Help! Trying to fix, but where to start?
My dad dropped his mini 14 off to me today. It's a couple years old, but barely used due to it's terrible accuracy. Started searching the web and the forum for answers. I'm sure you are all aware of what I found so I won't waste your time with that. Where to start? New barrel? Mo-rod? Gas block?
Any direction we be greatly appreciated!

Mo-rod and bedding the stock are good places to start

Thanks for the response. Looks like I'll be ordering one tomorrow.

Start with the gas block, back the screws off slowly and re-torque them down evenly as possible. If you have an in/lb torque wrench a tighten the screws back in a X pattern to 27-30 in/lbs.

The Mo rod takes a little time to dial in to the loads you are shooting. Start by setting it a 1/4" from the front site sight and shoot 3 shot groups, move forward and backward 1/8" at a time.
Try good ammo to, don't expect good groups from crap ammo.

I think one of the first things you should do is to have a trigger job done. The GunDoc does excellent work, reasonable pricing and very good turn around time. Check out I was really surprised how this affected my shooting. Many more steps after that, that can tweak that Mini-14 to where you want it, most of which you can do yourself.

Don't forget to get some rounds on paper as best you can to create a baseline for measuring your improvements.

Suggestion: 5 shots each from 3 types of ammo on separate targets, noted clearly with important info.

What kind of sights are you going to use? Makes a difference on which way to go. I have a 189 series Mini 30 that is now down to 2 moa slow fire from a rest with Wolf.
I re torqued the gas block and that helped so do that 1st. I installed a MoRod according to their instructions and that helped some more. I decided I wanted a forward mount optic to keep the receiver clear. You have to remove the optic to get the bolt out if it is mounted on the receiver. I bought an Amega rail that replaces the upper forend. It clamps to the barrel and also replaces the top of the gas block. It made the biggest difference. I was planning on a red dot but stuck a cheap 2.5X20 pistol scope I had on it to test for accuracy. 2 moa with Wolf ammo was very surprising. I think the Amega made the most difference. I have a small rail attached to the MoRod for a bipod so I am leaving it on. I should pull it and see how the accuracy is. The MoRod has 2 small set screws that clamp to the gas block but they dont hold well. I am debating drilling and pinning. I would probably try shooting without the MoRod before I do that. The sling loop attached to the gas block makes it hard to get a good angle on the screws to torque. I removed mine, drilled out the holes and replaced it with a removable sling loop.

Thanks for all the info guys! The gun shoots horribly. The serial # starts with a 197. At 100yds I would be lucky if all the shots hit the paper. A lot of vertical strings. We've ran a dozen weights and brands thru it with no noticeable difference. Shot some of my handloads with the same results. Looks like an adjustable gas block and a Mo-rod are my firsts purchases. Any recommendations on the gas block would help. Thanks again everybody.

I installed a "Mo-rod" of my own manufacture and it changed mine into a new gun! It's close to(or at) 1 MOA now.

Dont get an adjustable gas block until you try other things first. Torquing the screws is your first step. You might try something like this link before you get anything. If it does not hel it will attach to the MoRod for a bipod.
