A few pictures to show the differences between HK MR223 vs. JP Rifles CTR-02 (AR-15).

You're welcome to share my pictures on other forums.


Changed the uppers / lowers on the rifles.

Won't fit!

It's interesting how wide the HK hammer is in comparison to the JP. Thanks for sharing the photos.

JP hammer is narrow even compared to standard AR15 hammer. This makes it very light while maintaining proper height.

3-Gun, have you tried the JP yellow springs with stock MR internals?

Has anyone else tried this with their standard AR's? Is this a problem only between the CTR and MR?

This is MR223 - it has receiver pins relocated by purpose, to make it incompatible with AR15 upper/lower (namely with HK416 upper/lower). It only applies to this version, MR556A1 is compatible with AR15 uppers/lowers.

Got it. Thanks Montrala.

No. Don't think it would work. But please correct me if wrong!
