Hi everyone,
I'm new to the forum, kind of new to AR's. Shot them a bunch over the years, but finally bought my first. I went with the Core 15 M4 Scout, good price and everything I've researched a good rifle. So I shot it for the first time today, it has great grouping, but occasionally I would get a 2-3 round burst. I thought possibly a bump fire at first, Then my brother and nephew also shot, wondering if it might be something more. Trigger issues? I was using all .223 ammo, some Federal, Winchester, and PMC. Thanks in advance for the advice! |

Thanks in advance for the advice! Did you shoot any 5.56, or military ammo? Could be the firing pin is hitting and igniting the softer primers Check to see if the trigger group shows any damage |

If this is a factory built rifle that you haven't messed with the internals, then I would suggest contacting CORE Rifles (Core15), as they are an Industry Partner here. Core Rifles.

The only time I ever had a new rifle double was an AK I bought on the eave of the "1994" ban and I spayed WD-40 all over the internals and placed it in my safe. A decade later I went to shoot it for the first time and it doubled.
I couldn't figure out what could be wrong until I recalled how I stored it. Simply spraying a bunch of Gun Scrubber or Carb cleaner and the judicious use of a tooth brush fixed the problem. Try cleaning the crap out of the trigger group first. Follow with light oil on all the contact points. If that doesn't work the disconnector spring is probably installed upside down. |

Ditto on a disco problem, but on a new rifle, have the manufacturer resolve the problem!!!!!
Could be a simple as just the disco binding, on more complex as the disco being out of tune, but unless people with these problems send the rifle back (have Core send you a shipping label so they pick up the shipping cost on their own dime), then the manufacturer has no way of knowing that they have a QC problem with rifles going out the door with problems instead. Bluntly put, if the manufacturer is having to eat enough shipping costs, and them shop times to double check the rifle and correct them after they come back in, then they have nothing to prod them to make sure that they are going out the door correctly the first time instead (see Hesse rifles, and why it demise). Figure with shipping cost both ways and then shop/paper work time to repair the rifle to get it right, they are eating at least $100 every time a rife comes back for repair that went out wrong. Enough of these, and they will figure it real quick that is cheaper to just hire someone on to Q/C the builds and test fire it for a few rounds before it leaves the factory to make sure it correct front the start instead. |
