I saw the Siren and Nightbeat guns last night, pretty tempting. I still have mis-matched parts between Nightbeat and Minerva.
These parts are from this guys website - http://www.goodtogocustoms.com/alyoshascorner/index.php in the 'robot changer' sections. I think he posts on the Tfans forums.
These guys do nice work elrod is a top notch guy, check the website for a custom bludgeon fig. Just a heads up long seeker missles and HM Seats are comin
Somebody needs to start reproing Targetmaster guns and Headmaster heads. Preferably, with Targetmasters with the new size standard 5mm pegs.
