All barrel work is preformed on CNC machines. Our FSB installation service can be done to any barrel with any gas journal size. We machine the taper pin locations slightly below TDP so that we can remove slightly less material from the barrel.
We stock F/Non-F FSBs, for both .750"/.625"GB journals. We also carry the correct front sight posts(round for Non-F/square for F), springs/detents/taper pins.
We offer a few other options for the service...Our preference it to provide the FSB's (Schmid Tool), there can be dimensional variation of FSB's from vendor to vendor and we set up for the Shmid FSB's.
You can include your upper receiver, barrel nut, delta ring assembly, and end cap...or we can insert the taper pins with very little pressure so that you can install them at a later date.
