I have 3 pretty crazy ideas half assembled on my work bench. For now, here's one. My DIY recoil reducing stock for side charging upper. I cut the buffer tube to allow for more travel.

That spring stiff enough? I forgot there was some slop in my RASS rest during recoil, and I crawled the stock while looking through the Quadrant’s peep. First shot hit my glasses hard enough to fold the rear peep shut and scratch the shit out of my glasses. Lesson learned. |

That is food for thought. More machining than I’m able to do though. For now I’m leaning towards a heavier tube if the 16ga wouldn’t be enough (it still might, I just dont know one way or the other). I got a quote for the heavier walled stuff. I’d be okay with the $225 price, but the $60 they tack on to simply mail out a 3’ tube is kind of insulting. https://www.AR15.Com/media/mediaFiles/53338/F07BAFBB-F007-4BDB-9749-6B4E607B32D6-620240.JPG I could probably tighten the bore up with chrome.

Make a section at the bottom (maybe 3" long) that is thick walled and has the chamber and the ported tube for the blank. This can be the same OD as the 16ga tube, but with a smaller ID. Make a cap/plug between the high pressure and low pressure sections and port the crap out of it. Make a stand off so the can does not sit on the ported plate, but 1" to 2" above it. This gives you a thick section to take the pressure of the blank, a section for the gas to expand and a baffle to slow it enough that it wont burst the can (hopefully!). Just a spitball idea. You might be better off with a really thick wall (1/2" or so) so that it would reduce the volume in the first chamber and provide more gas volume for lifting the can.

16ga in that diameter can get dinged really easy in transit. I can see them charging to prevent that. Most of the time it is better to get stuff local, but seamless stainless tubing is a bit of a bear to find local in small quantity. View Quote View All Quotes View All Quotes Quoted:

Got the BCA side charging upper just a bit ago.
Overall, not bad. Upper is billet, nicely machined with a smooth anodized finish. No fit issues at all. PA, was out of the threaded plug for the rear of the upper. The threads are 7/16-14NC, I might get a bolt and make my own, not that its needed... BCG seems well made as well. Smooth nitride finish on the carrier and cam pin. The bolt is a typical MPI marked generic bolt, again I see no issues with it. I did check head space with a GO and NOGO, passed. The BCG rides smoothly in the upper, no binding at all. I did add a little vibra tite on the bolt handle bolt threads, if it loosens, I'll hit it with blue loc-tite next. My wife really likes it, much easier for her to charge, $120 well spent |

I was thinking at first about threading the tail tube directly onto the bottle (started a thread looking for a soda bottle thread tap here: https://www.ar15.com/forums/general/Tap-set-to-match-soda-bottle-threads-/5-2132031/ I’m not having much luck on that idea yet, but they did link to these: https://www.infiniteproductsolutions.com/adapters/bottle/?sort=featured&page=1 I like those, but the beer bottle adapter weighs over 4 ounces (according to their website), while their soda bottle adapter is about 2.5 ounces. Attached File You could screw an adapter onto the 16oz bud bottle and have a short nub threaded into it and sticking out the back. That nub could be metal, and then just glue the fin section’s center tube to it. That way you just unscrew the assembly off of the beer bottle on recovery (bottle destroyed) and put it on a new one. If the fin section gets broken, then just peel it off the nub, and glue a new one on. I really like the thread adapters being metal so they can be reused over and over, but the weight is a drawback I think. Your printed adapter would be great in plastic, I just have no idea how many landings it would survive? I dunno. ETA: I’m also thinking about maybe silicone bands for obturator rings. They sell them in many different diameters and they’re thicker than rubber and likely more durable than either rubber or neoprene. They could probably be reused many times, and they are cheap in bulk too. Attached File |

I was happier than a puppy with two peckers all night after getting the mortar parts, but after I set it up this morning and got a good look at it, I’m kinda screwed. There isn’t enough meat in the yoke or barrel collar to ream it out for a can cannon barrel. I thought there would be, but apparently they tried to keep the weight down on the 50mm sets. Mounting a 66mm bored tube on this thing will take some serious surgery.
I’ll have to think on it a while... It has a fake tube and cup on it right now. I’ll have to clean it up. Attached File |

