Got a question for fellow TD owners. I bought mine two weeks ago, shot great, broke down great, shot it again the next day, then went to pull it apart and it was really sticky. Cleaned it thoroughly, shot it this weekend, and was really sticky coming apart after I was done. Does anyone know if this is a heat issue with the metal expanding right after shooting, or just gumming up from shooting? I put probably 100 rounds yesterday, nothing major. Other than that, it shoots great, I think my rear sight is off a little bit (not as bad as I've seen in pictures) but with the scope this weekend it was great. Any help is appreciated. Thx.
