The Great Lakes GL10 in .270 Win is a semi-automatic rifle with a 24-inch barrel, 5+1 round capacity, and a fixed Hogue overmolded stock. The receiver is machined from 7075-T6 aluminum. A muzzle brake reduces recoil. Barrel twist rate is 1:10". At 13.3 lbs it's on the heavy end, which is the trade-off for a semi-auto platform in this caliber.

Users of the Great Lakes GL10 .270 Win tend to focus on two areas. Accuracy and reliability get the most praise -- the .270 Win caliber is appreciated for its range and stopping power in hunting situations, and the semi-auto action makes follow-up shots quick. Build quality and the black finish are described positively.

Weight is the consistent complaint at 13.3 lbs; some hunters find it tiring to carry over extended terrain. A few users note concerns about magazine feeding reliability with certain ammo types. Recoil is generally considered manageable, but the muzzle brake prompts some debate. The general recommendation from owners is that it's a solid hunting rifle, but worth handling before buying given the weight.
