I ordered these rings based on customer reviews and the vortex name. I have not had time to mount these as other parts for my build are backordered. I have however done a full visual inspection. Upon visual inspection I can verify that the rings look great. There are no mismatched rings or harsh edges/ledges. I lap all my rings and I will not comment on how the rings allign. I have never seen a pair of rings that didn't need lapping. Even if the allignment is perfect, there always seems to be some unevenness in the inner circumference of scope rings. Usually from thicker coating in one spot over another. The lugs are piccatinny width and perfect for my purposes. The screws fit tight and torque to spec just fine. I have no doubt that these will be great rings.

This is necessary for samson's handguards. Fit is tight. They want me to use more characters but this is about all I got.

The AR 15 was not designed or intended to run a piston. Which means every AR built with one is custom. A custom build will come with custom problems. Hand guard selection is tricky. Look on the Adams website for a full list of compatible handguards. An easy free float hand guard to slap right in is the Samson Evolution series. They utilize the mil spec barrel nut and are cake to install. Magpul makes a delta ring handguard that fits perfectly with this kit. I built a pistol upper with an Aero Precision Enhanced Gen 2 handguard. However, because the BAR barrel nut is taller than a milspec barrel nut you will have to mill out a recess for the rod bushing to rest in. For anyone utilizing this kit on a pistol length AR I suggest using the kit designed for the 300 AAC. After reading all the negative reviews I can honestly disregard all of them because of either installer error or someone not doing enough research for parts before deciding to build a "custom" firearm. I can't even shoot a GI AR anymore. I can't stand cleaning GI uppers. This AA piston kit delivers on it's promise of running 100% cleaner.
