The MTB 1925 is a semi-automatic rifle of Italian origin.^[1] The weapon uses delayed blowback operation and is chambered in the 6.5x52mm round.

Overview

The MTB 1925 is fed from Carcano M91 clips that falls out the bottom when the magazine is empty, the magazine follower closely resembles that of the M91. The operating system appears to be a combination of delayed and retarded blowback. The massive cylindrical bolt is in two sections of roughly equal size, front and rear. The rear section rotates when the bolt is opened via a spiral cam slot cut into it on the right side (possibly on the left as well, covered by the receiver). The front bolt segment does not turn.

The bolt handle on the right side is engaged only when the large, round knob is pushed in, presumably it does not reciprocate during firing. There is a long, narrow flat plate on the top of the receiver, which has slight fore-and-aft movement, to incorporate a lug at its front that rests in the bolt cam slot, delaying the bolt’s rotation for a very short time and/or rearward distance of initial “dwell”. This plate seems to apply temporary resistance which must be overcome before the rear portion of the bolt can spin open by delayed blowback.
