Angled grips only get added to the Eagle Heavy/SCAR-H and Contractor Rifle/TTI TR1 by default.

If you have Custom Attachments for Custom Weapons, some custom weapon may have these angled grips (only if the creator has explicitly enabled angled grips on their custom weapon).

@rjc9000 thanks yoi I found the problem, I forgot to add [value_node value="wpn_fps_ass_m4"/>] near the [<value_node value="wpn_fps_ass_scar"/>].

If you don't mind doing a bit of work, you can re-add your desired weapons to the list of attachments.
Open up the main.xml with any document/text editor such as Microsoft Word, Notepad, etc.

Every attachment will have two lines of code:
<weapons>
(lines of code)
</weapons>

To add the CAR4 to the list of weapons, insert <value_node value="wpn_fps_ass_m4"/> between every <weapons></weapons>. It should look something like the following:

Repeat process as needed.

If you want to add other weapons, such as the AMR16, you would follow the same process of adding <value_node value="weapon_id_here"/> code.
For example, the AMR16's internal name would be "wpn_fps_ass_m16", so you would add <value_node value="wpn_fps_ass_m16"/> between every <weapons></weapons>.

@RJC9000
will try it out. thanks a lot!

@RJC9000 Can that be added to an update? To work with more weapons of the game?

That is correct, this mod pack does not override existing weapon animations with vertical grip hold animations.

This mod pack explicitly only adds vertical grip attachments to weapons that already use a vertical grip hold animation, such as the F2000 (Union), UMP (Jackal), or CZ805 (CR805).

Just for vanilla and/or select modded guns that use vertical grips by default (F2000, UMP, etc).

Getting non vertical grip vanilla guns like the M16 or AS Val to use and hold vertical grips would effectively require overriding the vanilla weapon's hold animations to a different weapon's stances (like overriding the M16 to use the HK416C hold anims or overriding the AS Val's with the RPK hold anims).

Exclusive attachment to my MW2019 SCAR-H.

Yes, it's Blackbeard's Rifle shield straight from Siege.
Sadly, the attachment is purely cosmetic and confers no damage reduction. I did try to apply Killerwolf's Gunshield code, but the only part that I got to work was the Gunshield movement speed penalty, not the damage reduction.

If you want rifle shields for most weapons, use Killerwolf's Rifle shields.

Blackbeard's shield is not included in KW's pack, since my Nerfbeard shield was made a long time after KW's pack. I did offer KW to add Blackbeard's shield to his Gunshields.

@RJC9000 Aw :< would love to use your mod but i just cant move away from Irenfist mod and it does not support your mod so :<

If you're looking to making setups using only MW2022 parts, the below link has a weapon with exclusively MW2022 M4 parts.
https://modworkshop.net/mod/39744

It lacks vertical grip support (long story) and instead uses Fnuxray's M4 anims. I didnt release said weapon when MW2022 launched because I'm trying not to flood MWS with any more AR15 derivatives than I already have.
(Do I blame COD for making the AR15 consistently good in every appearance it makes in a COD title?)
