Found this closed bolt GB22 diagram extremely informative and wanted to share. Primarily the bolt carrier group mechanism.

This is the easiest reliable firearm to self assemble on the planet, surpassing even the FGC. It is, however, a single shot without a mag.
I’m aware of how an open bolt version works too as the entire assembly is one solid block that moves forward with a single spring, it makes shell ejection a pain though.

Closed bolt version seems to split the carrier group into two vertical sections with two springs. One controls the slide assembly, the other controls the firing pin.
Mark Serbu is an engineering genius and I will take that to my grave.

Neither are legal to assemble where I live but I like learning how things work and having the knowledge for a rainy day. Understanding a closed bolt mechanism is essential.
Most of you probably knew all of this, but enjoy for the ones who didn’t

What is the most /k/ino Royal Air Force aircraft of all time?

I know /an/ would be a better board but i trust /k/ more.

Every year about this time i have a crop of baby bunnies, wild hares that emerge for about a week. They are juveniles who just stumbled out of the burrow, they are annoying because i have to avoid stepping on them and i can't mow the lawn while they are around.

What does /k/ think i should do? Normally i just pick up the flea ridden things, hit them with a spray bottle of permethrin so they can have a insect free life and then spook them so they learn to hide. Also the Permethrin keeps me flea free, otherwise i'd just cage them and make them pets like Fox kits.

For a few days i can just pick them up, they are supposed to be crepuscular but the babies aren't old enough to get that message, they have a tendency to wander the lawn at full noon on sunny days. I have Great Horned Owls, Ravens and nearby Bald Eagles on my property so a baby bunny needs all the help it can get to survive.

I'm trying to keep them parasite free with the permethrin spray (it lasts longer than they live and affects any other animal they touch) and i'm trying to teach them valuable life lessons, i've got alot of them on my hands.

What is /k/s advice for me defending the Great North Woods Bunnies People Republic?

God this thing makes me drool

Remember the Polaris Spaceplanes guys? They made a partnership with Diehl:
>The aim of the agreement is to equip POLARIS’ unmanned aerial carrier systems with IRIS-T effectors from Diehl Defence. The resulting 'Airborne Launching and Attack System' (AirLAS) creates a new dynamic and provides the armed forces with a full-scale expansion of capabilities. Embedding in the Future Combat Air System or a maritime environment is also possible. First flight tests are already planned for this year.
>AirLAS, with its high potential for future applications, including the possible use in long-range hypersonic systems, will be the basis for innovative solutions from Diehl Defence and POLARIS.
>The main objective of POLARIS is to develop revolutionary spaceplanes for access to space and hypersonic flight. However, we are also leveraging our spaceplane technology to strengthen the defence capabilities of the democratic world with innovative and unique solutions.
My question: would the IRIS-T require a jettable protective cover to prevent damage at hypersonic speeds?

POLARIS Spaceplanes successfully completed an initial flight test campaign of its MIRA II demonstrator. This included the aircraft's first turbine-powered flights and culminated with a roll test of the firm's AS-1F linear aerospike engine. POLARIS are now preparing for the vehicle's first rocket-powered flight.

MIRA II is a testbed for AURORA, a reusable multipurpose spaceplane and hypersonic transport system. AURORA will provide Germany and partners with hypersonic capabilities for research, defense, and orbital cargo.

is 50bmg a valid sidearm caliber?

Post a picture of a weapon that you own alongside things that you enjoy.

I'm not the best at shooting, or golf, or guitar, or painting, but I still enjoy them.

It's been used for all sorts or roles, from anti-armor/aircraft to shooting infantry (or by some hunters for big animals). However, 50 cal isn't designed for soft tissue terminal performance. It usually goes through the target, without significantly dumping energy. It kills because it's still 50 cal but doesn't really use all of its energy.
