I have Legends Gun Truck conv LF1034 and the mini gun's barrel is warped is there a technique i could use to straighten it. Or is there a plastic version of the mini gun I could purchase.

You could possibly ask for a replacement from Academy's Pavehawk. Or.. I have two of the Legend's mini gun sets I've decided not to use.

There is a small version with DML's OH-6A.
You can try heating the barrels in hot tap water and straightening it then dipping in immdeiately in ice water.
Or, you could get insane and replace the barrels with stretched sprue.

The hot tap water works for me. All of Legends barrels seem to come warped. I wish there was another source for these guns in 1/35.

Ill give the hot water trick a try. If they would pack them a little better it would help. Thanks.

YA i'll agree i think i have 2 of like 8 ot 10 that are fairly straight....................
