The inclusion of this next piece in this post was nearly prevented by Telegram's retarded feature of not allowing you to copy and paste images and I couldn't be assed to use the snipping tool to extract it from a screenshot so I shall provide a link instead
Bullpup PSL owned by some Russian guy, differs vastly in construction compared to Idlibi examples
An image of a new, unnamed AK-12 variant has surfaced. Based on it's characteristics its most common analogue would be an AKS-74u, the gun features a metal M-lok rail and all the other features of an Obr. 2023 model AK-12. This is most certainly NOT an AK-12SPK as it had a 6 slot handguard and as far as I can tell never actually went into production.
Another new Russian firearm, the PKZ, the PKM Bullpup conversion of olde rejuvinated into a factory produced firearm featuring M-lok. Now if only the Russian MIC could actually design and produce a 5.45 LMG so that it too could be bullpupped
Dutch Pattern Sudanese AR-10 being used by an RSF rebel during the current hostilities in Sudan, one was spotted a few years ago being employed by a Houthi fighter in Yemen.
30 FGC-9 MK.II's seized from rebels in Myanmar, this would be as far as I know, the largest single seizure of FGC-9's in history
Zenitco "Leader" Kit on an AK-74M, has a stepped down section of rail near to the front sight to allow IR Lasers to be closer to the bore, a screw on handstop to partially cover the handguard retainer (that also might increase rigidity of the rail but idk not an engineer) and has their proprietary "Basis" rail all around including the 12' o'clock position unlike the Sport-4 kit which has pic rail. The B-33 dust cover also has two arms that mount to the rail accounting for half of it's mounting points
Soviet designed machineguns cobbled together in America sent to Ukraine to Fight Russians.
You WILL be detected by either Infared or Thermal signature
You WILL be eliminated with subsonic 9x39 by a leaf suit wearing bushman.

Those of you who know of the work of the Sumy DRG know that guys wearing leaf suits AND Heavy PC's with cockflaps can reap a bloody toll with Suppressed AK's and PKM's.
In the 6 year period of 2017-2023 Texas ATF seized nearly 1000 glock switches, 500 of which were recovered in 2023 itself
I have discovered a company, Black Steel USA, that makes a series of relatively easy to install folding gas pedal style grip aid devices for a variety of popular handguns, there has been a continuing and in some regards accelerating trend of incorporating technology and features from the Competitive shooting world into the defensive handgun world the most prominent being the MRDS and to a lesser extent compensators and most recently thumb ledge or gas pedal style devices (Tactical Development, Icarus Precision, QVO Tactical all have either some form of offering)
Issac Botkin, Brother (not Father as he is commonly mistaken for) of the ever controversial Lucas Botkin has put out a video musing over the future of the "Duty" Handgun, even going so far as to create a high quality (for the few hours he spent making it) 3D Model of a concept gun that incorporates several already existing features into an amalgamation of theoretical performance. I would highly recommend watching it, wonderfully done video. The only thing that I could think of to improve his design would be a folding gas pedal like those detailed above.
