    Spendy little round things

    So i know titanium is expensive to make, and hard to machine. So saw the price tag and went yikes. But if you wanna play you gotta pay. So i got the ak left hand thread, and the 308 thread. The top of the cap just screws in on the Ak threads like a normal system. But that little plunger you gotta depress does kinda need a home. So if you are gonna use this. Make sure you keep tightening it up because its not gonna lock in that tab and could back off being straight. Or i guess you could just dremmel out a few grooves on the face to add character and detent points.

    The thread protector and end cap just seem heavier than I expected.

    Machining work was excellent. Threads, knurling, and finish looked great. All pieces fit together perfectly including cups.
