Extar USA Releases Adjustable Receiver Extension Option

Firearm innovator Extar USA continues to strive in American-made ways to keep shooting affordable and enjoyable. Since the release of the EP9 large-format pistol, consumers have asked for a receiver extension option when converting their large-format pistol to a short-barrel rifle (SBR).

The EP9’s unique design and proprietary features meant that while it shares the look and familiar controls of the AR-15, users didn’t yet have a way to mount one of the many great adjustable stocks already on the market for the AR-15. Further complicating the desire for an adjustable, AR-15-carbine-style receiver extension has been the BATFE threat of reclassifying certain safety devices such as stabilizing braces as only for those who are willing to pay a tax for their safety.

Now there is an option.

The EP Adjustable Receiver Extension is available for those who wish to convert their EP9 Pistol into a registered short-barreled rifle with an adjustable rifle stock. This direct replacement part gives you the ability to mount a wide range of stocks that are designed to fit on AR-15 Mil-Spec diameter receiver extensions.

Quickly and easily install this receiver extension with all tools necessary included! As a factory replacement part, this receiver extension comes with our recoil damper system already installed, so that you do not have to sacrifice the performance or safety of your firearm.


  • Six adjustment points to help you find the right LOP for you.
  • Fits most Mil-Spec diameter AR-15 adjustable stocks.
  • Is compatible with SB-Tactical adjustable braces for AR-15 Mil-Spec sized receiver extensions(such braces may be subject to the NFA).
  • Extar’s recoil damping system pre-installed.
  • Installation tool included.
  • Price: $49.95

As with all Extar USA products, pricing is kept to a minimum by selling direct to consumer. The Adjustable Receiver Extension is available at
