Does an Adams Arms Carbine Piston Kit work with an Armalite SPR Mod 1 COP Carbine Kit? Or is there not enough space for the op-rod under the top-rail? Are gasblock-rail and top-rail on the same level?

Hey...if it turns out there isn't enuff room under the rail you can do what I did. just dremeled out under the rail a bit & it fit perfect. I run an Adams Arms piston kit on my Bushy Ar15 SBR. Purrs like a kitten. No hiccups from day numero uno!!
