrier negatively affects reliability and necessitates more intensive maintenance on the part of the individual soldier. Original M16 stocks were made from fiberglass-impregnated resin; the newer stocks were engineered from DuPont Zytel glass-filled thermoset polymers. The complete Spikes forged AR-15 lower receiver comes with Standard Spikes Lower Parts Kit (LPK) and fire control group factory installed. $69.00. As a result, the design was split into two variants: the Air Force's M16 without the forward assist, and the XM16E1 with the forward assist for the other service branches. Also common are higher magnification optics ranging from the 6× power Trijicon ACOG to the Leupold Mark 4 Tactical rifle scopes.

When asked what weapon they preferred to carry in combat, 85 percent indicated that they wanted either the M16 or its [smaller]carbine-length version, the XM177E2." The resulting report found that Army Materiel Command had rigged the previous tests, selecting tests that would favor the M14 and choosing match grade M14s to compete against AR-15s out of the box. Before answering this question, you should note that the AR-15 comes in two variants: Commercial and Mil-Spec. [73] In a 2002 assessment the USMC found that the M4 malfunctioned three times more often than the M16A4 (the M4 failed 186 times for 69,000 rounds fired, while the M16A4 failed 61 times). products sale.Shop for Best Price M16 Lower Receiver Specs And Complete Lower Receiver Parts Kit Ar 15 .

[129][131] The majority of failures were the result of hitting the target in non-vital areas such as extremities. As a result, it became the target of a Congressional investigation. [93] The new buttstock became ten times stronger than the original due to advances in polymer technology since the early 1960s. The KAC suppressor can be fully submerged and water will drain out in less than eight seconds. The Air Force continued to operate these weapons until around 2001, at which time the Air Force converted all of its M16s to the M16A2 configuration. The Air Force, Colt and Eugene Stoner believed that the addition of a forward assist was an unjustified expense. [151] It was developed in 1984, and is one of the earliest privately designed muzzle devices.
