Just installed one of these on my rifle. Really like it but I noticed that the replacement screw to attach your stock to the buffer tube doesn't have a hole down the middle like the one that came with my rifle. Will this be a problem?

The hole in your original screw is to drain water if you take it swimming.If your not going swimming wth your AR15 you will have no problems.SJR556.

SJR is correct, but there are other reasons as well. Besides drainage of water, the hole helps eliminate the possibility of "hydraulicing". Hydraulicing occurs when the air and/or liquid escapes slower then the compression of a piston or better known as the buffer. This problem of hydralicing will cause the weapon malfunctions, such as short-stroking. I've seen this problem before, especially when people stupidly oil their buffers. Personally, I recommend finding a screw with a blow hole, to make sure your gun does perform properly. It's critical to have the Bolt Carrier velocity to not be affected by the slightest amount of hydraulicing. ls

That is EXACTLY what I was thinking might happen. But, Aren't the flat places on the otherwise round buffer face designed to allow the air to escape as the buffer moves back? If I can't find a screw long enough (1 inch longer than standard) Could I get the same effect buy drilling a 1/32" hole in the tube near the end of the buffer tube inside the stock (did that make any sense)? Thanks.

The early AR15/SP1's had holes drilled in the receiver extension, located near the threads. They eliminated those holes due to some strength issues. But the holes in mention are a quarter inch in diameter. 1/32 probably won't hurt anything. Yes, the buffer has flats cut on the sides for that purpose, but action spring somewhat kills that theory. In other words, the spring seals to the buffer and the spring also seals with the buffertube, especially during compression. In the long run, I would recommend a screw with a blow-hole, but either way get a vent installed. ls
