are there more roller locked systems

why tho 😦

they're cool

No and no

better than the TT and only like 500 or so for pretty good condition if I remember right

I’ve heard they’re finicky from other folks, at least moreso than a tokarev

why is roller delayed used more than roller locked

It was maybe 200 and works like a charm

Oh

Ok

@Yusako Im pretty sure they are the same thing

no theyre not

gun jesus told me so

oh wait

You have to buy good ammo for the vz52

Russian surplus will work and older spec works

Modern stuff is lowered pressure and won't cycle reliably

roller locking uses the rollers to actually lock the bolt into place, whereas Roller delayed uses similar rollers to just delay the blowback, but doesnt itself lock the mechanism

yes i know

but

why is delayed use so much more often then locked

Toggle lock coolest mechanism
Flapper lock close second

Straight blowback gang

because other locking systems are generally good enough, and cheaper/more easy to maintain/use

120mm blowback gang

also uh, this is me being dumb but

The difference between roller lock and roller delay is not the interface of the bolt but the action of the entire barrel

things like a gau-6 dont need locking cause the barres are fixed so they can turn adn the pressure is safe by the time it does a revolution?

On a locking gun, the bolt and barrel recoil as one unit

On a delayed gun the barrel is fixed

oh so thats how they are functionally different

thank you

The bolts could actually be identical

But whether or not the barrel is fixed would matter

It also can depend on if the action at any point is entirely unable to open

Usually rearward force alone can't unlock the action on a roller lock, and the action reaching a toggle at the rear point separates it

@Yusako https://www.youtube.com/watch?v=12F_am8aumg The bolts do lock up?

o

ohh

Miniguns have bolts

it unlocks when it spins further
