Jay, member, from MO, United States, asked on December 26, 2025

Will this be suitable for an AR-10 .308? Additionally, does it include all the required hardware for installation?

Manufacturer Answer
A
Answered by Phase 5 WSI, Manufacturer from CA, United States, on December 31, 2025

The EBRv2-308 works on DPMS pattern .308 rifles. If you would like to verify fitment for a specific platform, please email Phase 5 directly. This product does not include any additional hardware or accessories. The roll pin screw and the bolt catch spring / plunger will either be existing on the rifle, in your Lower Parts Kit, or need to be purchased separately.

Will it work for Sig 716i?

Manufacturer Answer
A
Answered by Phase 5 WSI, Manufacturer from CA, United States, on July 09, 2025

Our Extended Bolt Releases do not work on the SIG716 rifles. That rifle uses a specific bolt catch that is not interchangeable with the EBR.

Is this lever compatible with ABC AR-10 Lower

Manufacturer Answer
A
Answered by Phase 5 WSI, Manufacturer from CA, United States, on April 23, 2025

Yes. It appears that ABC Rifle CO uses Aero M5 lowers for their builds, so this will be compatible with the Aero M5.
