Ultimax 100 Saw/lmg

Cocked&Locked said:
Not exactly a long recoil system. In long recoil, the barrel recoils with the bolt the full length of recoil, the bolt is retained, the barrel runs forward extracting the cartridge, then the bolt is released to run forward and chamber the next round. In the ultimax, the barrel is not recoiling with the bolt. The bolt is however given more room to stroke backwards so it does not impact the rear of the reciver, giving a usefull rate reduction as well as enhancing controllability. The only mechanical impact imparted during the firing sequence is the bolt striking the breech face and locking, which will have the effect of forcing the muzzle down and countering (somewhat ) recoil.

Correct.Thats what I meant when I wrote "as do some antique machine guns".I could have been more specific I suppose.

you need to do better than "duh we already have open bolt semi's..." try looking at the trigger mechanism then figure a way to make it semi. then try and find a way to make it fit in the rifle.
