The pack doesn't seem to conflict with NEkram's pack, which I guess is a good thing if you really want both packs at once...and considering both packs are around 430 datablocks in total, that wouldn't be such a great idea...
Anyways, I really like the ADS especially for the rifles. The bullets for the the weapons especially for the sniper rifles are also a great touch.
EDIT: Your pack is ~197 datablocks iirc, so it isn't too bad for a relatively large weapon pack. NEkram's is ~230ish iirc, just in case you thought yours was 430 datablocks, lol.
Also another note: you misspelled your username in the credits section, but it's not like it's a major issue anyways...
