Mini-30 Reassembly problem

I recently bought a new Mini-30 and love shooting it. I cleaned the barrel after each shooting and after about 4 trips to the range, I wanted to take it completely down and give it a good cleaning. I do this with my AR platforms and know them well and was hoping to gain that level of familiarity with my Mini. I followed the take down and cleaning videos listed on the Ruger site. Unfortunately the trigger group was not easy to put back into the gun. I had a hard time lining it up and may have forced it a bit too hard. I finally did get it back together but now the bolt action won't slide all the back way nor will the gun pull a round in when I insert a magazine and pull the charge handle. It kind of goes about 3/4 way back and never pulls in a round. If I remove the trigger group, the bolt and action work fine so something is not lining up with the trigger group. I followed instructions closely, made sure safety was on and hammer cocked as video shows when putting trigger group back. I've tried taking the trigger group out and putting it back several times and just can't get the rifle to work properly now.

Any suggestions? I was going to send the gun back to Ruger and will if necessary for repair but wanted to make sure it's not something simple that I'm overlooking that one of you experts might have come across before.

Thanks in advance for your help.

Seems you didn't have the safety in battery. I'm at work now so can't replicate your issue. Maybe someone else can chime in. Never force anything when reassembling a weapon.

Thanks Omega, I appreciate the help. What do you mean by safety in battery? The video online instructs to ensure hammer is cocked and safety on when reinserting the trigger group, which I did. However, I found lining up the trigger group so that it goes in smoothly and the trigger guard slides and locks back in place... very difficult and that's where I may have pushed too hard.

I have field stripped my mini's including my 1998 mini 30 more times than I can count, and every time the reinserting the bolt into the breech, and lining the trigger assembly up takes me a minute or maybe 30 seconds to complete. Funny thing is my M1A's and m1 garand's trigger group which is pretty much the same takes a minute to line up as well. Something else I thought about is do you have a synthetic or wood stock? Sometimes the action block in the wood stock, which has screws on the outside facing in at 9 o'clock and 3 o'clock may have worked loose and free play may contribute to this issue possibly. I usually loctite these screws in to prevent problems later. Just a thought! Also check to make sure if you took the bolt catch assembly apart during cleaning that it got reinstalled correctly, I could see where it could cause issues if installed incorrectly with the bolts movement.

I will also try to look at mine later and see if I can help you figure out whats causing it.

Thanks Tacky, appreciate any help. It's a new gun, the synthetic stock and stainless steel all weather Mini 30. I took it apart again today (just removed the trigger group and ensured that the stock and upper were together correctly) and reinserted the trigger group. It goes in nice and easy ( I got the hang of it ). But action still doesn't work right. When I pull the charging handle back the bolt seems to get stuck about 80-90% of the way but not a full pull back as to successfully chamber a round. It won't budge back and only forward if I push it. Yet if I take the trigger group out and hold the stock and upper together, the action works perfectly every time.

No problem, just out of curiousity do you have the magazine in it when you are trying it, or out? That may also cause issue if the mags not of good quality, if in fact you are trying it with the magazine in. I looked at mine and broke it down again to see if I might find a possible culprit, with the trigger group out make sure the hammer is seating fully, if not this could cause the bolt to not open all the way possibly. Just make sure its not binding. Another thing you can try is to remove the barrel assembly( action) from the stock, trigger group, etc. Assemble everything, trigger group to action minus the stock, assembling it that way may give you a look at whats hanging up, atleast it will be easier to spot with out the stock covering it up. Be extra careful to watch out for the recoil spring, and operating rod, without it in the stock it has no track to guide it and can misalign on the piston mounted to the gas block. Its also a finger getter. You may try to assemble it without the bolt catch in it and see if thats whats causing it. Just remove the cover, the bolt catch and spring. May also give you a clue. It sounds as if that may be it, since when the bolts at 90% open the bolt catch is interacting with it fixing to move up and stop the bolt upon ejecting the last round from the magazine. If all else fails give ruger a call, they have great customer service and I am sure they can help you out. Good Luck, and keep us posted!

Make sure that you didn't put the operating rod in upside down. I did this when I first got my mini 14 and it caused a similar problem? Also make sure the bolt open lock button and spring are properly lubed and installed correctly

Thanks for all of the replies and suggestions. Unfortunately nothing has worked. I haven't tried removing the bolt catch and may try that tonight. I did call Ruger customer service today and man you guys are right. They were awesome. Never once even asked for gun serial number or even my name and advised that they have seen a similar problem where upon reinserting the trigger group, if not lined up properly, you can stretch the trigger guard a bit and when it locks in place, it will bind the action. They suggested I tap lightly against the lock tab with a plastic mallet to see if I can get it to go back in and not bind up. They were awesome and said if I am uncomfortable doing this they'd give me an RMA right now. I'll try this tonight and taking out the bolt catch, although I don't think it's the problem as when the bolt jams, pressing the catch doesn't release it. I'll post an update later.

I fixed my gun! First, thanks to all who replied with great tips and advice. OK.. now the details: Tried gently hammering the trigger guard with a mallet as instructed by Ruger, no help. Tore the gun down again and noticed that even when just holding the upper, it seems like the action wasn't working right. I didn't notice this before. So I went to the source, the spring/recoil buffer. I remembered that when I took the gun down for the first time, I popped the spring and cleaned inside of the receiver etc... guess what? I discovered I had incorrectly reinserted the buffer guide rod. The buffer guide rod has a beveled head on it that only attaches to the buffer cross pin correctly if the elongated edge is down. As soon as I reversed this, I put the gun back together and the action works like new again. I'll take her to the range tomorrow to confirm but I'm sure that was it. I'm going to call Ruger and let them know once I confirm so they can add this to their list of stupid mistakes owners make! And as long as my gun is ok, I'm OK as I actually learned quite a bit about this rifle albeit the hard way, but that's how the best lessons are learned.

DAJ was right! I'm new to the Ruger platforms and didn't realize when he suggested the operating rod that was the same as the buffer guide rod. Makes sense now that I think of it. So DAJ... you the man you were 100% right and I thank you.

You know now that I think back I have had that happen to me as well, I had totally forgot about it, since now I run buffer tech recoil buffers in all my mini's it also makes it alot harder to mistakenly put the recoil spring on the bottom side of the pin instead of the top, but its great you are now up and running again, now get out to the range and send some rounds downrange.

The first time I reassembled my mini-14 I put the buffer guide rod in upside down myself and remembered a post I'd read here about that and immediately went to the guide rod and put it right.

Proper Orientation of Guide Rod

Just had the same issue, thanks to those who posted.

With the guide rod improperly inserted, it was difficult to pull the bolt all the way back,
you could feel binding and friction, and the bolt would not go forward on its own without a little push.
