Aluminum Side-Folding Stock
Arsenal’s new AK-227 hard anodized aluminum side-folding stock provides better ergonomics and functionality in a lighter and stronger design. It includes four non-rotating QD points on the stock for precise sling attachment. The buttstock body is CNC machined from a single piece of aluminum and hard anodized for strength. The attachment parts are heat treated carbon steel. The stock has a cheek weld groove machined for a better fit. All the parts are machined in house, down to the rivets which are produced in a CNC machine to ensure a flush fit. The attention to detail and manufacturing the parts in house has produced a high quality stock with tight tolerances, that’s built to last.
Shipped in the Eternity Case Universal Fit Premium Gun Case
The Universal Edition uses pre-scored pick-and-pluck foam so you can create a custom fit for any rifle, handgun, optic, or gear. The crush-resistant shell, IP67-rated seal, and pressure valve defend against dust, impact, and full water submersion. Metal-reinforced mil-spec QD points make tactical carry easy through rain, rivers, and rough terrain. For teams and armories, the stackable geometry, per military requirements, lets cases secure for transport by truck or cargo aircraft. A compact footprint, tactical utility, and Limited Lifetime Warranty make it the versatile gun case that goes anywhere.
Arsenal’s Exclusive Milled and Forged Receiver
Each SAM7SF receiver is milled from a hot-die hammer forged receiver blank by the Arsenal Co. of Bulgaria. Arsenal’s hot-die hammer forging produces stronger and finer-grained steel. Internal voids and cooling deformations are eliminated by the 5-ton hammer forging process.
Each forged receiver blank requires over 5.5 hours of milling before assembly. This forging and milling process is complex and time-intensive, but Arsenal’s meticulous attention to detail delivers a receiver of unequalled strength, precision and durability.
