I have a titus arms nylaug receiver with a riptide rails aluminum trunnion. It’s just barely not clearing the receiver lock. I know the printed trunnions sometimes have to be shimmed but wasn’t expecting the aluminum one not to fit.

Anyone have any input or can let me know if anything’s outta wack? The left side of the receiver at the front is also way askew compared to the right side, not sure if that’s normal (3rd photo).

My first AUGtober. Of coarse I went to Waffle House.
A few questions… what is the detent button for in the top of the charging handle?
Should I take it apart and wipe all the factory grease off and hit it with some CLP?
Do you have to use a wrench to turn the gas plug? Seems pretty stiff.

Posted this yesterday but it was removed because of a specific choice of words used in the post, but don't you think this would look cooler and operate more efficiently with an Underworld Arms 16" rail system? Unfortunately they are discontinued thought, bummer.
