***Note: You must be 21+ to purchase a serialized lower. Lower receivers will be shipped to your provided FFL while upper receivers will be shipped to you. Please allow for 2-4 week lead time for parts assembly and QC.  ***

This builder kits consist of a complete upper with a TiN ARC Bolt Carrier Group, C.H.O.D.E Charging Handle, and complete lower. Both components are ready to be assembled by the end user.

After a thorough development cycle, the All-Rounder Carbine is now available for military, law enforcement, and commercial procurement.

Finish disclaimer:

The ARC, like the LP-1, is made for the professional end user. We prioritize function over aesthetics; it is completely normal (and even expected) that your rifle will have small imperfections including forging marks, striations in the anodizing, tooling marks from our various CNC operations, handling marks from the test fire procedure, and varying shades between the aluminum. 

All L&S aluminum components are finished in Type III hard coat anodize because of its surface hardness, abrasion resistance and chemical resistance. Type III adds a 0.003” layer of hard aluminum oxide to the substrate’s surface. This layer is grown via a proprietary, several step electrolytic bath that prioritizes surface protection over all else, and the resultant color is dependent upon the saturation of compounds in the various baths, dye concentration, dye mix ratio, aluminum oxide case depth, starting smoothness of the part, etc. 

Rails, receivers and other aluminum parts can and will vary from one part to the next, even within the same batch. It is nearly impossible to have a perfectly matching ARC, thereby making each rifle unique. The photos above are a representation of what you will receive, but it may not be a 1:1. Even with the inherently inconsistent nature of anodizing, we consciously selected Type III Ano for surface finish longevity–to date, there is no cerakote (or other painted finish) that can beat it.
