I have been thinking about getting a can for the lapua. Well, I guess I should anyway before they get banned here. I like the Q.D. models, but those are a little more $, or at least the ones that I have found. I have and article about the SRT Shadow, on a ar-30, and the writer was very impressed. but its not Q.D. Another thing, I'm also thinking about building an 6.5 Grendel, or ar-10 260 rem., the 260 rem gets the nod for cost at the moment, as grendel prices have yet to come down. but, what about a single Q.D. suppressor that could be used on either 6.5, & the .338? is that possible? would be nice. Any ideas? btw, off topic, but just got the swaro 1500, and only took it out last weekend, but its pretty impressive. just need a exbal/abc system, and a kestrel... and its no more drop charts, game on!
