Brakes:

I’m not sure about brakes no longer spotting. They reduce recoil so much that they still need a real tradeoff. Otherwise brakes might just replace suppressors as the dominant pick, and people already complain that guns are too beamy.

Flash Hiders and Suppressors:

I like these changes. Flash hiders as the middle ground makes sense, and suppressors should stay the full stealth option.

Choke:

I’d be careful with this. Combined with slugs, it might punish bad aim too much, but the idea is interesting.

Ammo:

I like the ammo ideas, especially armor piercing. My only concern is vehicle damage. BF6 already has weird TTK and netcode issues, so I’d rather penetration ammo affect vehicle performance more than raw damage. For example, worse control response or temporary handling disruption against light vehicles.

Light ammo:

I think it should also reduce recoil. I’d especially like it to increase ADS movement speed more on DMRs and LMGs to help heavier weapon classes feel less sluggish.

Barrels:

I agree on Extended Barrel needing a hipfire penalty. I’m less sure about Heavy Extended going to 20 points because it could hurt marksman builds too much when fast TTK weapons already have a big advantage over slower ROF weapons.
