There are a wealth of parts on the market for the small arms community to choose from. While many different manufacturers offer quality parts for the AR-10 platform you may find that not all parts are created equally. If you need a small parts 308 lower kit designed for use with billet receiver sets, the Spikes Tactical Lower Receiver Small Parts Kit is the kit you need.

Created for Billet Receiver Sets

This Spikes Tactical AR10 lower kit was designed and manufactured specifically to work with their own billet receiver sets, the Jack10 and Livewire 308 sets. Using this set along with the buffer tube assembly, stock and trigger group you prefer will complete the lower receiver you’ve based on a high-quality billet receiver set.

Quality Parts For Your Build

The Spikes Small Parts AR10 Lower Kit features a group of components hand chosen for their better-than-Mil-Spec performance. In each LPK small parts kit, you will receive the following parts: parts to complete a safety selector assembly, a Mag catch assembly, a buffer retainer spring and plunger and Spike’s Pro Grip with a ¼ x 28 hex screw and star type lock washer. Spikes leaves nothing to chance when they select the parts that they include in their kits, so you can rest easy knowing that you won’t be let down by an inferior small part that wasn’t designed to take the punishment of larger caliber applications.

American Made Quality

Every item Spike’s Tactical offers, from their 308 lower kit to their receiver sets is made in the United States. Only American made quality will do. You’ll never find an inferior foreign part in a Spike’s kit.
