There's something satisfying about a .308 AR that doesn't try to be fancy. The Rock River Arms Mid A4 is built on the company's LAR-8 platform, and it sticks to what works: a 16 inch chrome moly heavy barrel with a 1:10 twist, an A2 flash hider on 5/8-24 threads, and a mid-length gas system that takes some of the sharpness out of the .308 recoil impulse. At 16 inches, the barrel keeps the rifle handy enough to move through timber or work off a bench without giving up the reach that makes 7.62 NATO worth shooting in the first place.
The trigger is the big one. Rock River ships this rifle with their two-stage trigger, and it's a genuine step up from the gritty mil-spec units you find on a lot of factory big-bore ARs. Up top, the forged A4 upper has a forward assist, ejection port door, and a full-length Picatinny rail for optics, with a receiver-height sight rail on the gas block if you want to run backup irons. RRA guarantees 1.5 MOA at 100 yards from this setup, which is respectable performance for a duty-grade .308 out of the box. A Hogue rubber pistol grip and the RRA 6-position Tactical CAR stock round out the furniture, so it fits a wide range of builds and body types without swapping parts.
One detail worth knowing before you buy: the LAR-8 runs on FN FAL pattern magazines rather than SR-25 mags. Metric FAL mags are plentiful and typically cheap, so keeping a range bag stocked won't hurt much. The rifle ships with one 20-round magazine, weighs in at 8.1 pounds, and stretches 38 inches overall with the stock extended. Whether you're after a hog rifle, a ranch gun with real authority, or a .308 to anchor the safe, this one earns its spot the old-fashioned way, by running well and hitting where you point it.
The LAR-8 platform feeds from FN FAL pattern magazines rather than the SR-25/PMAG style used by most other .308 ARs. Metric FAL mags are widely available and generally inexpensive, so stocking up is easy. The rifle comes with one 20-round magazine in the box.
Rock River Arms guarantees 1.5 MOA at 100 yards with this rifle. The 16 inch chrome moly heavy barrel with a 1:10 twist stabilizes common .308 bullet weights well, and the factory two-stage trigger makes it easier to shoot up to that potential.
No iron sights are included. The forged A4 upper has a full-length Picatinny rail for mounting optics, and the gas block features a receiver-height sight rail, so you can add a front sight or set of backup irons that co-witness with a red dot.
A mid-length gas system on a 16 inch .308 barrel meters gas over a longer dwell period than a carbine setup, which softens the recoil impulse and is easier on internal parts. The practical result is smoother cycling and quicker follow-up shots with full-power 7.62 NATO loads.
