TAG and GTA have some positive reviews and then there was an extremely negative review of a pre-production gun by a Dutch bloke that seemed rather biased to me. The design is rather simple but I see that as positive as long as the trigger is good, haven't shot one so I can't tell how it feels. CZ barrels so there shouldn't be any problems with accuracy and pullback front cocking is a nice feature. Shroud is way too small and needs a silencer with odd threads to make it work (unless they have changed that since). If I needed another bullpup I'd be tempted to try one. It is actually rather similar to a Colibri as far as features go and people love those guns.
