Custom rifle builds are a gun guy’s dream. You get exactly what you want, the way you want it. On the other hand, they can be a nightmare, you’re responsible for the selection of everything from the butt stock to the muzzle brake and every little spring and pin in between. To take some of the pressure off you can use parts kits that include a number of small parts so that you can spend more time doing the actual build than the parts order. If you’re building your dream weapon and you need a quality AR-10 Lower Parts Kit for a forged receiver, Spike’s Tactical offers their .308 Lower Parts kit.

Worry Free Performance

Every part in Spikes Tactical AR-10 Lower Parts Kit is handpicked for quality and long term reliability. All of the Springs and detents are better than Mil-spec and the kit features a rounded hammer that won’t give grief regardless of what caliber you use it with.
