Installation differs from the AR-15 in that the LR-308 is retained with a shoulder screw rather than a driven roll pin. There are two small springs of this approximate size in the kit. The uniform diameter spring is the correct one for this assembly. The spring is dropped into the receiver well, the buffer is dropped in with the big end up - I used tweezers after the fourth attempt, then the catch is pressed into position. The unthreaded shaft of the screw allows it to be used to locate the catch in position and held before it is necessary to use a 1/16" hex wrench to tighten it down. I put a half drop of blue thread locker on the thread just before tightening. It is a shoulder fastener so it can be tightened all the way without impeding movement of the catch. The bolt catch is ops checked for full travel without binding, magazine in or out.
