Magpul MOE stock question

[The Electrician]

Finally got my stock, put it on it going from position 1-6 its real tight, is that normal at first? The tube is mil spec and the stock is also mil spec.

Its due to the manufacturing tolerances. Either the tube or the stock is a bit bigger or smaller, respectively. More than likely it's the tube. You can try sanding it with some fine grit sand paper or just buy a new tube.

My Magpul CTR stock was a little on the tight side to using a commercial size tube. It will be a little tight until the finish on the tube breaks in. I sprayed mine with some Jig A Loo dry silicone lubricant and it now slides slicker than snot. >> http://www.jigaloo.com/us/e_products_jigaloo.php
