The PA-10 Gen 3 is a .308 Win AR-10 pattern rifle built on matte black 7075-T6 aluminum receivers and marked G3-10 on the lower. It uses a direct-impingement, semi-automatic action with a manual safety and accepts SR-25/LR-308 pattern magazines.
Its 20-inch stainless barrel features a 1:10 twist and a threaded muzzle fitted with an A2-style birdcage flash hider and crush washer. The bore condition is excellent with sharp rifling, supporting precise performance with .308 Win loads.

The stated capacity is 20+1, and the receivers, handguard, and furniture are finished in matte black, paired with a natural stainless barrel; the A2 flash hider is black.