Cool, standing by for details.
I stopped in Lowes to look for tail stuff. Didn’t find a lot, but one possibility. A 1” threaded pvc connection fits almost snug on a 16oz budweiser cap. So I got a 1” threaded-to-3/4” slip fit adapter and some 3/4” pvc pipe. I still need some flat pvc for the fins (they didn’t have it at Walmart or Lowes). I’ll have to order it I’ll epoxy the budweiser cap into the pvc adapter, slot the 3/4” pipe for fins, and glue fins in when I can make them from sheet. It takes two silicone bands to snug the bud bottles in the launch tube. I’ll have to find some thicker bands. Attached File |

I took a Coors bottle shaped can, dumped the "beer" and refilled it with a 3x expanding spray foam - the intent was to lighten and stiffen it so my son can shoot it more comfortably.
"Worked" sorta. Can/foam was of course very light so it had near zero recoil. Didn't travel very far - like 30 yards. After the first shot (pointy end loaded down), it collapsed a bit on itself uniformly, like it was in a vacuum. Held its shape well enough for about 10 more shots before it tore enough to expose the foam and we switched out for another one. Best part was, it was great for nailing targets at fairly close range without much risk to the target, can or shooter. Son even suggested we get the welding helmets on and have a "nerf" war. Gonna try it again, but first weighting the bottom of the can with sand or similar ballast, then the foam. Hopefully can dial in the right ratio of mass to recoil to get some range back while still pleasant enough for mini-me to blast away. |

OK all, here is my findings for today. First: my inverted spring loaded stock worked GREAT for my shoulder. It took the recoil down to where I wasn't aware of it in my shoulder area. The only drawback was that I was now getting a nice jolt in the wrist due to rapid backwards movement. But it was not as jarring as the steel stock was. I call it a win so far. I am thinking about getting something like an automotive valve spring. About can "loads." I didn't have a super heavy loadout. just 24 8 oz cans, 10 of the coors bottles in the green paint, and 6 of the 8 oz cans glued to empty 12 oz cans. One of these cans I made some hasty fins with a utility knife. This was for the LULZ, but it turned out to be pretty good. I'll get to that later. First, the 8 oz can, tab in performs the best as always. It gets the most distance, and seems to land within 10' of the same spot each time. Not too shabbty. Today I was getting about 115-120 yards with the barrel aimed at approximately 40º Here's a iPotato pic for distance reference. This is from the impact zone to the table I was shooting next to. Attached File Second: the 8oz cans glued to empties. I was very impressed with this setup, and I would recommend it for anyone looking to try and stabilize the can for accuracy. It performed exactly as I had imagined it would. Distance seemed to be slightly less than running bare, and I think it's because it's changing trajectory in flight as the heavy part of the load spins to move forward. Can launcher test. Here's pics of it happening as I anticipated. Attached File Attached File Attached File Third: The Coors cans are a cool looking dud when filled with water. They didn't make it too far, and that was disappointing. Emptying it out a bit produced good distance, but it was very erratic—changing flight angles mid flight. Forth: the single finned can load. Because of @Desert-AIP, I made this. I thought it would be a bust, but it was not! Shasta Blasta 7/29/18 Attached File Fifth. I have gained some weight since I last took a gun video. I'm thinking it's all these Coors. |

If I don’t hear from Jeff at F5 in the next couple days I’ll give him a holler and see if he can do anything. |

last year, in a now-deleted video "the king of random" made some silly potato gun, and 3d printed projectiles. https://i.pinimg.com/originals/07/cd/6c/07cd6ce22eede69e2ff94068d7eb75d3.jpg Projectile was hollow, filled with black powder, and a primer inside right behind the nose, which had a small opening for a nail to protrude. Nail impacts target, sets of primer, sets off black powder, makes a nice white smoke show. What was the ATF limit on explosives again? View Quote |

I think 20" is what I'd like to try out. I am also going to start scoping out the mexican/asian groceries for oddball sodas in steel cans. That alone will be a game changer regarding how much pressure they can take. |
