I have zero experience with suppressors, but am looking at getting some in the near future. These are only for convenience and recreation so I'm want good quality but I don't feel the need to invest thousands.

Based on specs and price, I kinds like what I found from Yankee Hill, but I know nothing about this company. Are these good quality?

Second, can a supressor be used with 6.8 spc? I'm guessing that a .30 caliber might work, but I'm not sure.

Finally, are there any issues with using a gas piston conversion with a supressed AR?

Thanks for the help.
