Re: suppressor
I'll second the AAC can's, I have one in 7.62SD, basically the same as the cyclone but quick attach.
it's a great can, I've shot it next to a few different suppressors and it is definitely quiter. But everyone will say that their's is the best. Take a look at a few different things when you purchase on. Db rating, and weight. The 762sd also has a break so when you have the suppressor off you still have a break on your weapon. It's a nice advantage. Bryan at Major Malfunctions will have the drop on things. He's good!
Another suggestion is to buy the biggest can you are going to put it on, say if you think you'll be shooting a 223 and 308 but decide that you might pick up a 338 in the future, but the 338 can and use it for everything smaller, unless you have a lot of money, which I don't. Always plan ahead.
