Gas block

The delivery time was fast. Gas block and tube looked good. When installing on to the Barrel it would not go on. On closer look I found some hanging metal. I had to cleen it up. The gas tube was great. Instead on a BA barrel and AT3 upper.
When installing hand gard the m lock hold down nuts for the picatinny rail for bipod hit the gas block after some Minor Adjustments to nuts. Installed handguard looks great I'll just got to go and shoot it.

Thanks for sharing some pics, Kyle. Looking really great! -- LM
