#m16a2

Memorial Day Weekend range session! This range session featured only American rifles (or close copies) and service pistols that were used by American servicemen in the line of duty. From left to right, and in chronological order of service, the M1903, the P17, the M1 Garand, the M1 Carbine, the M16A2, and the M4 Carbine. It was a windy day so it was hard to gauge accuracy but the Garand turned in the best group of the day followed by the M4 (optics helped no doubt). I also shot 3 service pistols - an M1917 revolver in 45acp (using moon clips), a 1911 I built from a kit, and a Beretta M9. A tremendously fun day but also a day that gave me a feel for what it might have been like for American soldiers to shoot these guns in training

In the mid-1950s, the U.S. Department of Defense sought a new assault rifle for its infantry, influenced by the adoption of the AK-47 and the U.S. withdrawal from the FAL program. The Springfield Armory's M14, a derivative of the M1 Garand chambered in 7.62×51mm NATO, was adopted in 1958 but soon proved inadequate in Vietnam.

Around the same time, Eugene Stoner developed the AR-10, a 7.62×51mm rifle, but its design struggled with the cartridge's recoil. When the U.S. military switched to 5.56×45mm, Stoner adapted the AR-10 into the AR-15, which ArmaLite proposed to the Army in 1959 but was initially rejected. In 1960, the Air Force, led by Gen. Curtis LeMay, ordered 6,000 AR-15s. By 1965, after proving reliable in combat, the Army adopted it as the M16, with the M16A1 in service until 1984. Before That.. Some Screenshoot I Made Thank you For @chloegamesbroficial For Inspiration! Nice Work Sis!

✨ORIGINAL M16 FAMILY

COLT XM16E1

The Progenitor Of M16 Rifle Series. The one who started it all. The XM16E1 was the first true military-issued M16 variant and played a key role in transitioning the U.S. Army from the M14 Battle Rifle to a lightweight, high-rate-of-fire assault rifle. Despite its early flaws, the refinements made in the M16A1 helped solidify the M16 family as a standard U.S. service rifle for decades. (Thank you for @honeyssims4 For Adorable Pose!)

Key Features of the XM16E1:

Forward Assist: Unlike the initial AR-15 and early M16 models, the XM16E1 introduced a forward assist on the right side of the receiver to manually ensure the bolt was fully locked. This was a response to reliability concerns, though Stoner himself opposed its necessity.

Three-Prong Flash Hider: It retained the three-prong flash suppressor, which was later replaced with a birdcage-style suppressor on the M16A1 due to durability issues (the prongs could snag on vegetation).

Chrome-Lined Chamber Issue: Early XM16E1 rifles lacked chrome-lined chambers, leading to frequent malfunctions when used in Vietnam's humid jungle conditions. Fouling and corrosion contributed to "failure to extract" malfunctions, which were later addressed in the M16A1 by adding a chrome-lined chamber and barrel.

Full Auto & Semi-Auto Selector: The rifle featured a selector switch for semi-automatic and fully automatic firing modes.

Early Vietnam Deployment: The XM16E1 was issued to U.S. troops in Vietnam around 1965 and was the first Army-standardized version of the M16 before being officially designated the M16A1 in 1967.

Problems & Fixes:

Ammunition Issue: The original 5.56×45mm M193 rounds used ball powder instead of extruded powder (as originally intended), leading to excessive fouling and jamming.

Cleaning Kits & Training: Many soldiers were not initially issued cleaning kits or proper maintenance instructions, worsening the reliability issues.

M16A1 Upgrade: The XM16E1 was formally redesignated as the M16A1 in 1967, incorporating a chrome-lined chamber and barrel, improved buffer system, and closed-end flash suppressor to resolve its issues.

COLT M16A1

The M16A1 was the first fully standardized M16 variant adopted by the U.S. military in 1967, replacing the XM16E1 and improving upon its shortcomings. It became the primary service rifle for U.S. forces during the Vietnam War and remained in widespread use until the 1980s. (Thank you For @plazasims For "Cliff Unger" Uniform!)

Key Features & Improvements Over XM16E1:

Chrome-Lined Chamber & Barrel – Addressed the fouling and corrosion issues that plagued the XM16E1 in Vietnam's humid environment.

Birdcage Flash Hider – Replaced the three-prong flash suppressor, which was prone to bending and snagging on vegetation.

Forward Assist – Retained from the XM16E1, allowing soldiers to manually close the bolt if needed.

Reinforced Buttstock & Pistol Grip – Made from stronger polymer to prevent cracking.

New Buffer System – Helped reduce felt recoil and improve reliability in automatic fire.

