Finally got around to emailing volquartsen asked if the tg2000 for l.r. would be all right to use or if you need the tg2000 magnum trigger here's their response. If I remember correctly wheeler had to modify the his trigger group(file down the bolt release I think). Use your own discretion and good luck.

Kevin,
It should work however the biggest difference between our LR and Magnum trigger guards is the length of the bolt release. The magnum version is slightly longer than the LR version.
Both versions should work in that rifle though.
