This video covers how to troubleshoot and fix magazine fitment issues (magazines that won't lock in).

Sent my scout back to SAI 2 weeks ago. Had to BANG the bottom of my CMI magazines to seat, magwell way too tight rear and rear sides. Lurking around here has been advantageous, got a sadlak guide waiting now, hated that kinked spring hanging out of oprod.

If your SAI had a new plastic/nylon style stock then magazine well tightness is probably due to the soft stock bulging in the magazine well if the trigger group is tight. I had to file the inside of a SAI stock recently that had tight magazine well fitment.

I never really noticed before. Man, you have nice hair! Congratulations!
Not the kind of comment I was expecting, but thanks! I must have had a good hair day.

Thanks, Tony. That cleared up some fitment problems I have been having with my scout. You might want to consider not showering with Muppermeat4me around-not implying anything but you know-lol

Thanks again Tony, good video.

I also learned a lot from your shimming video. It removed all the doubts about how to do the shimming and made two rifles shoot way better.

Thanks for that video Tony it made troubleshooting fitment of some mags a breeze.
I bought a new in the package GI mag and it didn't want to latch with out slamming on it.
I figured it was the parkerizing so I buffed the finish a bit and filed on the lug and its much better just needs to be used.

First off I need to thank Tony for the video. Nicely done. I thought I'd add my experience as well. My measurements were the same as Tony got prior to doing any fitting.



As you can see, when I hold the rear portion of the trigger housing flush with the stock there is a large gap where the front should be clamped to the stock. I decide to take .06 off the rear clamping surface to close this gap.



There was still a little gap in front after removing the material. This loosened up the trigger guard too much. I add .03 shims to the front clamping areas. The lockup is excellent now and my mags fit well. I will have to replace the shims with some bedding material.

Turns out my new in the package GI mag that didn't want to fit was bent.
Bent enough that the back of the mag by the catch had a large gap making the mag too long for the area it needs to fit it.
So a bit of pounding on that area with a plastic mallet and squeezing with a clamp I got it back to being square enough to fit in better than it was.
Inserts and locks in now just still a smidge tight but should loosen up over time.
