>>61493168long recoil sounds retarded
>>61493192in fairness it made sense to me in the 2nd day without sleepplus i might be able to justify a muzzle device to reduce recoiliunno, it’s the only thing I can think of that makes sense without reducing the caliber
>>61493168>>on a whim figure out how to reduce felt recoil with the extra gasses by slowing down the barrel when it reciprocates backwardsso how does it work, like a reverse long stroke esque action?
>>61493224>it’s the only thing I can think of that makes sense without reducing the caliberlong recoil involves so much reciprocating mass why not a revolver cannon instead?
>>61493247basically a muzzle attachment would redirect excess gasses backwards in order to reduce the speed the barrel reciprocates backwards I just realized that it would make more sense to have some sort of gas piston instead
What if you attached a magnet to it so it would naturally slow down
>>61493444that’s actually not a bad idea to attach at the rear of the bolt
Just buy a lynx and put it on a gimble bro. You're not him.
>>61493383>basically a muzzle attachment would redirect excess gasses backwards in order to reduce the speed the barrel reciprocates backwardsthats a muzzle break, no?anyway, I was bored so I quickly (and badly) drew up a mock up of how the piston might work
>>61493168ur gonna have so much fucking reciprocating mass that it's irrelevant. the over-the-shoulder works in a videogame where you aren't bound by physics, but it moves the reciprocating mass out of line with the shoulder, meaning it'll tend to climb even more. best bet is a fuck-you huge muzzle break that'll TBI everyone withing 20ft. maybe requiring a fully enclosed helmet would help with that.
>>61493444>>61493535been tried, doesn't work. maybe you could do it with extremely powerful electromagnets, but not permanent magnets.
>>61494209>ur gonna have so much fucking reciprocating mass that it's irrelevantI always wondered about going the other way, some kind of recoilless .22lr that you could hang on a gimble on a drone.
>>61494209that’s actually why I wanted to double-check if my recoil mitigation idea was feasible much less practical
>>61493168>>61493383>>61494024Congrats anon! You reinvented gas delayed blowback, but cludged onto long recoil!Sarcasm aside, it is a cool idea. I wonder why gas delayed isn't used more generally? Compared to roller/lever delayed or conventional locked systems
>>61493168>on a whim figure out how to reduce felt recoil with the extra gasses by slowing down the barrel when it reciprocates backwardsSo, a muzzle brake?>side effect is that it vents near head you fucking what
So if the shoulder mounted one is 20mm, does that mean the sentry one is 30?
>>61495771holy based
>>61494438recoilless rifles require you to spend equal energy in both directions, so you'd be left with a half-power .22lr
>>61496424My idea was to put the action in a carriage on a rail with a slow spring (or pneumatic piston or something) so that the recoil was buffered over a long enough interval for the props on a drone to be able to compensate it, possibly with a pusher prop just for firing stabilisation that pulses with each shot.Failing that, an actually recoilless rifle style action so in that case, maybe size up to something with more kick but ideally the felt-recoil stays under what a drone can absorb, since recoilless rifles aren't usually 100% recoilless.
>>61493444what would this do that a spring couldn't
>>61494024Look, someone added a spring to the French 75.
>>61496472not him but I agree. Just some strong af springs
>>61495024>gas delayed blowback, but cludged onto long recoil!the fault lies with me for my shitty drawing, but its not actuallythe piston is vented, in a similar manner to a hydraulic shock absorber
>>61496807>[ENHANCED]
>>61496448a drone can absorb 5.56 recoil just fine. there's a bunch of companies slapping AR-15 gimbals on octocopters. you're not going to be magdumping anyway
>>61494438A gyrojet would work better.
>>61497523>an actual use case for the gyrojetMake it at least .50 cal HE and you're in business.
>>61495771if you look at the case dimensions it's closer to 50mm. they are BIG.
>>61493168>>tfw I might have made a minor advancement in recoil reduction at the cost of vaporizing infantry facesJust vent it towards their crotch.
