I just went through a lot of posts on nubbin problems, most of it non-constructive criticism and flaming, so I'm going to say up front - that if you aren't going to offer real advise, call someone stupid - no matter how moronic the post, or flame in general, please move on to another thread - I don't want to bother scrolling all day to find answers.
That being said - I gouged out my brand new barrel very severely today. On a factory shipped AA Barrel - orings and P-Type nubbin pre-installed, the nubbin was bent inside the barrel and the sharp end of the wire gouged a very significant slash into the soft aluminum barrel. The gouge is located from the oval-shaped hole where the nubbin typically sticks out and extends nearly one quarter of an inch diagonally up and to the front of the barrel. There is wear on the opposite side of the barrel - the finish is rubbed off, most likely due to the bolt being pressed against the surface from the out-of-shape detent. The Nubbin still operated though - I was not experiencing ball breaks, ect - thus I was NOT AWARE that the nubbin had been damaged during play. I had made no attenpts to modify this barrel or adjust the nubbin in any way. As far as parts are concerned it was a recently purchased (October) Minimag and Barrel - the barrel was the only other functional non-stock part, so the gun can be considered right out of the box. I used the P-Nubbin after breaking two V nubbins (one in my stock 8" barrel and one in my SS Lapco Big Shot) one week ago and today.
I am not aware if my Bolt is "Long Nosed" or Short - I have no other bolts to compare it to - and I have no Mag buddies around to compare parts with. I am assuming long based off of posts about most new guns being shipped with long bolts.
I will admit that I short stoked the trigger a few times today probally around 5 - I am still getting used to the Mag's Trigger. I have watched the video closely and feel as though I have installed all of my nubbins properly and competantly. Two of the three nubbin breaks were factory installed nubbins.
Alright - Questions:
1)What is the comonality of the wire nubbin breaking - how often should I expect this to happen? Am I breaking more than average (on average, right now 1 every other day of play)
2) Is there anything I can do to prevent V-Nubbin breaks and P-Nubbin breaks?
3) When P-Nubbins break do they normally cause a serious gouge inside the barrel?
4) Is it possible for someone to post a picture of a properly (by the book - no personal mods that work >>great<<) positioned nubbin from the inside of the barrel's point of view so I can see exactly how far the nubbin should stick out?
5) Does the Long-Nosed bolt seem to produce more nubbin breaks to those who have used both for any significant legnth of time?
6)Are the plastic Nubbins publicly avalible yet - I am now fresh out of nubbins due to breaks.
I'm hoping some of you guys with some history working on Mags can answer these. i don't want to bother Rob or Tom with what seems to be a pretty basic problem, and remember guys, please don't post unless you are stating facts related to this post.
