Drain Holes in Rx Extensions....
Can anyone tell me what the TDP says about this? I've always thought the Milspec buffer tubes/Rx Ext's were supposed to have drain holes located in the bottom, which were supposed to be drilled in the middle of each hole used for the positioning of the collapsible stock. Is this correct? My LMT Rx Ext has three of these holes, which I THOUGHT were drain holes.
However, my Colt 6920 does NOT have these three drain holes. There IS one hole drilled in the END of the tube, but I think that is where the tube was machined, or held by a fixture during the machining process?? Possibly turned on a lathe?
Anyhow, does anyone know about these drain holes, and where they are supposed to be located? Is this whole "drain hole" issue indeed a thing of reality, or do they even exist??? It seemed odd that my LMT would have them, but my Colt doesn't???
