Question: Do our military personnel / employees use the AR platform in the SMO?
Answer: Yes, and this also applies to carbines chambered for 5.56x45.


   As for the pros and cons, the main advantage of ARoids (besides the show-offs that no one has cancelled) I see the ability to use any modern optical and optoelectronic sights without increasing the mass of the weapon due to various bracket adapters and fears for the "floating zero" .
   And the main disadvantage is hunting ammunition, which does not penetrate any bulletproof vests at all.

   An AKMS assault rifle with a 1P87 "Valdai" sight installed by a reconnaissance officer of one of the units of the Special Forces of the Russian Armed Forces in the SMO zone in Ukraine.

   The use of weapons caliber 7.62 (AKM, AKMS) in the presence of standard AK-12s is due, first of all, to the presence of standard devices for silent shooting - PBS-1, not many of suppressor are avaliable for AK-12. For this reason, oldschool comes into play.

   The use of commercial "cans" for assault rifles in caliber 5.45 (AK-12, AK-74M, RMO, etc.) is an investment of your money for the purchase, and most importantly, the production time, which is currently shifting to the right . This is in a situation where "cans" were needed yesterday.

   All this forces the scouts to turn to carabines in caliber 7.62 in order to at least to some extent compensate for the lack of "silent" guns in the unit.

 

Also note that AK-12 have its own twist and needs specially made cans for it.

SR-3M. Not much on this one. Controls and guts are same as on AS. Interesting note is that SR-3 (not M) had stranger charging handle, different safety selector.

Question (probably for @Sturgeon), how does the trigger connect to the bolt in a bullpup rifle so it can shoot? Is there some kind of extension rod or a clever bolt design? 

 

depends on the specific gun, but typically you have a normal rifle fire control group in the rear which the trigger is connected to by a long (and frequently unfortunately flexible) rod.

some bullpups are different, however, like the RDB, which has the fire control group close to the trigger, and actually telescopes the entire hammer around the bolt group.

   Today is the birthday of I.Ya. Stechkin. Here is a photo of the TKB-0116 assault rifle, created by Igor Yakovlevich in the late 1970s for the "Modern" contest, the one in which the future AKS-74U won.
   The Stechkin assault rifle was distinguished by the fact that it had an action scheme atypical for this class of weapons using the recoil energy of the barrel during its short stroke, and locking by turning the same barrel.
