Was in a hurry putting my MPX back together after cleaning and put the bolt carrier group into the upper receiver backwards. Pushed on it and heard it click. Realized it when trying to join upper and lower receiver. I know, dumb as he.. and not paying attention. Now bolt carrier group is jammed in upper receiver. Any idea how to remove. Don't be to hard on me guys. I have taken it apart and put together dozens of times. Today, I screwed up big time. HELP !!

I would try a long wooden dowel and hammer, light taps, and see if it budges. Try working the dowel all the way around, so that if moving it comes out fairly even, if possible.

All I can think of, and don't even know if it's possible? Got any pics?

gehlsurf: After placing the charging handle in the upper receiver, I placed the entire bolt carrier group with the two spring rods into the charging handle groove. Not paying attention and gave it a good shove with the palm of my hand. Still did not pay any attention until I tried to join upper and lower receiver. Obviously, no go..then realized my screw-up. The charging handle will release, but does not engage the bolt carrier group. Wonder if the bolt group is not even sitting in the groove. Did hear a click though when I pushed on the bolt. Will remove the barrel to give me a clear shot at placing a dowel on the edges of the bolt. If that doesn't work, will take it over to the gunsmith at Shooters World on Fletcher Ave. in Tampa.

Thank you for your suggestions. I still can't believe I did something so darn careless. Your post is appreciated.

I didn't realize you live in Tampa, I'm in St Pete!! Have you had any luck with the gunsmith at Shooters World? I have a gun smith here in St Pete, guy cerakote and installed my binary trigger in my MCX, and built my integrally suppressed shotty, dudes a genius. If you feel unsure about shooters world, give him a call.

Don't worry, he's told me crazier stuff people have done on accident, these things happen more than you think.

Oh, be sure to put a towel or piece of wood under the upper when banging with the dowel, proabably common sense, but you don't want to be scarring it on concrete or the sort. Also, will pad the taps, remember, aluminum is soft.

gehlsurf: Live north of the Univ. of South Fl. Have used the gunsmith once for some bore sighting on my AR-15 when I mounted a new red dot. Did a good job on that. Have heard many positive comments from other shooters at the range regarding the gunsmiths. Going to remove the barrel as I mentioned and Icarlos also suggested. Going to give it a try using a dowel and some light taps. Keeping my fingers crossed it will dislodge and I will avoid taking it to the gunny.
Thanks for the tip of Colts Ballistic Logistics. Going to add his name and number to my contact list.
I know that I am probably being a little hard on myself, but I have been around weapons all my life (civilian/military) and I can't even comprehend what I was thinking when I did it. Correction: I wasn't thinking. Again, appreciate all your insight and suggestions.

What about removing the barrel and taking the pressure off the bolt carrier group?
Icarlos: Am going to remove the barrel as you suggested. It will allow me a straight shot with the dowel. Hoping some light taps around the perimeter of the bolt will dislodge it. Not hearing from any other members, so have to assume that taping with a dowel stick or some other blunt instrument is the way to dislodge the jammed bolt carrier. Thank you for your post. It is appreciated.

sigmpx2017: Good examples of jobs best left to a professional. As you state, this may very well be one to add to the list. Going to try the dowel stick and some light tapping, but if it does not release, your advice is well taken. Appreciate your post in trying to help me.

I'll suggest removing the upper, handguard and barrel - and then a very close/careful inspection - before deploying your hammer & dowel.

You really need to understand what that 'click' was about. This may be a clue that some components are potentially locked together and could break if force is applied.

I don't own MPX, but my MCX Carriage Assembly looks very similar. If I insert the Carriage Assembly into the upper backwards, and move CA forward until the action rod is flush with the upper's rear - the Carriage Assembly's recoil rods rear spring plate is hanging out the front of the upper.

I'm guessing that the 'click' you heard was this polymer spring plate snapping past the front of the upper receiver. If this is what's happened, simply re-aligning the spring plate with the upper should let you slide the carriage assembly out - without forcing the issue with a hammer...

Cheers

Kansascity45: Your diagnosis was right on. Did some tapping using a dowel and nothing moved. Good sense prevailed and I took it to the gunny at my LGS. He was concerned at first, but after a little study, recognized their was an alignment problem. Told me he was able to release the pressure on the spring plate, getting it re-aligned and the entire BCG came out. I told him that I had tried to knock it out, but began to think it was not going to work. Told me I was wise to stop as I would have caused a much bigger problem. Charge: $20.00 Best money I ever spent.

All is now good and lesson learned. Wife reminded me that to much "Confidence" can get you in trouble. Narrative ended with her "stay focused and go through the checklist you used to live by". I definitely drifted--"crashed and burned"--Hope my lesson will help others.

Appreciate all your help and support.

I can honestly say with 100% certainty you are not the first person this has happened to, I'm glad it worked out and enjoy the MPX.

Icarlos: Appreciate you reminding me that I am not a "one member" club. Hope that my carelessness will serve as a reminder to others and curtail membership in the club.

Brought the weapon home and broke it down and re-assembled three times. I was making sure it was "branded" in my memory bank.

Tough lesson, humbling; but time to move on and get back out to the range with my MPX.

Thank you for your words of support.

LOL!! Yeah, while I haven't made that particular mistake, I don't know how many times I've installed the Carriage Assembly, but forgot the darn Charging Handle!!??##..

I really don't like SIG's charging handles, but really haven't figured out how to load the rifle without one...

Cheers
