I had been kicking around several ideas to make myself a more user friendly woodsball marker for myself. My requirements were very basic. 1: I wanted a side deeding body. 2: Simple design 3: Easy maintenance. After kicking around several cantidates I settled on one of BT's new Mini based TM-15's.
Here is what I started with:

I knew form the start that I wanted to shorten the foreguard. So I took the front down to the second internal body baffle. I used a fine metal hacksaw and mitre box for the rough cuts. Then I bolted the clamshells together and dressed the end nice and square/smooth with a flat file. The detail areas around the picatinny I did with a needle file. A quick buff with some 400 grit wet sand and it read to paint.
I used Krylon Fusion CAMO paint. Their camo stuff is really tough and fairly flexible. Much more so than their regular Fusion colors. It also dries really flat. I did very little body prep. A light scuffing with 400 grit and a wipe down with paint thinner (mineral spirits.) Everything got several light coats in either tan, olive drab or dark brown. I painted the rails first. Then masked them off an did the rest of the body. I finished off the detail on the fire modes with some Testors model paint and a toothpick. I used a flat stiff bristle brush for the TM lettering.
So then it was on to the box magazine. This was the reason I wanted a side feeding marker to start with. In an age of force fed hoppers a top loading marker is just dumb. I got the inspiration from Oily's M249 box magazine. Props to him for being the pioneer. I decided to use an Airsoft mag since it would require little modding to fit the mag well on the TM-15. The steel mag took some Dremel work as the retaining slot was off a bit. The interior also too copious amounts of Dremeling to remove all the Airsoft guts and dividers. The plastic its made if is unbelievably tough. I used a couple of 3/4" copper elbows for directing the paint from the chopped Reloader B and into the marker. I used a cut 140 round pod for the feed port. This will eventually be widened at the neck with a speed feed. Epoxy was used for all the bonding work. The last thing to do was mount the board. Having access to it was an issue. So I decided to cut the back off of the Reloader B shell and make an external mount. It plugs in via slot in the back of the mag. Test firing with 6 AA's keeps up with the 10 bps full-auto setting on the TM-15.
So without further ado here is the (semi)finished result:
