Installed one of the recoil buffers in my Mini 30. I found that my Promags will not feed the first two rounds with it in. Basically the operating rod is just barely coming back far enough to clear the mag with the buffer installed. With 10 rounds in the mag its a tight fit. I guess I need that extra 1/4 inch to get a little more umph. Kind of like a running start. I'm thinking about cutting the buffer in half. Basically splitting it and making it only 1/8" thick. Anyone else have the same problem?

I have read that bufers cause some problems with the Mini 14, like ejection/extraction .I made a buffer out of urethane and it works fine except for an occasional fault in extraction/ejection.Maybe you could try sanding it down at first.The thicker the material the greater the shock absorbtion, but I wonder how thick does it need to be? The Mini 14s is about 1/8", but I am going to sand mine down.Have you done a search of posts on "buffers" yet?

you should try a search on this - there's some of the exact same questions addressed. but basically I had the same problems when I dropped my buffer in. I trimed it down with an exacto knife - cut about 1/4 of it away and tried to sand out the unevenness. jams disappeared, but the bolt would still close on an empty clip which made for unecessary dry fires (I wasn't used to counting rounds, just looking for the open bolt). So, I threw the thing out. folks on this forum say though that after a "break-in" period the buffers are supposed to work a little better. I do recall it helped a little, but not som much so that I couldn't live without it.

I put in one of Mikes. Really cut down on the "clatter" and everything great. Then put in the largest of the 3 gasport inserts and got stovepipe jams, ejects but no pickup and sometimes no extraction at all. Changed out the insert to the standard again and all great again. Hunting brass is bothersome so I'm going to take the largest insert and drill it out about halfway in size between its orig size and that of the Ruger insert. Hopefully will get best of both worlds and be able to find brass without using metal detector!:rolleyes:

I'm kinda piggybacking on this post :)

I bought Mike's gas ports and the recoil buffer. I haven't had a chance to shoot it yet, but I have manually cycled a couple of clips without a hitch. Do you guys think I will have cycling probs when I take it out in the field? It wouldn't be a big deal to take the buffer out when I'm out shooting. I just wanted all your opinions:)

Doesn't a smaller gas port bushing let less gas into the pistion and thus reduce the ejection velocity?

Yup, that why I'm going to split the difference between the one that is so reduced it produces jams and the one that throws the brass 40'. The only choice is to start fooling with the spring on the return rod (increase/decrease) the tension the pressure has to compress to cycle the action, but thats not as easy to quantify as the gassport size. Aint it fun!!! Sure beats TV!!:D

Now the wife is snivelling that she wants one!!

Hey Billc. I had the same problem when working up handloads, droping down 10 % powder, and working up to pressure. Using the larger of Mikes bushings at the lower powder loads my mini would stove pipe till I came up to higher pressure. Using the Serria 63 gr SP @3000 fps the brass plops out about 10 ft, while the factory Winchester 45 gr @ 3600 fps flies about 25-30 ft. If I install the middle size bushing the Winchester plops about 10 ft, but my reloads stove pipe, or eject but does not cock. For a happy medium I use the larger of the 3 bushings.

I am going to order a brass catcher for range/target work as Im tired of loosing brass. Brass is money!

Bubba only one way to find out, and thats shoot it, I'd carry the tools, and a towel to work on so ya won't loose the little parts.;)
