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. 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.



Standard or Enhanced options refer to features on the Buffer Tube Cover that comes with your kit and are just like those offered on all models of the FRS-15 Stock. Our FRS-15 kits are not only designed to be the most ergonomic solution for featureless conversions, they are also tailored to meet our customers individual needs and budgets. Many people use their rifles in different ways and our Standard and Enhanced kits allow for maximum utility. The difference in the two kits is the Buffer Tube Cover. The Standard FRS-15 kits are tailored more for those who primarily shoot from a bench or prefer a two point sling. The Enhanced FRS-15 kits include two additional quick detach sling hard points. The advantage is that if a user prefers a single point sling, the center of gravity is in line with the barrel which keeps the muzzle pointed straight down.




The vast majority of .308 receivers are extended by 1/2" in the rear to accommodate a larger upper receiver and bolt carrier group. In order for the FRS-15 GEN III Carbine and Rifle kits to fit properly, an additional A2 spacer and .308 receiver adapter are necessary.  Bundle kits are avalable that include everything you need for attaching a FRS-15 Gen III stock to your DPMS, Black Rain Ordnance, or Windam Weaponry .308.  Click here to go strait to the stock bundles.
