I don’t think it identifies as a carbine any more 😂
Probably the most problematic build I’ve had, but it’s finally done!
Umarex G36C with a custom barrel extension (It’s about .4” too long 😬) Kurz style gas block, Ultima H-Key rail, SOTAC (I believe) EOTech and magnifier and a LLM when it arrives.
Stock needs drilling to fit as the Umarex one isn’t correct for the impression, hence it just “resting” and the fire selector markings need removing and replaced with the “SEF”
