So for those of you who have been following my blog for a while, you might remember a post I made a while back on my Supermaxx 750, here. Well, since then, it has gone though some other modifications.

It now uses a 5" Petg barrel, nested inside an equal length of 1/2" Pvc.
The pump of the SM750 is still not plugged, however I did modify it. I added springs to the Oprv so that it takes more pressure for it to release air. I kinda followed Louie's writeup shown here. The Oprv now "pops" at 4-5 pumps instead of the regular 2 pumps. Now I don't have to worry about my tank bursting if some random kid picks it up and starts to pump it up.
Sadly, after all of that work, I am still not achieving the 80- 90 foot ranges these normally get. I don't know what is wrong, but I suspect it might be my dart fit. I was also told to try a longer barrel, so I might try that too. But for now, here is a fireing vid:
nice job with the rebarrel and everything. good luck getting your ranges up.
ReplyDelete5 inches is too short--I would use at least 6 inches with your 4-5 pump SM750. I used a 12 inch barrel on mine and hit 220 feet per second! Granted, my tank has a leak so I overpump the shit out of it with 7-8 pumps. Check out my mod here: http://nerfbuff.blogspot.com/2012/10/supermaxx-750-mod.html
