I own a KWA Sr-12 and have had it for a few months now. I am pleased with its performance so far but I want to make it into a DMR for doing squad reconaissance. I want to give it incredible range and accuracy (as in being able to hit a man sized target at 250'+ with ease). I am planning on using this in OPLCMSS events and possibly in other major operations. This would need to be shooting about 550 FPS -MAXIMUM- using .25g bb's. I plan on using .3's in this because I get both velocity and range. I know FPS is a selling point for most guns but I don't want it going so slow that people can literally see the bb then slap in it mid air. I also want to permanetly disable Semi-auto due to the fact that sniper/recon cannot have an airsoft gun with full automatic capabilities. Also. I am focused on internals. I am going to decide on bipod,scope, and flashhider or supressor myself through specification to specification comparison. For inner barrel I would want either an eDGI 6.01 or a Prometheus 6.03 (keep in mind im not the kind of player who treats their gun like s**t by putting the barrel in the ground when resting or anything like that, so chances of getting dirt in the barrel are rather slim compared to some people I play with. I have an excellent gun tech at the field I play at who will install all of this for me for a fee. Please just tell me what I need internally to make my Sr-12 a DMR. Also I have been searching for a while all over the internet and haven't been able to find exactly what I am looking for because I know that it peeves some of you guys off when people come in here searching for information that is allready available but I am trying to avoid getting off on the wrong foot here. Thank you
