Jim Gravitt can be reached at Protech engineering (217) 335-2727. While he does build HK 21s you won't be able to build one from a kit and 91 receiver if that is your plan. You will not have a box feed mechanism housing and Jim nor anyone else does not have the specs. for that part. You will be able to build an HK 11 however.
Good man, he did my MP5-N.
A mag fed hk21. Or a better description, basically an G3 with quick change bbl, reinforced receiver, 1200m sight, hk21 stock, and other fixins.
