PROBLEM SOLVE!

The follower of the PMAG cause me a lot of trouble and since I change it the gun run flawlesly...Because the folower he's too short the butt of the ammo goes down and the bolt pass above. That cause FTF...

Did you checked the little spring under the extractor? Is this spring ok ?

Did you checked your AR15 with someone else bolt?

I think in the worst case scenario, you'll have to change extractor, extractor spring and or mag.....

Hi Folks!

I bought a Core15 based model and I realy got some serious trouble with.
Lot of FTF and FTE. The pmag that came with the rifle seems realy crapy. If i bang the mag too hard in the rifle the munition take an bad angle. They nose goes up and the bottom goes down so the bolt cant push de munition in the chamber.

The rifle have trouble to eject the hot brass and when He doing it the brass just slowly fly 4 feet away.

Any tips will be appreciate. TY

do you have another mag?

first thing i would do is get another magazine and try it again, i would also suggest that you run the rifle wet for a few hundred rounds to work it in a bit...

1. Make sure the rifle is well lubricated.
2. Try several other magazines.
3. New firearms usually have a "break in" period.
4. What ammunition are you using?

If you're trying a new rifle that is too dry with a single possibly bad magazine shooting MFS .223, it's likely not the rifle, but something else.

try a new mag.

Make sure the castle nut on the buffer tube is tight , if its loose you will have all kinds of problems.

I need advise please !

1-16” 4140 Chrome Moly M4 Profile Chrome Lined Barrel 1:7 Twist
Chambered in .223/5.56 x 45 mm NATO[/I]

DOes that mean the barrel he's 556? ( I supposed but want to be sure)

2- If he's not 5.56,it is true that I will need to trim my military brass?

3- A brass with primer crimped does that mean its a military one for sure?

4- If I have both civ and mil brass, if I put the same amount of powder does it will be a serious issues ?

Thank you for your help!

the core-15 is good to go with 5.56
