HK SL8 Magazine - 10 Round - Factory - SKU: 217830S - UPC: 642230248885

Product Description

The HK SL8 10-Round Factory Magazine is an authentic German-manufactured OEM replacement magazine designed specifically for the Heckler & Koch SL8 sporting rifle series. Built directly by HK in Oberndorf, Germany, this single-stack 10-round magazine is precision-engineered to meet strict factory tolerances, ensuring flawless feeding, smooth chambering, and 100% operational reliability for .223 Remington / 5.56x45mm NATO rifles.

Constructed from high-strength, steel-reinforced translucent translucent/black polymer, the magazine body provides superior impact resistance and structural rigidity against temperature extremes and field use. The single-stack feeding design is tailored precisely to the HK SL8 magazine well receiver, presenting cartridges at the optimal angle to avoid nose-dives and bolt face misfeeds.

Featuring a high-tensile stainless steel wire spring and an anti-tilt polymer follower, this genuine HK factory magazine delivers consistent upward feeding tension across all 10 rounds, complete with reliable last-round bolt hold-open performance.

*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits factory HK SL8-1 and SL8-6 single-stack rifle magwells chambered in .223 Rem / 5.56mm. (Will NOT fit standard double-stack AR-15 magwells or converted G36 magwell adapters without modification).

1. Verify host HK SL8 rifle is completely clear, magazine removed, and chamber visually and physically confirmed empty.
2. Load .223 Rem / 5.56mm cartridges into the single-stack magazine body, ensuring each case rim seats flush against the rear spine wall.
3. Insert the magazine straight into the SL8 lower receiver magwell until the paddle magazine release locks firmly into place.
4. Cycle the action to chamber a round, or lock the bolt back on an empty magazine to confirm last-round catch engagement.
5. To clean internal components, depress the floorplate locking pin and slide the baseplate forward to remove the spring and follower. Wipe internal housing dry with a clean cloth.
