General advisements:

*AR grips with extra tang may not fit.

*When attaching accessories to the handguard M-lok slots, avoid using screws with Loctite, as it can easily strip the polymer slots. Use screws without Loctite for best results.

*Handguard with 16" barrel my inhibit use of certain suppressor mounts.

Realization of a Dream

Sebastian on 10th Mar 2025

It's the closest thing to the UK's... controversial... service rifle the American consumer has ever been offered, with the benefit of being better in every way than what either Enfield or H&K could cobble together for the original - fit, finish, and functionality are excellent. Whether you've lusted after the unobtanium that is the L85 because of Battlefield, CoD, or seeing British troops on CNN circa 2003 - the AKB-23 kit delivers.
