I will get the list of suppliers listed on the new site which will be coming soon. I will let everyone know when it gets done.
As far as the gas tube, keep this in mind, the same carbon build up on your bolt carrier and bolt travels in that tube as well. When the carrier key separates from the gas tube the pressure is relieved through out the tube allowing some buildup to occur just like on your bolt. Although it is blasted every time you fire the weapon over time this can build up especially near the inner aft end of the tube and cause short stroking. The same carbon found on the aft end of the bolt is the same black carbon passing through your gas tube and in time can accumulate this is rare that it malfunctions the weapon but if someone wants to clean it, then this is the best I found for that. Wow can you believe all that for gas tube cleaners.......
Ok, I guess that is enough for now, except this, while at a local gun show I found some new mags with green followers, nice right...wrong some manufacturers are coloring the followers to match the green ones but are constructed different, just a note to look at them carefully, no one said green means the correct construction.
