So I finally mastered a gun in the game. I got the Scar completed I'm around level 67-68 1st prestige. It took forever to get for the Bullet Penetration kills. I may have put everything off yesterday when I had my last day of vacation from the holiday/birthday and not accomplished anything I should have lol. Now on the to the Barret ha.
What gun did you guys finish first or are close to? Did anyone have as much trouble with the penetration part as I did???

i didnt have anyone problem with the penetration part thats what she said.

haha JK but the FMJ kills always take the longest on every gun. prolly cause i dont try to shoot through walls on purpose.

first gun i did the mastery for was either the FAMAS or the ACR or the TAR

OH snap....a penetration joke ha.
I tried to do the deal with the heartbeat sensor....but's pretty useless on TDM averyone runs around faster then the HB sensor can track them. Although I do believe if you are on highrise where the helicopter is, the fencing on the edge of it will count for that if you shoot through there.

I've got Mastery on all the AR's and the UMP. Tried for other SMG's but the FMJ kills take too long.

so far, ive gotten it for m4a1 and the scar, but im gonna try to get it for all guns, and i'm not even close lol.

Got it for the m4 and m16 . Although I have far more more headshots for the SCAR and ACR.

play hardcore for easier FMJ mastery. Kills are much easier through the walls with decreased damage on.
So far i've mastered all AR's and Subs. Only about 20 FMJ off completing the Barrett.
then i'lll start the LMGs

i found the toughest sub to master was defo the Vector. Glad thats done now.

embarrassingly enough i used the HB sensor on the ACR when i was going for nukes. helped a lot since most kids dont use ninja. my little mini UAV

The first gun I mastered was the barret as it's the only gun I used without a silencer back in the day lol

Probably the hardest gun to get bullet penetrations kills with was the vector...

I'm havin no problem with the fmj part on the 50, you just go on wasteland and look down the the under room where you can look to see the entrance from the other side and shoot through the thin wood wall in there.

i've mastered all AR's, SMG's and LMG's except m240(get it back soon). of the ar's the fal was the quickest to complete then the burst weapons. smg took the longest, vector was ridiculous. LMG's are easy i usually finish the challenge in about 250 kills. first one i mastered was either acr or m4

I haven't done any challenges, I'm going after the scar mastery tonight, I covered a lot of ground within an hour.

wow its ind of easy to get the 40 penetration kills if u dont try lol
just have FMJ on ur weapon and just have fun.....sooner or later u will get the 40

i have mastery for Famas and Scar-H

XBL: UnsoundMrBlaze

Ahh ur like me... I've mastered every gun except ext mags on the WA2000 and L86 lsw. The vector was stupidly difficult to do, I agree. I got red tiger on it before I completed FMJ kills lol

I like terminal/scrapyard for fmj kills. I should find mastery on the AK easy as i love that gun , but I'll be damned if I can use the ak with acog .....what a waste of time.

I'm Just happy the amount of acog scope kills needed is relatively small.

well throughout my 8 times prestiging, I've unlocked everything for the intervention 5-6 times! Ditto for the 50.cal. As for the rest of the guns, I really dont attempt to unlock everything to get the gun mastery challenge, Ive decided to get to 10th and then work on doing all that stuff then. Therefore gives me something to do when I'm not prestiging anymore. But I have done it for the TAR, and Scar, without really realizing it tbh D;

Never done it, but im getting close with the FAMAS. 15 more Bullet Penetration kills! But yeah, I usually just play, and I'll get maybe one or two per match. And someone said this above me, but shooting through a fence does infact count towards the FMJ kills.

Mastered guns: Scar-H, RPD, AK47.

Easiest was the RPD. The two AR took about an entire day to get each, but the RPD was about 2 to 3 hours.

Im trying to master FAL but I cant make any perfuration kill even with FMJ, I already tryed headshots, executions, with or whithout scopes, and even with SHOTGUN!!!
Im portuguese so I dont realy understand how to make a perfuration kill

I've mastered the M4, SCAR, M16, Tar-21, ACR, FAL, UMP45, RPD, M240, MG4, Barret, Intervention, and M21. Its starting to suck though because im gettign to guns now that i hate using- like the FAMAS and L86

the first gun i mastered was the scar because of the power. and after i saw the little golden title saying scar, i wanted more. now ive mastered every gun using the same technique. its long and annoying but it works on most except smgs that was 2times as long.
once you unlock everything except extended mags bling the gun with hbs and go to HCHQ people camp all the time without ninja so just spray through the wal, cheap but efficient even the barret and intervention worked that way. but as smgs dnt have HBS i thought more firepower through the walls and blinged it with akimbo, just see someone, hide behind something and SPRAY! i know it sounds awful and cheap, but it worked and i have mastered EVERY gun, my last to do was the M240 because of how much i hate it that i could never last 300kills to fmj.
