The Great Lakes Firearms GL10 is a semi-automatic rifle chambered in .270 Winchester, built around a 24-inch stainless steel barrel with a threaded muzzle. It carries a 5-round capacity and mounts an M-LOK rail for attaching accessories, giving hunters a self-loading option in a caliber more often paired with a bolt gun.

The GL10 sits in the budget end of the semi-auto hunting rifle category, and owner opinions reflect that. Reliability out of the box is generally described as adequate, with the action cycling without much fuss once broken in, though fit and finish on some examples draw comments about rough edges compared to pricier semi-autos.

Handling gets mixed feedback. The stainless barrel and threaded muzzle are appreciated for letting owners add a brake or suppressor, and the M-LOK rail makes mounting optics straightforward. Balance and weight in a .270 chambering are noted as manageable for field carry, though a few owners wish the stock and trigger felt more refined.

On value, the GL10 tends to be picked as an affordable alternative to bolt-action hunting rifles in the same caliber. Owners weigh the semi-auto's faster follow-up shots against the tighter accuracy some associate with a bolt gun, and aftermarket support is smaller than for mainstream AR-pattern rifles.
