i have an old TRG-21 i was thinking of upgrading the chassis to the Whiskey-3. KRG said it should work but CANNOT guarantee it...since its suppose to fit the TRG-22. (they did not list the TRG-21) So, i'm wondering if anyone here (who has a TRG-21) took the chance and bought it and installed it? Can you share your experience installing it and using it? Will the TRG-21 magazines fit and eject properly? Thank you in advance for any help. EP
The stock base rail is the same part for both 21 and 22. The 22 got slight updates to the bipod mounting slot and a few extra holes, but it is otherwise identical.
