1913 Picatinny Interface – Bufferless Receiver Extension – B.R.E. – Black / FDE
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Samson’s B.R.E. Bufferless Receiver Extension is a folding 1913-interface receiver extension built for bufferless platforms that use AR-style adjustable carbine stocks. It gives compatible setups a six-position adjustable extension without needing a traditional AR recoil system hanging off the back.
Available options are organized below under Variants. Verified finishes in this batch are Black and Flat Dark Earth.

What it does
This gives a bufferless firearm an adjustable receiver extension so you can run a compatible mil-spec AR carbine stock on a 1913 rear rail platform. It adds folding capability and keeps the package lean for compact transport and storage.
Why it’s worth it
This is the clean bridge between bufferless rail-end platforms and common AR-style stock fitment. Instead of cobbling together weird rear-end hardware, you get a purpose-built extension that was actually designed for the job.

Install notes
Install on a true 1913 rear rail interface and verify stock compatibility before use. This is designed for bufferless platforms, not for conventional AR systems that require a functioning rear buffer assembly.
Verify before you buy
Verify your firearm is a compatible bufferless platform and that your intended stock is mil-spec AR carbine compatible. This listing does not include the stock itself.
