Blue Line JRC Spark Takedown Features The Blue Line Solutions JRC Spark Takedown pairs a 17 inch threaded barrel with a 5 inch takedown tube letting the pistol separate into a compact package for low-profile transport and quick reassembly in the field. The AR-15 pattern receiver is finished in anodized black for corrosion resistance and a durable exterior while the Picatinny rail on top provides a mounting surface for optics. Chambered in .45 ACP the pistol feeds from a 13-round Glock-compatible magazine giving the shooter a familiar magazine source and a healthy capacity for a compact platform. A compact buffer tube with a pistol brace completes the shooting platform giving added stability without a shoulder stock. Synthetic furniture keeps the overall package light while standing up to field use and the whole system is built around the included custom sling pack designed specifically to carry the broken-down pistol and its components. The pack lets the shooter move the Spark Takedown discreetly from vehicle to trailhead or truck to stand without drawing attention. One magazine ships with the pistol keeping the kit complete and ready to load out of the pack. For shooters who want a .45 ACP AR-platform pistol that breaks down small and reassembles fast the JRC Spark Takedown bundle is available at GrabAGun.
