M-LBE Leg Rig with Pistol Mag pouch - can't add ammo by clicking on empty slot in merc inventory

Strizh Spetsnaz - autofire is messed up - the rate of fire is too slow, and the wrong sound is played

CZ 700 Sniper - can fit foregrip

HK53A3 takes ordinary suppressor and TI (but weapon is 5.56 calibre)

Beowolf rifle scope mount - for Battle scope 4.0x is grayed out but you can still attach it by clicking on the slot

The Bizon TacStock can accept a foregrip, this doesn't seem logical

The PPK-12 graphic is not centered, but a bit to the right

L85A2 LSW - integral foregrip on back end of rifle.
I know that such a attachment is possible but I can't see how it's supposed to work. How to hold a bullpup rifle like that, and have better autofire accuracy?

AK Bullpup kit and Tacticool Stock - doesn't highlight compatible weapons in Inventory

Tacticool FN stock - not sure but I think I was abble to attach it on some guns wich weren't FN Minimi

Rate reducer - can attach to some non AR-15 guns (FN F2000 Tactical, L85A2 LSW...)
- is this intended?

9mm Drum adapter doesn't reduce reliability like other drum adapters

MP5/40A3 and some other .40 S&W cal. weapons have a positive lodness modifer. .40 S&W ammo has negative loudnes modifier. Is this intended or a bug?

+P+ 9mm ammo - 6,6,15 and 30 round mags don't display the damage bonus in UDB
(the bonus is applied to the weapon but UDB of ammo item doesn't dislplay in advanced tab)

D5 - should have shooting range facility

Drake - too many empty containers (closets, crates etc...)

You could add camo to pants (armored)

I suggest changing the short names of guns with Tacticool stock upgrades.
For example, a regular "Bizon" and a "Tacticool Bizon" with tactical stock will be sorted far apart on the sector inventory screen so they are hard to find. I think that it would be more practical that the naming convention for short name is for example "Bizon" and "Bizon Tac" for the regular and upgraded weapon.

Throwing knives should fit in knife slot, and knife pouches

Tripwire should be smaller size

Titanium plates - shold hava a lower AP penalty and smaller armor rating to distinguish it from the Steel plate

Lasers - This may be personal taste but I don't like Stealth modifier penalties on the lasers. Reducing camo to simulate a merc being more visible due to using a laser, seems ok. But I can't gat past the fact that a laser reduces your chance of being quiet.

Molotovs - can you make them? If yes, OK, if not I would like them to be included in your mod

Berreta Storm MX4 a bit too powerfull for my taste. It is a newer bullup design, but it's accuracy and AP cost are too good in comparison to other SMGs

Styer AUG Para - also too powerfull (a bit too high accuracy)
- also, it should have an integral foregrip not a slot for one

MP5 variants - these seem a bit weak on par with other SMG you can gat at this coolness. I would like to see higher accuracy for these guns (after all they are reffered to as very accurate SMGs in the real world). Maybe you could make them a bit more powerfull, but increase ther coolnes

Desert Eagle .357 - damage is too low

Aimpoint projectror - why does it have Aim Cap penalty -16%? It should have -10% if it were a scope but it's not. It's a reflex and laser combo, but it has no magnification, so why the Aim Cap penalty?
Also:
- too high laser penalty (Korsak has 2.0x laser projection and has penalties of only -5%)
- why does it have nigh vision bonus?

1PN58 and M3 Snooper scope - too high night range vision bonus IMHO. Since enemies can't use them I think this bonus is too high

AR-15 1.5x scope has Aim cap modifier of -17%. Shouldn't it be -10%, as on a regular 1.5x scope?

Dual mode sight - in CQB mode has Aim Cap Mod +10. Is this on purpose? Shouldn't it be -10% as any 1.5x scope
- in 4.0x mode the tunel vision is 25% (for a 4.0x it should be 40%)
- also the AP modifier is -5% but I supposse this is intended, as it's a collominating sight as well, so it's faster to aim

Muzzle breaks - AP reduction is a too powerfull bonus, and doesn't make sense. Why would a muzzle break decrease the time needed to aim?
Also:
- shouldn't fit on pistols
- AK muzzle breaks should fit only on AK rifles
For example AKS-74U can fit both the Muzzle Break and the AK Muzzle Break (should fit only the AK variant)
AEK-971 can only fit the ordinary one, while not the AK variant (should be other way around)

I would remove the ability of pistols to mount a flash hider.
I know it's like this in the original 1.13 but I can't see how it's possible without some kind of special barrel replacement/extension? For game balance reasons as well - I see the pistol as a fast backup weapon, but it can give out your possition unless using a supressor.

Bullpup guns should not be able to take a drum adapter. In real life, it would be very difficult to aim and shot using such a magazine.
AK Bullpup Kit - should disable the use of the same

AK grip fits on Saiga. Not sure if this is possible. Either way, the AK grip is for autofire weapons, so it doesn't seem logical. The grip does reduce AP costs, but I would still not allow it on a Saiga since you can already make the Saiga a fast and very powerfull weapon by using the Kobra-Korsak combo

SVD and some other guns only accept 9x version of 1P Minuta. Same with DM sight. I assume it's this way, since you would have to make a new available attachmet slot for each mode these varying scopes have.
The fact that a multi-mode scope can fit to a weapon only in a certain mode is not a problem once you know how the in-game system works. But it's hard to figure it out for a newcommer. A recommend adding a few lines in the descriptions of the multi-mode scopes which would instruct the player on how to use/attach the sight.

+P+ Ammo description should also include PP-2000 as it has high reliability

Garotte item description - should explain it's a James bond style watch-concealed weapon

HMX - should be more stable then TNT but it's not, both have volitality 2

Bloody Knife - Maybe add a item transformation to clean the knife
