Thordsen Customs Keyed Buffer Tube Hard Mount Kit


Thordsen Customs has just announced their new Keyed Buffer Tube Hard Mount Kit that raises the evolution of the AR/AK Pistol Cheek Rests to the next level by providing a stronger connection to the pistol, sleeker lines and 1.5 ounces of weight added to the rear of the pistol for increased balance in the absence of a traditional stock.


The Keyed Buffer Tube Hard Mount Kit utilizes a steel bracket, anti-rotation bridge and steel fasteners to connect a CAA or MFT saddle directly to the Throdsen Customs Keyed Buffer Tube, which coincidentally is the only Buffer Tube this will work with.

Thordsen Customs Releases Picatinny Buffer Tube Assembly


Thordsen Customs has just released their new Picatinny Buffer Tube Adapter which will allow for the attachment of a standard AR-style buffer tube to any AR-Pistol, such as a Sig MPX, Sig P556XI, Rock River PDS, or any other pistol with a rear vertical picatinny rail.



This attachment will give the shooter the ability to add a cheek rest or a stock to convert the pistol into a SBR (federal restrictions and tax-stamp laws apply).



The Picatinny Buffer Tube Adapter is attached using STANAG protocol.  Here is how Thordsen Customs describes STANAG:

The mounting method follows true STANAG protocol using the two back angles and the top of the rail as the contact points. The result is perfect alignment with the centerline of the firearm. A feature that is not attainable with typical side clamping adapters. Another bonus is that there are no visible fasteners or holes on the top and sides of the adapter for a clean sleek look.


The Picatinny Buffer Tube Adapter is made from 6061 T6 Aluminum with 304 Stainless Steel hardware and is compatible with multiple platforms, will fit any picatinny rail using a true STANAG mount and will include a set screw for carbine buffer tubes.

The Adapter is finished with Type III Hard Anodize finish and weighs in at 2.5 oz.
