View Full Version : Mossberg SPX Barrel Gas System Assembly...

Would someone be kind enough to post the assembly order of the gas system? Pictures would be great!. I removed the threaded ring that retains the heavy spring & seal ring for cleaning. Of couse they flew out & I don't know which goes in first or the proper orientation.
Thanks in advance.

Don't have the manual? It's right there. Don't recall the name of the items, but after bolt and trigger group are in, you put on the "U" shaped plastic thing, then the small spring, then the plastic tube, then the mag tube and barrel.
