Bayco
The Bayco Nightstick TWM-852XL is a compact, rifle-mounted tactical light built for hunters, precision shooters, and operators who need reliable illumination on their long guns. This Picatinny rail-mounted light delivers 850 lumens with a 245-meter beam distance, enough output to light up target areas and identify threats in low-light conditions without overwhelming your night vision or breaking your cheek weld. At just 3.5 inches long and 4.5 ounces, it won't throw off your gun's balance or add bulk to your setup.
Built from aircraft-grade 6061-T6 aluminum with Type III hard anodizing, the TWM-852XL is engineered for durability in the field. The housing carries an IP-X7 waterproof rating, so rain, creek crossings, or heavy condensation won't kill your light when you need it most. The single rear-mounted switch gives you both momentary and constant-on operation—tap it for a quick look, hold it for sustained illumination. Runtime on a pair of CR123 lithium batteries is 1.75 hours at full output, and the light can handle a 2-meter drop without failure.
Installation is straightforward: the light ships with cross-rail inserts pre-installed, two fresh CR123 batteries, and an Allen wrench so you're ready to mount and shoot. This is a no-nonsense tool for hunters working dark timber or late-season sits, tactical shooters running night drills, or anyone who wants white-light capability without complexity.
