The ATA model SP Over & Under shotgun embodies the synthesis of 50 years of master craftsmanship and contemporary technology. The SP over &; under shotgun is offered with either a standard steel or a lightweight aluminium alloy receiver; both feature a single selective trigger mechanism with automatic ejectors. The alloy action features a steel insert inlet into the standing breech face to resist scuffing and reduce wear. This produces a gun weighing just 6.2 Ibs (2.8 kg) that is both easy to handle and comfortable for hunters to carry. All SP models are enriched with quality Turkish walnut wood for the stocks and forends, making them extremely attractive to the eye as well as being desirable to own at a very competitive price. Barrels are built and finished to a high standard, with a very durable high gloss finish which completes the attractive appearance of these shotguns. The barrels accept interchangeable steel alloy mobile chokes, which allow hunters and shooters to select degree of shot pattern they require for the type of targets they are preparing for, thereby tailoring the gun to meet their specific needs.
