So incase you didn't see my other thread I finished changing and pinning my fixed stock on my mp15 sport. One thing I just thought of though was the modification I needed to make on the stock tube was to drill the one hole bigger to 5/16th. I did though drill all the way through to the bottom of the tune. Being a newb I'm not sure if this an issue or not. Any help is appreciated! 

Side note, nothing protrudes the tube, it's just the hole

What do you mean you had to drill it out? 

Are you talking about drilling out one of the adjustment holes? As long as there's no debris on the inside of the tube (metal shavings, raised lip on the hole, etc) I don't see how it would affect function.

Your question is a bit sketchy (at best), possible you could give us more to go on?

 

I think you mean you drilled out a pinned stock, and drilled through the buffer tube

wall and into the tube itself - correct?

 

Can you post a photo or two if where you drilled this hole......?????

sorry for the confusion but yes you are correct. it was to increase the size of the adjustment hole. i made sure to clean out the tube of all shavings and there is no raised lip on the hole

You will be fine in it is simply one of the adjustment lock pin holes drilled through with no burr on top or the bolt/rod I'm assuming you installed in place of the adjustment pin does not extend up into the spring cavity of the tube
