So, I'm not going to get much from fitting one, although I like the idea of 2 or 3 shot burst, but I'm now a little confused about precocking!
I completely understand the theory behind it but my MP5 has a specified rate of fire of 700 to 850 rounds per minute. Even if that's wildly overestimated and we say 600 pm, that's 10 per second! Each shot is a tenth of a second! Are you telling me that you can really notice a difference or is it something we tell ourselves because we have a need to fettle/upgrade to make ourselves feel better?
