So, I've been looking for a new gun, and I have found the AGM M4A1 for 155. What cost am I looking at (realistically) if I want to be able to use it regularly (a couple times a month)? Also, I am not an expert at airsoft guns, so would the replacements be simple enough for a dummy like me? There is also the option of the JG M4 for around 80. Again, cost to upgrade it, including a metal body? Last question: is it possible to install a part that will reduce velocity without spending 260+ on the RA TECH bolt?
Thanks for the help
