Okay ladies/gentleman, I decided to create a thread as it relates to a incident that I personally have experienced(scary as all *ell). So I have been around firearms for almost all of my life, and have always maintained proper safety and SA when handling any firearm, but I had a very crappy, and scary experience I thought I would like to share with all of you. So the story begins, one day after purchasing a used Mini-14 for a really decent price, test firing at their indoor range(several issues propped up with the weapon firing O/B several times, and the bolt would not go all the way forward), but since I bought the weapon(as in most weapons) "as is", I figured I would take it home clean and inspect for possible wear/damage. Well to get to the point, after cleaning, and stripping the weapon, I noticed nothing wrong with any of the parts that could cause the previous issues(bolt, firing pin, trigger group/springs and sear pin looked good), so I decided to cycle a few rounds manually(to test if the action was working correctly), everything was good, but when I placed a a new mag in the weapon(keep in mind the safety was on), I locked the bolt forward(it only locked about half way, so I gave the mag, bolt, and butt slight tap(pointing the weapon in a safe direction the ceiling, since I have roommates who live both down stairs, and adjacent to my room), and what do you know BOOM!! damn thing slam fired. My friend was watching me when it happened, other than the hole in my ceiling, and a ringing in my ears, no one was hurt, or injured, and nobody outside heard a thing.. I admit it was stupid act, but under normal circumstances(meaning a clean/good condition rifle) that is never suppose to happen. I hope anyone reading learns from my mistake, I have heard so many stories of slam fire's, and kind of had that "It can never happen to me mentality", given the Mini-14 operates the same as a M-1A, and the M-14 I figure I would post on this forum, also the weird thing is I have cleared similar issue's with several of my rifles by giving the bolt a slight push forward and never had a slam fire(not to say I should have never done it in my home for one). In the long run I got rid of that weapon, and purchased a M1A, and my god crafted beauty at it's finest. Thanks again ladies/gentlemen for reading my thread!!!
