Lets You Install a Folding Stock On Your Chassis-System Bolt Rifle
The BTFA Buffer Tube Folding Adapter from SB Tactical provides a simple upgrade to improve the portability of your bolt action chassis-system rifle by giving it a folding buttstock. The BTFA lets you put a folding stock on any rifle that uses a standard AR-15 buffer tube as the attachment point for mounting its buttstock. The adapter simply screws into the rear of the chassis - where the AR-15 buffer tube would normally go - and then the buffer tube is screwed into the BTFA.
The BTFA adds only 1.1" to your rifle's length-of-pull when installed. You can either compensate for that by extending the buttstock a little less, if it's an adjustable M4 carbine type stock. And many shooters with longer arms will welcome the additional LOP.
- Reversible for right- or left side-folding - whatever works best for you
- Securely locks in the open AND closed positions
- Accepts are AR-15 buffer tube, A2 rifle or M4 carbine type
- Minimal weight (only 3.4 oz.) & bulk (1.1" added to LOP)
- Caution: Fits chassis system rifles only, NOT standard AR-15 platform (see Gun Tech Note below)
SB Tactical's BTFA Buffer Tube Folding Adapter is constructed of strong yet lightweight 6061 T6 aluminum with a tough military Type III hardcoat anodized finish to resist surface wear and corrosion.
Brownells Gun Tech™ Note: You're probably thinking, "So why can't I use the BTFA to put a folding stock on my standard-configuration AR-15? To ensure maximum strength, the BTFA has solid bulkheads that prevent the passage of a recoil buffer, so it will NOT work with the standard AR-15 operating system. For the AR-15, we offer the Law Tactical Gen3-M folding stock adapter (#100-015-850).
