Hi... I have a quick question some of you might be able to help me with. I've got a Accuracy International .338 Lapua with an AWC Thunder Trap (338). The threads are M18 X 1.5mm. I also have an LWRC 308 threaded with 5/8 24tpi for the muzzle brake. The obvious question...is there a way I can get my Thunder Trap on the .308? I hear a lot of people are using their .338 cans on 308's as well. It appears I would need a thread adapter to go from my 5/8 24tpi to a 18 x 1.5. Does such an item exist? Is there another way? Am I seeking the impossible? Thanks for your time and response if you have the time. Regards, Gavin Morrison, Dale City VA [email protected]
