Works perfectly with the Tyrant magwell

Review by Charles S. on 8 Apr 2025 review stating Works perfectly with the Tyrant magwell
The added weight from the 5 plus rounds and magwell gave me more recoil control.

Not flush with their own adapter

Review by Sam S. on 8 Apr 2025 review stating Not flush with their own adapter
It does the job, little bit heavy, but it is at the shoulder so you can compensate. But for the money you pay for it, why doesn't your brace and your adapter fit correctly.
