Removing thermal fit barrels can be a challenge.
Use these shop fixtures with a standard shop press to gently remove stubborn barrels without damage to the barrel or the upper receiver.
AR15 version uses 1 1/4 - 18 pitch threads for use on any AR-15 upper.
SR-25 / LR-308 version is for the noted styles of upper receiver that use 1 7/16 - 16 pitch threads, These will not work with Armalite AR-10 guns with 1 7/16 - 18 pitch threads
Each press fixture comes with an aluminum press rod to slide into the receiver to press out the barrel without damaging it.
