The McMillan Tac-50 is a manually operated, rotary bolt action rifle. The large bolt has dual front locking lugs, and its body has spiral flutes to reduce weight. The heavy match-grade barrel, made by Lilja barrels, is also fluted to dissipate heat quickly and reduce overall weight and fitted with an effective muzzle brake to reduce recoil. The rifle is fed from detachable box magazines, holding 5 rounds each. The stock is made from fiberglass by McMillan Stocks, and is designed to be used from a bipod only. The buttstock is adjustable for length of pull with rubber spacers, and can be removed for compact storage. The rifle has no open sights and can be used with a variety of telescopic or night sights.
In Canadian service, the standard telescopic sight was the McMillan endorsed Leupold Mark 4-16x40mm LR/T M1 Riflescope optical sight that has now been replaced by the Schmidt & Bender 5-25x56 PMII telescopic sight[citation needed]. McMillan also endorses the Nightforce NXS 8–32x56 Mil-dot telescopic sight for the Tac-50.
