Bolt Malfunction

Recommended Posts

Good afternoon everyone, I have a Talon AR 15 and it is a DREAM to fire, until yesterday. I was at the range and fired my first 9 rounds without a hitch and then the bolt failed to charge. I cleared the weapon and changed the magazine and got the same results. I changed the ammo and same thing happened. I field stripped the weapon and roded the barrel, stripped the bolt down and cleaned it, lubed everything up like it was a stripper on Saturday night and still got the bolt malfunction. I am thinking that it may be a blockage in the gas tube. Can anyone offer any assistance?

Did the gas block move?

As Gregg suggested, check your gas block. What you're describing is almost always a gas issue.

Remove upper from lower

Remove bcg and ch from upper

Perfectly plug barrel within upper

Place finger tip near end of gas tube within upper

Blow hard through muzzle end 

Decent flow out the tube end?

Place finger tightly over gas tube end within upper

Blow hard from muzzle

If any air escapes, you have a leak.

 

If a leak is detected, we'll proceed from there.

 

Enough of a leak (escaping of gas) can cause the bcg to not cycle properly

  x 2. No airflow your gas block is not aligned properly.

I think this was a drive by. Four days and no show.

Nope, not a drive by. Just returned from my 23 Y/O promotion ceremony to E6/Ssgt. She is a combat medic in the Army. I appreciate all of the suggestions and will let everyone know what the solution turned out to be.

 

But no drive by....

Congratulations to the daughter. Fantastic achievement.  Anything of that magnitude certainly trumps being here!!

 

Keep us in the loop as you whip this one into line.

E-6 medic at 23! Must be very sharp. Congrats to her. Where is she currently assigned?

That's fantastic!  I have a nephew that's a combat medic in the Army, stationed at Fort Campbell in KY.  My daughter is a Logistics Readiness Officer in Okinawa.  Tell her thanks for her service!

And yes, please let us know what you find.

Good afternoon everyone, I am happy to say that the issue has been resolved.

FUNNY story Actually.

I was disassembling the AR and trying to cover all of the items that you all responded with when my wife, a weapon Novice, picked up the stripped down upper assembly and said "Hey is this suppose to move like this?".

She brought to my attention that the gas tube and the gas block was slightly shifting, something that I know that I visually checked several times before. After careful examination I noticed the issue. The gas port outlet of the Gas Block was not aligned with the gas port inlet of the barrel. I aligned both ports and secure the gas block. 

I took it immediately to the range and *** TA DAAAAHHHH***, issue resolved. The weapon performed Flawlessly.

 

Sometimes it takes a second pair of eyes to notice the Obvious. 

 

BTW, my youngest brother purchased the exact same weapon and was having issues with his rounds improperly feeding of double feeding. I applied the same resolution to his weapon and went back to the range the next day and it functioned flawlessly as well.

 

Lesson Learned:

Proper gas flow is essential and should be the first trouble shooting option:

 

Thank you all AGAIN for the much needed and appreciated feed back.
