Introducing the Windham Weaponry R20 Varmint, a masterclass in precision shooting and varmint hunting. This semi-automatic rifle, chambered in 5.56 NATO, also accepts .223 Rem, making it a versatile addition to any firearm collection. The R20 Varmint is designed with a 20" 416 R stainless steel barrel, fluted to reduce weight and increase surface area for cooling, while maintaining the rigidity required for long-range shooting. The barrel is rifled with a 1:8 RH twist, making it well-suited to a wide variety of bullet weights. The muzzle is threaded and comes with a thread protector. The Compass Lake Specification chamber, with an optimized lead angle of 1.5 degrees per side for high ballistic coefficient bullets, is matched with a Carpenter 158 steel bolt for exceptional accuracy. The rifle features a lightweight, thin profile, 15" Windham Weaponry free-float handguard, with a full-length Picatinny rail at the 12 o'clock position, and M-LOK slots. This provides plenty of room for the addition of a bipod, lights, lasers, and other accessories to customize the rifle to your needs. The hardcoat black anodized upper and lower receivers are forged from 7075-T 6 aluminum. The Varmint is fitted with a LUTH MBA-1 adjustable rifle stock, offering an adjustable length of pull and adjustable cheek riser for a comfortable shooting platform from any position. Multiple sling attachment points are integrated into the stock as well. The Windham Weaponry Varmint 5.56 Rifle is a dedicated varmint rifle for the dedicated varmint hunter.
