Cycling Issues

I have a Socom II. I got it used. Recently, i was firing winchester ammo. I was trying to zero my scope on my Smiths Enterprise scope mount. I could not get the rifle to cycle well. I noticed that the ammo that i did get to cycle all had small dents on the proximal 3rd of the brass. After the first few rounds, the brass was getting stuck in battery. I was able to extract all of them but the second one was significantly more stuck than the first. I stopped firing after the second brass was stuck. The magazine on the right hand side shows my expended brass. Can anyone help or does anyone know of an experienced gunsmith in Phoenix?

Additionally, when unloaded, when i cycle the action, it is very rough and feels resistant to wanting to cycle at the onset. The further the charging handle is pulled, the smoother it feels.

First things first, did you detail strip and clean the rifle before shooting it? Lubricate it properly? Are those USGI magazines?

Eveything is well greased, not overly so. Same magazines as what came with it.

Thanks from JEFFJP_N_JJ

Check op rod alignment to the gas cylinder. Verify the gas ports are aligned. Is the brass scored?

Photo attached earlier shows the brass has small dent in proximal 3rd. Otherwise fine. The alignment looked good to me. Dont have rifle in my hands for the next few hours.

What are you shooting? Is it PPU perhaps?
Second, you say cycling is rough, this could be the trigger being cocked. That causes resistance.

If I understand, are you talking about a small dent on the brass AFTER it is ejected. If so, thats normal, it's your op-rod. Bolt moves back after firing, ejects, as the op-rod moves forward, it kicks the brass about 4-5 feet at the 2 o'clock position. You probably see some small brass nicks on top of the op-rod too. You may have other issues, but the dings on the brass are normal. Check your gas chamber alignment, by making sure the gas chamber port isn't cutting across your barrel port, rough chamber, op-rod binding on the guide, etc. -Lloyd

Do you clean the chamber with a chamber brush or a bottle brush wrapped with a patch?

Thanks from conditionone

I’d also say to clean the chamber very very well.

Those dents in the brass are totally normal for ejected rounds.

Grease everything properly and dry cycle the weapon several dozens of times. Then cycle a few full mags and give her another go.

I think you have a sticky or rough chamber.

Make sure none of that cheese grater stuff up front is rubbing on the operating rod.

Take out the piston and make sure it is clean and dry. Pull the oprod to the rear and perform the tilt test to make sure the piston is moving. With the piston out, shine a high intensity light thru the bore. You should see a perfectly round light when looking thru the relief port under the gas cylinder.

What ammunition are you using?

What kind of ammo? Were they handloads or commercial?

Thanks for the suggestions so far. I think my chamber is clean. I use a combination of nylon brushes, wood cotton swabs, etc..i'll give it another go over just to be sure. I will remove the piston and check for light reflection. I was using commercial Winchester ammo. Nothing terrible fancy. Im still not totally confident with this platform. I understood it to be much less finicky. Im much more familiar with the m-4 style platforms. I probably will not be able to re-clean it until this weekend. Consider that it'll be super scrubbed. No where to go anyways. I'll update after that. Many thanks to ALL of you. Your advice is well received!

Sorry, about the brass. Yes, i was referring to the small dent in the proximal 3rd of the brass as you may be able to kinda, sorta see in my picture. I don't recall having seen it previously. When your rifle isnt functioning well while in the middle of nowhere, it gives you time to notice smaller details. Possibly too much time. Again, many thanks.

Thanks from unkola

Old Newby, if you have the time, go to the home page, click on The M14 page, and on top you will see some stickies. Check out the Tony-Ben videos. He has them up for cleaning and greasing/oiling, disassembly/assembly, flash hider alignment, magazine fitting, etc. Tony spent a bit of time making these videos for the forum. Well worth the time watching. Good luck and remember, no such thing a dumb question when it comes to firearms. Hope this helps. -Lloyd

Thanks from Michigander
