Quote HistoryQuoted: That’s pretty much the exact set up I plan to have. I have the side charging upper and carrier. Just waiting for the can launcher. Any chance I could commission you to make another plug? That looks great. Did you by chance use the bear creek side charger? |

Quote HistoryQuoted:
I also have the longer 11” barrel: 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... ? Quote HistoryQuoted:

Another thing for people reading this.
I was an early adopter and have probably launched 1,000 cans. I can tell you with great confidence: FOR BEST RESULTS LOAD THE CAN TAB-SIDE IN. That means the part you drink out of goes in oriented towards the rear of the gun. They explode in the tube the other way. I think most people believe the tab is going to blow open, but it doesn't. The aluminum is much stronger on the lid vs the base which is thin and will fail. |

Quote HistoryQuoted: I have pondered this for a while now. The best idea I can come up with is something like a flat plastic sheet bent in at the back of the can. Maybe around the neck of the aluminum bottle and held by a rubber band. Then there would need to be a wad that was tethered to the band that would disengage with the launch. A simpler way to do this is to have an empty can epoxied to an 8 oz can, stuffed into the tube backwards. I would wager it launches like a shuttle cock. But a canister missile has curved fins that hug the body in the canister. They are spring loaded. When the missile clears the canister they pop into place. (looking for a video to illustrate)

Buuut.... maybe it gives a softer push at the start due to having a larger space under the can/projo...? Aaannnddd.... mayyyybbbbeeee..... that could reduce range slightly? Purely prognostical speculatin’ though.
Well dang. I don’t know if I should bother to send the short barreled uppers back. 
Both lengths place a 12oz can at about the same distance below the muzzle, and the longer tube just leaves a larger space that needs pressurized under the payload. |

Skillets: good stuff man.
I’ve been wondering about using a sabot as a tail. Maybe stack some bore diameter cardboard disks (glued together in a 1/2” stack) that is tethered to the base of the can by a cord that’s glued on? The cord being maybe 6” long? The sabot would cushion the shock on launch, then maybe the drag of it following behind (at end of 6” tether) would keep it oriented? |

Nahh. I have a a few days off from work and I am using that time to tinker around in my shop. Plus, having these cans around unpainted makes me want to put them in the recycle bin.

Two questions (maybe three) regarding the Coors Light 16 ouncers.
Lid in or out? Full or no? And if they’re only partially full, do they flip end-over-end in flight or fly true? Seeing as how I love the can cannon and Coors Light, I’m a little embarrassed to have to ask.

Quote HistoryQuoted: I’d love to, but I’d need your specific upper to fit it right. I turned the 3/8”-16 threads in the end of a square rod of 7075-T6 and then screwed the threaded rod into the receiver. Then I had to measure the angular offset and set the shoulder back on the threaded rod to time it to the receiver... Only then could I continue contouring the exterior surfaces. Sounds like a lot, but only took about 2 hours but I did need the receiver for the fit checks. Did you by chance use the bear creek side charger? Thanks for taking the time to explain. I did order the Bear Creek side charging upper and bolt carrier. When deciding on Bear Creek, I did notice that they made a plug. It was not in stock but in looking at comments about it, everyone says it is timed wrong and does not fit right. Good news is I just got my shipping notice today. Wanton can destruction, here I come. |

F5 emailed me letting me know they have already shipped the 5 long barreled uppers to replace the mistaken 5 short barreled ones. They also emailed me a Fedex label to return the shorties. They said “no rush, when you get a chance”. Hopefully the long barrels get here quick, then I can do a side by side comparo with pics.
F5 seems relatively on-the-ball so far (considering their size and the fact we probably swamped them). Jeff (Jeff Milton “[email protected]”) is pretty quick to respond to emails, and even answers late hours ones.

Seeing as how I love the can cannon and Coors Light, I’m a little embarrassed to have to ask. If I had to take a wild guess, I would say that regardless of the orientation when firing, they will flip around to where the cap is facing backwards. It's not going to matter much though. I filled mine up all the way to the rim because I didn't want a bubble to make a weak spot. But I am now thinking this might have the opposite effect and blow apart from water hammer. |
