Double Star ACE AR-15 RECEIVER BLOCK A501

The DoubleStar ACE AR-15 Receiver Block allows users of certain AR-15 cycling systems where the bolt-carrier group travel is limited to the length of the receiver, enabling owners to use Ace stocks and accessories with the company's receiver block.

Systems that can be used with the ACE AR-15 Receiver Block include the SIG Sauer 556, AR .22-caliber conversions, OA 93 systems and certain gas-piston systems that limit bolt travel.

• Constructed from 7075-T6 aluminum

Those with an AR-15 looking to add any of ACE's versatile and durable accessories to their rifle can easily add the DoubleStar ACE AR-15 Receiver Block in order to allow for accessory installation.
