I was out shooting my stag model1 today got about 10 rounds into the mag go to fire and nothing. I try to put the rifle on safe it wont go, try to clear the round charging handle stuck and the bolt is almost closed. How do I clear this? Do I break the gun down? Gunsmith? Any help is apreciated. The round was federal.
 
You probably have a bent or out of round bullet. I have have that happen a few times with a buddies DDM4. PROCEED AT YOUR OWN RISK!! The way I have cleared them is by putting the butt stock on something hard, barrel straight up. Keep you head/face/fingers/cats/dogs/etc away from the muzzle. I put downward pressure on the non latch side of the charging handle with my left thumb, and use the bottom of a mag to hit the charging handle down swiftly on the charging handle latch. So far is has worked every time. I would also not recommend doing this indoors, either. Good luck, RMV.
 
The method described above is a good way to break a charging handle. Most use the mortaring method when a round gets jammed in the chamber.

Collapse the stock, keep your finger off of the trigger, with the rifle in a vertical position, strike the stock on a firm surface while putting some downward pressure on the charging handle. Use some sense when striking the butt on the surface. It usually doesn't take much. The idea is to get the weight of the bolt working for you.
 
Sounds like the hammer fell on the stuck round and since it's not cocked the safety won't go on (normal).

Did the last fired case eject???
 
Pop out both pins to remove the upper from the lower. You can now look at the stoppage from the bottom of the upper and get a better idea of what you have to deal with.

This is the correct procedure for clearing a jammed round that locks the bolt partially open. Don't slam the butt down like you are splitting wood. A little tap generally clears it.
 
Tonyangle and madcratebuilder are correct. My limited experience with this problem this is how i have fixed it. This procedure has been taught at a couple of classes i have taken.
 
I did hit the forward assist and nothing happened. I am unsure if the round ejected. I tried the hit the but stock on the ground but it didnt work should I try lubing it then hitting it on the ground.
 
You could have a primer blow out and go over the top of the bolt carrier - that can cause a good lockup - I would mortar it first and then disassemble next to assess the issue.

Penetrating oil such as Kroil does great add it so it seeps in around case.

Were you using commercial or reloads, dirty chamber will also cause them to stick especially if using steel case ammo coated in wax, but oil is your friend in this situation.
 
Ok thanks wing man ill try that later today. I was using a mix of lake city and federal ar223 so commercial. I am fairly new to the AR platform as you guys im sure can tell. Will it break down with the bcg stuck about 90% forward and a round chambered?

If it didn't work, stroke it a bit harder. Some of those can really be stuck in there pretty good.
 
Your AR should be able to run dry...if an AR WON'T run dry there is something wrong with it.

Mortar it harder on the ground....a good 12" high drop with some force should pop it right out.
 
Has the same thing happen to me on my doublestar ar. I was shooting reloaded ammo at the time and apparently one of the cases had not resized properly. Jammed everything tight. Luckily one of my buddies had a lot more experience than I, mortared it just as described, popped right out.

The only way to break it down is by pulling the back take down pin and front pivot pin. Then slide the upper forward a bit.

In all due respect no machine( and the AR is a machine) should run dry, while it may do so short term in the long term it will fail / wear and break, clean and lube any automatic firearm insures long term use.
 
I use a 50/50 mix of ATF and 30wt non-detergent dino oil on BCG's. I like to soak em and let them drip dry before reassy.
I think Remoil may be a little light for that particular set of components but as long as it's wet, it should run. I still doubt lubrication is the issue here.

I use atf:stp oil treatment in about a 60:40 ratio. The ATF is great for wear protection and dirt lifting. The STP thickens it up so it sticks better.

It happened to me too

Had the exact thing happen to me a few weeks ago. I collapsed the stock and put pressure on the charging handle and bounced the butt straight down on the bench. The weight of the BCG and the additional pressure on the charging handle freed the unfired round. On inspection of the round I found that the case mouth was crushed on one side. Not sure what caused it. :confused:

I lubed the BCG and charging handle, ran a brush through the barrel and chamber then tried again. Didn't have any other issues for the rest of the day. Contrary to what I've seen some say on this thread, ARs want to be run well lubed. If you run them dry, they jam.
 
Thanks guys got it first try this morning! I think what i did wrong was I wasnt pulling on the charging handle. Thanks for all the advice and I will be using atf from now on to lube my bcg. The round i pulled out was live and scratched and rough around the crimp.
