I was thinking the same thing. What about using a plug made from wax? I'd think that would melt (or just burn up) and be relatively clean. Quote HistoryQuoted:

If you have not yet tried soda can skeet, DO IT!!!!
Third shot with the can cannon this morning, I about fell over when the wife asked if she could try 
Of course I agreed, gave her the can cannon basic training course and grabbed my TAC-14 
She fired off a 6oz can, then giggled as I proceeded to miss it  She said it wasn't as bad as she thought it would be and asked If I wanted to try another can, HELL YES!!! Again, a miss. At this point I had figured out why I was missing, the can hauls ass for about the first 30-40 yds. So, It was near 50yds before I was on target and firing. 14" barrel, cylinder choke and #8 birdshot is not worth a shit at 50yds.....
I had my VR60 auto with me, shoved in a full choke, loaded up the mag. We had 5 cans left at this point, I didn't bring all that many as I figured I would be the only one launching them.... Wife shot the can and so did I Not a perfect hit but at least a few pellets hit causing a spiraling spraying of soda before it hit the ground. Same thing with the next can. By this time, I was getting the hang of tracking the can quicker. 3rd,4th and 5th cans were all solid hits, Like hitting a clay and turning it into dust, only exploding, wet mist

Well, Since it looks like it's going to be "Hate on F5/XProducts" time again, might as well share.
After ordering on Sunday the 1st when their website said 13 were in stock, I still haven't gotten anything. I got immediate notification that a shipping label had been created, could see it on USPS tracking, (still can) and no updates after that. I contacted their customer service through the website contact form on Sunday the 8th, figuring a week, especially considering the 4th of July holiday was Wednesday, was a fair lead time before I started asking questions. I'll note that friends here in WI with me that ordered one on Monday the 2nd had gotten theirs by Friday the 7th... 
I was initially encouraged when Jef" contacted me via email rather quickly by the morning of Monday the 9th, and said he'd look into it and promised me an update sometime in the latter half of the day. He did not respond until 7pm Central my time, 5pm Pacific his time, and that was after I'd prompted him with another email. He said they'd been having problems with USPS and to give it a few more days. So I gave USPS two more days to deliver, Tuesday and Wednesday evening. Nothing. So I contacted him again Wednesday evening after the mail had come, mentioning that I had hoped to use the Can Cannon at a cookout/shoot with other Arfcommers this coming Saturday the 14th (tomorrow) and that almost two weeks seemed more than enough time for it to have gotten to me. And I further mentioned that I'd only really be able to use the Can Cannon at such events, because my neighborhood is far too urban, and my gun club would not allow it. "Jeff" promised to ship one out via FedEx so it would get to me by today. Nada. And now it's Friday night, and I didn't receive any tracking information, and FedEx has nothing on their website's delivery manager subscription page indicating they have anything in transit for my name and address anywhere. So if Jeff or anyone else from F5 is reading this, I don't think F5 is being "rude" or "mean" intentionally here, but I am pretty certain at this point that you are a bunch of fuckups.  |

another thought, for the more machine tool savvy guys here, The way I can see this done is on a mill with a 30 degree double angle milling cutter, or maybe a really thin slitting saw, and a rotary table. to make a miniature version of this
 Attached Filethat could be used in place of the seater stem in our conventional dies. Ideally a CNC setup could crank them out faster than a manual, but the problem of cost of scale to manufacturer is still going to be there no matter what I am afraid, hell if someone wanted to absolutely own what little market there is for this they could have a billion of them done in MIM...but would probably have their grandkids still selling them 50 years after their death. One other small PITA, I would bet dollars to doughnuts you would have to anneal the brass every time as well. Hell if I get my lathe back together I may just grind a file down with a safe edge and waste away a day in the shop. |

Update on my order: called the Modern Manufacturing number, the guy could see my order, and said he shipped it out when FedEx says the label was made. Since FedEx doesn't show anything after the label being made they probably lost it. Said he's had trouble with both FedEx and USPS having long delays and losing stuff.
When I mentioned that I had been hoping to use it at a get-together this weekend he said he'd just ship another expedited so I'd have it in time. If I end up with two I'll just send one back. I asked if they were slammed over the last couple weeks and he admitted we had pretty well cleaned them out  but he still wanted to take care of everyone and sort through these issues. Seems like a guy that really cares about customer service and is just overwhelmed with orders.

SWEET mine arrived. Took 8 days from order to delivery.
Mine WAS NOT hand tight. I had to use my oil-filter strap wrench and a action-rod to free it. I cleaned the nub up, deburred the chamber lip, polished the chamber with some abrasive polish and a cordless drill, and reassembled the barrel onto a Bear Creek side-charging upper with about 20 FT-LB of torque. The side charging upper was $75 and the side charging BCG was $60... LOOKS great. I have an Evike picatinny mount quadrant M203 sight (air soft) on order and I'm trying o get the custom laser engraved 80% lower for this thing made. In the meantime, it's sitting on another lower with a PA red dot on top temporarily. I even made a little custom plug and then blackened it to much more effectively fill the unsightly plug typically found at the rear of side-charging uppers.

I have an Evike picatinny mount quadrant M203 sight (air soft) on order and I'm trying o get the custom laser engraved 80% lower for this thing made. In the meantime, it's sitting on another lower with a PA red dot on top temporarily. I even made a little custom plug and then blackened it to much more effectively fill the unsightly plug typically found at the rear of side-charging uppers. https://www.AR15.Com/media/mediaFiles/132797/D3421B4B-EA53-426F-843C-559A6D83710F-611449.JPG https://www.AR15.Com/media/mediaFiles/132797/ECE3A842-2CF1-4F5F-B646-DD5623CEDB71-611450.JPG https://www.AR15.Com/media/mediaFiles/132797/7A706EDF-3335-4491-814B-900BDD4ECD56-611451.JPG https://www.AR15.Com/media/mediaFiles/132797/0B476DAA-AE12-4170-AEE1-4CA4AB8326AD-611452.JPG https://www.AR15.Com/media/mediaFiles/132797/6610AEB4-164D-4455-9888-91E20A2941F4-611453.JPG

Attached FileETA: if the 11” launcher barrels have the same length 5.56 blank barrel inside, then the only difference would be the internal can stop shoulder, and if that’s the case, then they are wasting 2” of payload space...? I’m confused why they would do that? |

Ok, I got home and started measuring. Something weird is going on. My 9” barrel also sits a 12oz can 1” below the rim. They must be be using different internal dimensions on the two barrel lengths....? Gotta be.

I’m confused why they would do that? 12oz can sits 1-1/8” below the tube muzzle The step in the bore is 7-5/8” from the tube muzzle The distance from the step in the bore to the back of the tube is 10-1/4” The tip of the barrel nub is 3-5/8” from the front of my receiver rail. So yes, it looks like the longer barrelled version has the same payload space and an extra 2” of expansion space behind the payload. Lame. Only reason I got the longer version was to fit more tennis balls. Oh well. I can only imagine more barrel space behind the cans means lower pressure hitting the cans? So maybe fewer can ruptures. But with the same effective barrel length and a lower pressure acting on the can, I also imagine that can wouldn’t go as far... so wouldn’t the short barrel version be able to launch cans a tiny bit further? Or what if I put the longer barrel in my lathe and walk beck the shoulder about 1.75” or so... ? |
