Please help me!

your english is not bad. if u can controll the ak47 than just get ak knife. if u are a sprayer, get m4 crystal, i have it too. but if i am you. ill get D.E. gold. its so sexy ,for me. m4 crystal is just like m4 silver.

I'd say the AK47-Knife.

This is just my opinion.
Deagle looks bad. 80 coupons is way too much.
Crystal looks bad. 80 coupons is way tooooo much. Same stats as the silver/adv but with less ammo...30/90.

Some people say the M4-Crystal has less recoil, but honestly what difference does it make when the silver/adv have low recoil already right?

crystal... there is a reason it has less bullets 35/105 would of made it too sexy rated R and it's so accurate you'd get even more kills and get kiked for hacking.

The only thing useful is M4-custom or Golden deagle. Again as I repeat in another post, The ak-knife has the most recoil, weird spray patten in the ak-family. The ak's are actually slightly different if you use them, but not a very big difference.

ak knife is good for single shotting plus a knife. ( do not spray with this gun unless the enemy is close)

m4 crystal has lower recoil in my opinion.

Golden deagle has 10 rounds per mag. its useful that way.
