Hi. I've just purchased an old G1 Prime gun so that I could display Rollar with the thinner barreled rifle gun that never fit in Primes hand properly, and have Prime hold the thicker gun that came with him. HOwever, much to my surprise, the gun handle on the thinner barreled rifle is just too big to go in a standard sized hole like on my TFC Rollar. I'm not a customiser or a modder. I was thinking perhaps wrapping some sandpaper round the handle and twisting until it filed down the piece might be the way to go to get an even circle. What do people think? I realise it's going to ruin the paint, but the gun handle will be inside rollar or someones fist or on a jetpack for the majority of the time so that shouldn't matter. Is there an easier or better way of doing this?
