Update:
Gamed the M60 for the first time on Saturday - fired about 9000-10,000 bbs and it worked beautifully until I sheared 4 teeth off the spur gear!
Upon closer examination it looks like the grease I used on my piston, piston rails, tappet plate, and nozzle either froze or got very thick (think dried wax). I ran out of my usual grease and used some stuff I had lying around... Guess I'll toss that stuff lol. I also burned through 4200 MAH of batteries, and only had an 11.1v Lipo for a back up that day, which brought the ROF to around 150% of what is was on my 9.9V LiFe batteries, I believe this also contributed to the failure. However, this would have just been a matter of time, and would have likely happened later this year anyway.
Solution? Ordered new grease and Lonex Enhanced Super Gear Set - High Speed Ratio (16:1). I'll just replace them all to prevent any future issues. The gears are also 16:1 over what I assume is 18:1 for the A&K gears. I'll fine tune the ROF with my Gate Mosfet but this will give me more flexibility to get an optimal ROF with reliability.
Other than this, the gun worked beautifully once the hop up was dialled in. Range was lacking but I'm estimating 160ft before the bb dropped. I would like to see 200ft consistently but range is secondary to reliability. On this note, the gun worked well, but the box mag began showing it's flaws:
1. Jamming. I had it jam on me twice. I think I have a solution - more to come.
2. The box retention system is crap, utter crap, when running with any weight in the box. Because of the mass in the box it will dislodge and hang on the spring feed tube and lower retention strap when I run. On this note, it also sags under weight and kinks the spring feed tube. Half the time I had to plant the bipod and hold the box in place for it to feed.
Solution: Bolt the box mag in place via 3 bolts and metal plate to clamp it in place. This combined with the straps (which won't end up doing much of anything) should eliminate this problem. The hole in the fabric box and plastic box also do not line up properly and this contributes to kinking the feed tube. The hole in the box will be enlarged and a grommet added, this should lower the tube and provide more efficient feeding.
On this note, I also bought a Condor Flashbang Pouch for externally mounting my battery on the front of the box mag. I much prefer this over mounting it on or in the box itself.
More to come on that.
But pics from the game!
On the defensive, falling back to our objective:
On the offensive, M60's clearing a path!
After the gun went down, trying to hold an area with my pistol while our squad pushed back, got taken out by a great grenade toss. Buddy filled a Thunder B with bb's and had it perfectly timed for an airburst right over my head haha.
