2. PBS-5   5.45 suppressor.  Last of the prototypes we designed:

we had 7 prototype designs 6 in 5.45 and 1 in 7.62   For sale is prototype #5 5.45x39mm  adjustable compensation for reducing full-auto muzzle climb.                                                                                    Brief history on these PBS-5’s that we did. about 1997 or Reverse engineered the size and design from a couple of pictures of an original Russian PBS-5
Main changes during mfg were to the muzzle  design and the way the Can was adjustable. 
 The first prototypes 1-4 in 5.45 and the 7.62 went out to  guys in the gun research field over the years.  All Friends.  There was an article in the old  MGN on our 5.45 builds and also in the shotgun news back in the day before the internet went so crazy that it put that stuff outa mass hard copy print business. 
A mfg. we contracted with in Oregon  built the baffle stacks for these from the design we were thinkin about.  A comical angled series of cones. At the time I was not a suppressor mfg. and I am still not.....so Milligan is listed on the can as I contracted the work through him in Oregon. 
The idea was that these prototypes would be adjustable for the angle of the muzzle brake to better control climb. We speculated it was to control the rate of muzzle rise when operating in full auto function.  The adjustment could be fitted to the individual and not just the muzzle reaction from the lands and barrel twist rate among other things and each person tends to fire a weapon a little different. The original Russian At the time in the pics appeared to have a clamp for  attachment or this possible adjustment (all speculation at that point) but not enough info for a proper R&D on that type so the design on ours is a little different   Prototype 5 has Maybe has had about 500 rounds down it because the only difference between it and #4 was the locking lever and muzzle design.  The suppressor  is not as quiet as the final production baffle design that was built for us by Elite Iron but this was 20+ year old tech on this one and as I recall when tested It’s right on the good edge of needing hearing protection but still a good can with the consideration of how open, loose and loud an ak74 or for that matter all kalashnikovs are.  

Attaches to the AK74 24mm muzzle, standard russian or bulgarian thread.  Because its a thread-on design, for or alignment and correct function the host AK74 front sight base faced.
