Hi Martin , thats a shame on the ammo strip , but like Paul says mate got to heat it up to bend it a little , a bit at a time with the heat gun dont want to melt the abs , have the heat gun about 8 - 10 inches away from what part your bending , and i would say a max of 15 seconds up and down with a nice controlled speed , and after 15 seconds start to bend it in to the desired shape might have to do this a few times , then move on to the next inner bit between the ammo boxes , i hope that helps mate , if any probs just ask on here , i know i made the same mistake myself , but Pauls offering you another , because thats the kind of guy he is the best in the hobby as far as iam concerned .
Oh yes i forgot how good them photos are of my TM 1mm
