Description
There's something about a 20-inch rifle with a fixed carry handle that just feels right. The H&R M16A2 recreates the rifle that replaced the A1 in Marine Corps service in 1983, and Harrington & Richardson (now building retro rifles under the Palmetto State Armory umbrella) got the details right. The heavier A2 profile barrel past the gas block, the ribbed round handguards with heat shields, the finger-ledge pistol grip, the brass deflector. If you carried one of these in the service or you're building out a retro collection, the little things matter, and this rifle nails them.
What Makes This M16A2 Clone Worth a Look
The barrel is where this rifle earns its keep. It's a 20-inch chrome-lined A2 profile tube with a 1:7 twist, so it stabilizes everything from 55 grain plinking ammo to heavier 77 grain match loads, and the chrome lining means it will shrug off high round counts and corrosive conditions for years. The muzzle is threaded 1/2×28 and wears the classic A2 flash hider. Underneath, you get forged 7075-T6 receivers, a full-auto profile bolt carrier with a Carpenter 158 bolt, and a rifle-length gas system that gives the smooth, soft-cycling recoil impulse that made the 20-inch AR a joy to shoot in the first place.
Shooting the H&R M16A2
The A2 sights on the carry handle are widely considered some of the best irons ever issued, with dual apertures and easy windage and elevation adjustments right at your fingertips. Pair those with the long sight radius of a 20-inch rifle and you can ring steel way out there without spending a dime on glass. H&R's retro trigger keeps the feel period-correct, and the fixed A2 stock gives you a consistent cheek weld shot after shot.
Whether it's for the retro rack, service rifle practice, or just a dependable range gun that runs on cheap and plentiful 5.56, this one checks the boxes. It ships with a 30-round magazine so you're ready to load up and go.

Frequently Asked Questions
Is the H&R M16A2 barrel really chrome-lined?
Yes, this version features a 20-inch chrome-lined A2 profile barrel with a parkerized exterior finish. Chrome lining adds bore durability, resists corrosion, and makes cleanup easier, which is exactly why the military spec'd it. It's a nice upgrade over some retro clones that skip the lining.
What ammo does the 1:7 twist barrel shoot best?
The 1:7 twist is the true military spec for the A2 and it handles a wide range of bullet weights. It stabilizes heavier 62 to 77 grain loads especially well, and standard 55 grain range ammo shoots just fine too. Since it's chambered in 5.56 NATO, you can safely run both 5.56 and .223 Remington.
Can I remove the carry handle and mount an optic on this M16A2?
No, the carry handle on a true M16A2 upper is fixed, not detachable, and this rifle stays faithful to that design. That said, the A2 aperture sights are regarded as some of the finest irons ever fielded, with adjustable windage and elevation built right in. If you want a flat-top for optics, you'd want an A4 style rifle instead.
Who makes the H&R M16A2 today?
The Harrington & Richardson name dates back to the late 1800s, and the company even produced M1 Garands and early XM16E1 rifles for the military. Today the brand is owned by Palmetto State Armory and serves as their dedicated retro rifle line. These rifles are assembled from US-made parts with proper H&R rollmarks.
