Our blemished FRS-15 Stock Kits are assembled using parts that are structurally sound but were rejected by quality control for a variety of cosmetic flaws including dings, dents, scratches, discoloration, rust, and inserts that are missing or crooked.

This batch of blem stocks has a slightly lighter shade of black and shows more glassing than our usual FRS-15. Foam Buffer Tube Covers included in these kits are not blemished and may appear blacker than the stock body. All blemished items are sold "AS IS". All sales are final with no returns, refunds or exchanges. See out terms & conditions. Blems are not available to Dealers.

They're great for a thrasher rifle, custom paint jobs, or hydro dipping!! Supplies are limited so get them while they last!!


Legislation towards the AR-15 and other weapon platforms, in states like California and New York, have made “going featureless” a viable alternative to forced registration. Just like with our earlier models, the FRS-15 GEN III is designed to help law abiding citizens keep their firearms in compliance with current and upcoming laws. Additionally, the more traditional rifle stock look and feel of the FRS-15 GEN III appeals to gun owners nationwide and not just in restrictive states.

Overwhelming demand by our customers was the driving force behind our Rifle Length Recoil kit. Many AR-15 owners utilize a fixed (A2) stock on their rilfes. Changing the recoil system to work with the GEN II FRS-15 stock can get expensive and may alter the rifles cyclic timing making it unreliable or even dangerous. This kit solves that issue by utilizing special shortened spacers that allow the stock to run under the buffer tube. The buffer tube is finished off with a slip on foam cover.


The vast majority of .308 receivers are extended by 1/2" in the rear to accomodate a larger upper receiver and bolt carrier group. In order for the FRS-15 GEN III Carbine and Rifle kits to fit properly and allow sufficient space for the shooters hand to hold the rifle, an additional A2 spacer and adapter are necessary. Please use the links below to select the appropriate .308 adapter and spacer kit.
