21 in 9x21 means that cartridge is bigger (because of bullet or case). So 9x21 silencer can pass 9x19 bullets, can be installed to 9mm barrel. It may be some difference in efficiency, but whateve.

Fixed

Fixed for Mk17

As no futher discussion happened - closing ticket.
Optics vs NVG may be fixed in https://dev.cup-arma3.org/T3201

Vanilla magazine classes are: "150Rnd_762x51_Box" and "150Rnd_762x51_Box_Tracer"
Both included to CBA's CBA_762x51_LINKS magazine well.

@Goopy Please, move SA-58 to separate ticket and leave this one for M4/M16 only. Thanks in advance!

Not saying that everything is ok with recoil, but SR-3 is pretty light (2.4kg with loaded 30rnd mag) and fires heavy bullets (16 g SP-5 vs 6...12 g 7.62x39 variants). So recoil should be noticible.

Side attachments for AR 15 rifles are available for purpose. If some specific attachement or specific rifle has issues - please create new ticket and specify weapon and attachement classes in it.

currently possible to attach rail accessories to these rifles

Yes

it also says it matches vanilla values.

Not excatly, it says:

According to some internet data MDZ ammo may be used in belts in format API-T-AP-API-T-MDZ and used more for indication purpose (as it makes visible flash on hit). For ZPU there are MDZ-T-MDZ belts.

Fixed for Mk 16

• This is, in my opinion, the biggest issue, but all of the guns seem to fire WAY too slowly. The real XM8 and Arma 2’s XM8 rifles fire 750 rounds per minute; these ones fire something close to 500 at most.

Fixed

All M14

Brief search makes me think that M14 has no fast attachable suppressors and it's required to change whole flash suppressor/front sight part (it's single detail). As for me - it's fantastic to be able to do this operation on battlefield. Guess we need extra model with non-standard flash suppressor which allows to attach joint 7.62 muzzle devices.

Looks like this caused by magazines[] array that have duplicates.

Actually i can't find any reliable info about NATO subsonic rounds in 5.56/7.62. Only .300BLK.
Feel free to share info/links if you have.

Display name changed to M4A1 (Grip)

Replaced BURST to AUTO mode + textures fixed.

Fixed texture for handguard, receiver and buttstock ring.

Fixed muzzle velocity for CUP_arifle_M4A3_black, CUP_arifle_mk18_black, 'CUP_arifle_SBR_black'

Just set ACE_laserpointer entry in CfgWeapons class of your side attachment
ACE_laserpointer = 1; red visible laser
ACE_laserpointer = 2; green visible laser

Please, mark 'holes' at screenshot, i can't find any except designed to be there :D

All pistols with rails now using joint side rail.

V mark now allow to aim from 300 (7.62) to 400m (5.45).
9x39 allows to hit at 200m if V mark placed on top of target

Please, verify on new build.

Switched to default value (1000m)

Fixed for M249 (long barrel) ballistics

Fixed for M16A4 ballistics

Foregrip is too far to make handAnim to look normal in prone position and there is now way to change handAnim mid-game. Moving ticket to whishlist, maybe some day arma will be able to handle handAnim switch
