I am looking to purchase a Gemtech HVT QD can for my 5.56 AR. I want to go with the bigger can so I can use it for multiple applications and I know there is about a 2db or more difference when using a 5.56 round with a 7.62 can...no big deal. My question is that I have to use a 7.62 flash compensator in order for the HVT Quickmount to fit on the 5.56 barrel. What effect does a larger bird cage have on the smaller caliber 5.5.6? will it work as well as a smaller 5.56 cage or is there a difference? (of course I am talking about firing the rifle without the can attached).
Anyone here have any experiences using larger cans on their 5.56 barrels?
