kitty kat ar pistol issues

[cofi]

Just bought my first ar pistol!!!! was playing around with it on (cheap tula ammo)and had some problems with FTExtract and im thinking this thing is a bit under gassed is there anything i should try to play around with before having the gas ports opened up??? and if not what size should i poen them up to???

Try brass ammo first. Then diagnose issue. Tula is steel, steel ammo is not always great.

I would strongly advise against opening up the gas port. Like Del said-dont shoot steel cased ammo in an AR. Brass casings will expand to the chamber and then shrink a touch, steel casings expand and are not as elastic. You will stick a case eventually.
Put at least 3-400 rounds through it before you pass any judgment on its reliability.
They are also a bit sensitive to your technique, make sure you are not "limp wristing" it.
Is this a factory complete pistol or a build? If it is factory whose is it?

factory dpms.......there is no way i wont shoot steel case if a gun doesnt shoot steel but will function with brass then it is barely working with brass imo..... all my other ar's only get a diet of steel

po put 100 rounds through it ive got like another 200 or so ill try shooting it some more but do you have any buffer weight/ spring combos i can try?\
why not open up the gas port???

its your AR, get out the uni-bit and open'r up.

My SBR has a Kitty kat 7 1/2in upper on it and it works great the way I got it, but I dont shoot steel case ammo out of it.

+1 on steel case ammo junking up an otherwise perfect gun. Many years ago I had an AR that always gave me extraction/ejection/cycling issues. Turns out when I quit trying to run the steel case stuff all of my problems magically disappeared. Needless to say, I now reserve the steel stuff to use in AK rifles.

But, do what you wish as it is your weapon. Over-gassing an AR by making the gas port too large will cause issues as well. If the chamber isn't chrome lined i would recommend doing some serious polishing of the chamber to start with and see if that helps.
