AR15 Feed problems

[mfmayes49]

I have a Cal legal AR15 with removable magazine. Im having feed problems with 10 round mags i bought at a gun shop. The problem is it doesnt feed the final round. THe bolt stays back as if it was empty and the bullet just sits in the chamber. The rifle is new, is it the mag or rifle? Does rifle need breaking in?

I have no gun shop to take it to have checked. One i dont trust and other wont even look at a oll rifle.

thanks

It's not the rifle, it's the mag... I have had the same problem with some of my 30 Round Mags.. Where the last round will not feed.... No biggie, Try to get some Bushmaster 10 round mags...

If it's a Cproducts 10rd mag, try cutting the springs by removing three rings on the floor plate side. The spring is just too stiff for such a small mag. Over 1000 rds after cutting the spring and never had the FTF on the last round anymore.
