Finally got off that blasted castle nut on the flash suppressor and was able to mount my M1A NM in a FDE Troy MCS Chassis.... Now, however, it seems that the bolt is sticky, when you pull it back it sticks at about half way (seems to be when the bolt rotates...) and if you let it go slowly back it again sticks at about half way... After working it for a little bit it seems to stick less but it still does stick and I can feel it. Any suggestions? It never used to do this in the original stock...