30-Round Magazine Compatibility – Originally issued with 20-round magazines, but later compatible with the more practical 30-round STANAG magazines.

Weight & Length – Weighed around 3.9 kg (8.6 lbs) loaded and measured 986 mm (39 inches) in length, making it much lighter than the M14 it replaced.

Combat Use:

Vietnam War (1967–1975) – Saw extensive use, replacing the heavier M14. Soldiers appreciated its lighter weight and high fire rate, though early reliability issues due to poor maintenance training and improper ammunition caused setbacks.

Post-Vietnam Conflicts – Used in Operation Just Cause (Panama, 1989) and by allied forces worldwide into the 1990s.

Foreign Military Use – Many U.S. allies adopted surplus M16A1s, with some still in limited use today.

Replacement & Legacy:

By the mid-1980s, the M16A2 replaced the M16A1, introducing a heavier barrel, burst-fire mode, and improved sights. However, the M16A1 remains one of the most widely produced and battle-proven rifles in U.S. history, influencing modern designs like the M4A1 and civilian AR-15 variants.

COLT M16A2/M16A3

The M16A2 is an upgraded version of the M16A1, featuring a longer stock, improved pistol grip, reinforced carry handle, and a more durable round handguard. It introduced a three-round burst mode instead of full-auto M16A3, Variant that Issued for United States Navy Having A Full Auto Configuration like Old M16A1. The rifle also had a heavier barrel for increased durability and accuracy.

The M16A2 saw combat in Operation Just Cause (Panama), the Gulf War, and the Bosnian War. It later served as a reserve rifle in Afghanistan and Iraq and remains a popular service weapon for military and police forces worldwide.

M16A2 (1983 – Standard Issue Upgrade)

Key Features & Improvements Over M16A1:

Stronger Barrel – Heavier profile for improved accuracy and heat resistance.

3-Round Burst Mode – Replaced full-auto with safe-semi-burst to conserve ammo.

New Rear Sight – Adjustable for windage and elevation, improving long-range accuracy.

Longer Stock & Reinforced Grip – More ergonomic design for stability.

Round Handguards – More durable and symmetrical, easier to grip.

Flash Hider Change – Birdcage closed at the bottom to prevent dust kick-up.

Improved Ammunition – Designed for the 5.56×45mm M855 "Green Tip" round, offering better penetration.

Combat History:

First issued in 1983 and widely used in Operation Just Cause (Panama, 1989) and Desert Storm (1991).

Phased out in the 2000s as the M16A4 and M4 Carbine became standard.

M16A3 (1990s – Full-Auto Navy Variant)

How It Differs from the M16A2:

Retains Full-Auto – Uses safe-semi-full auto, unlike the M16A2’s 3-round burst.

Used by U.S. Navy and SEALs – Needed for maritime operations and boarding teams.

Physically Similar to the M16A2 – No other major differences besides the fire control group.

Limited Use & Replacement:

Never widely adopted outside of Navy units and special forces.

Eventually replaced by the M16A4 and M4A1 due to modularity and compact size needs.

COLT M16A4

The M16A4 is the final standard-issue variant of the M16 rifle family, introduced in the late 1990s to replace the M16A2. It was widely used by the U.S. Marine Corps and some Army units, particularly during the Iraq and Afghanistan wars. The M16A4 was the last major evolution of the M16 series, transitioning the rifle into a more modular, optics-friendly platform.

Key Features & Improvements Over M16A2:

Flat-Top Receiver with Picatinny Rail – Allowed for easy mounting of optics, scopes, and accessories, unlike the fixed carry handle of the M16A2.

Removable Carry Handle – Featured adjustable iron sights but could be detached for mounting optics like the ACOG (widely used by U.S. Marines).

Three-Round Burst Mode – Retained the safe-semi-burst firing modes from the M16A2 (no full-auto, unlike the M16A3).

Knight’s Armament M5 RAS (Rail Adapter System) – Allowed attachment of foregrips, lasers, flashlights, and grenade launchers (M203/M320).

Heavy Barrel – Improved accuracy and heat resistance for sustained fire.

30-Round STANAG Magazine – Standardized across NATO forces.

Combat Use & Replacement:

Widely used in the Iraq War (2003–2011) and Afghanistan War (2001–2021) by U.S. Marines.

Phased out in favor of the M4A1 carbine, which offered greater mobility in urban warfare.

Still in use by Marine reserves and allied forces worldwide.

🎈CARBINE FAMILY

The AR-15 carbine family includes a wide range of compact, lightweight rifles derived from the original AR-15/M16 platform. Carbines typically have shorter barrels (14.5 inches or less) and are designed for mobility, versatility, and close-quarters combat (CQC).they has evolved into one of the most widely used and modular weapon platforms worldwide, serving military, law enforcement, and civilian shooters.

