MR1's are like Tonka Trucks, they never ever break. You have tons of upgrades for the MR1, sky is the limit. Go to the thread "Show your MR1" and get some ideas from there, as far as internals, go with a Derlin bolt, change the velocity spring, the expansion valve, polish the internals etc.. As far as barrels don't buy anything longer than 14", is terrible for mobility and i just a waste of air. Hope this gives you an idea...