COLT CAR-15 (XM177E2 Model)

The First Of The Family The Colt CAR-15 was a family of compact, lightweight rifles and carbines developed in the 1960s as shortened versions of the M16/AR-15 platform. The name CAR-15 ("Colt Automatic Rifle-15") was originally an umbrella term for Colt’s modular rifle system, but it later became associated specifically with short-barreled carbines.

SPECIALIZED VARIANTS

This Part Will covered the Unconventional Layout Of AR-15 Rifle something that Slightly Deviated with Their Original Mainstream M16 Or M4 Guidelines.

Colt 9mm SMG (Colt RO635)

The Colt 9mm SMG, also known as the Colt Model 635, is a submachine gun (SMG) chambered in 9×19mm Parabellum, designed as a pistol-caliber variant of the M16/AR-15 platform. It was developed in the 1980s for law enforcement, special forces, and security personnel who needed a compact, controllable firearm for close-quarters combat (CQC).

Key Features of the Colt 9mm SMG (Model 635)

1. 9mm Blowback Operation (No Gas System)

Unlike the M4/M16’s gas-operated system, the Colt 9mm SMG uses a simple blowback mechanism.

Lacks a gas tube, gas block, or forward assist, making it simpler and more reliable with 9mm ammo.

2. Shorter 10.5-Inch Barrel

More compact than the M16 (20 inches) or M4 (14.5 inches).

Perfect for CQB, SWAT, and VIP protection.

Often fitted with a threaded barrel for suppressors.

Standard M16A1-style upper receiver, with integrated iron sights and no Picatinny rail (early versions).

Some later versions feature flat-top Picatinny rails for optics.

5. Fire Selector: Safe-Semi-Full Auto (Model 635)

Model 635 (Standard SMG): Full-auto (Safe/Semi/Auto)

Later law enforcement models (RO995, RO699, etc.) have semi-auto configurations.

Combat Use & Operators

Though not widely adopted by the military, the Colt 9mm SMG became popular among:

FBI SWAT & HRT (Hostage Rescue Team)

DEA, ATF, and Secret Service

U.S. Navy SEALs (limited use in the 1980s–1990s before transitioning to MP5s & HK416s)

Foreign law enforcement agencies (e.g., Colombia, Mexico, Middle Eastern special units)

Colt CM901 (Colt Modular Carbine 901)

The Colt CM901 (Colt Modular Carbine 901) is a multi-caliber, modular battle rifle, designed to bridge the gap between 5.56×45mm NATO (M4/M16) and 7.62×51mm NATO (.308 Winchester) rifles. Developed by Colt Defense, it was unveiled in 2010 as a highly adaptable AR-platform weapon for special forces, designated marksmen, and infantry roles.

Key Features of the Colt CM901

1. Multi-Caliber Compatibility (7.62 NATO & 5.56 NATO)

Primary caliber: 7.62×51mm NATO (battle rifle performance, extended range).

Can quickly convert to 5.56×45mm NATO by swapping the upper receiver and using a magazine adapter.

Compatible with standard AR-15/M4 uppers, making it one of the most versatile battle rifles on the market.

2. Monolithic Upper Receiver

The CM901 features a one-piece, free-floating monolithic upper receiver, improving:

Accuracy (more rigid than two-piece designs).

Optic mounting (full-length Picatinny rail).

Accessory attachment (foregrips, lasers, bipods).

Provides a seamless rail system similar to the LMT MWS and KAC SR-25.

3. Shorter 16-Inch Barrel (Battle Rifle in a Carbine Package)

Compact for a 7.62 NATO rifle, giving it more maneuverability than traditional battle rifles like the M14 or SCAR-H.

Available in various barrel lengths (13”, 16”, and 20”) for different mission needs.

4. Ambidextrous Controls

Features ambidextrous safety selector, magazine release, and bolt catch, making it ideal for left-handed shooters.

A big improvement over standard AR-10 platforms, which typically lack full ambidextrous controls.

5. Battle-Proven Reliability

Uses a reinforced lower receiver to handle the power of 7.62 NATO rounds, while still functioning smoothly with 5.56 NATO conversions.

Built to military durability standards, making it rugged and reliable for combat use.

Why the CM901 Didn't Fully Replace the M4/M16

Heavier than standard M4 carbines (even with a 5.56 upper).

7.62 NATO recoil & ammo weight limit its role in CQB settings.

SCAR-H and HK417 were preferred for SOF battle rifle roles.
