Setup & Operation
Step-by-step procedures for setting up, operating, and maintaining the RAMJET + AFTERBURNER for Glock 19 / 45 Gen 6.
Install the RAMJET Barrel and AFTERBURNER Compensator
Installation is a standard barrel swap followed by clamping the AFTERBURNER onto the RAMJET with the INTRA-LOK taper-lock screw. The RAMJET drops into the slide like a factory barrel; the AFTERBURNER slides over the muzzle end and is held by a single tapered screw, with no Loctite, shims, or muzzle threads involved.
Work on a Gen 6 G19 or G45 slide only. The Gen 6 RAMJET clears a frame tab that the Gen 5 part does not, so a Gen 5 AFTERBURNER + RAMJET must never be fitted to a Gen 6 pistol.

- • Inch-pound torque driver
- • Light gun oil
- 01
Clear and field strip the pistol
Drop the magazine, lock the slide back, and visually and physically inspect the chamber to confirm the pistol is unloaded. Field strip the Gen 6 G19 or G45 per the Glock manual, then remove the recoil spring assembly and the factory barrel from the slide.
- 02
Oil and seat the RAMJET barrel
Apply a light coat of gun oil to the RAMJET barrel exterior and barrel hood, then install the RAMJET into the slide in place of the factory barrel. Reinstall the factory recoil spring assembly behind it.
- 03
Clamp the AFTERBURNER onto the RAMJET
Slide the AFTERBURNER micro-compensator over the muzzle end of the RAMJET barrel and align the tapered locking screw with the angled V-groove on the underside of the barrel. The V-groove indexes the compensator, so it self-times as the screw draws down.
- 04
Torque the INTRA-LOK screw to 15 in-lb
Tighten the tapered T10 screw to exactly 15 in-lb. Do not overtighten; exceeding the spec can damage the INTRA-LOK taper-lock system. The taper draws the compensator down onto the upper barrel profile, so no thread timing or crush washer is needed.
- 05
Reassemble and function test
Reinstall the assembled slide onto the frame and rack it to confirm normal slide travel. Function test the pistol before carry or live fire, since adding the comped barrel changes the slide's reciprocating mass and can require lubrication, ammunition, or recoil spring adjustments.
Stop at 15 in-lb on the INTRA-LOK screw. Overtightening can damage the taper-lock interface, and unlike a threaded comp there is no crush washer to absorb extra torque.
Confirm Reliable Cycling After the Swap
A compensator vents gas and changes how the slide cycles, so the RAMJET + AFTERBURNER can shift your pistol's timing. Radian explicitly notes the system may require adjustments to lubrication, ammunition, or recoil spring before it runs reliably.
Verify function before trusting the pistol for carry. Heavier 124gr and 147gr loads generally cycle a comped Glock more positively than light, low-pressure 115gr practice ammo, so use defensive-weight ammunition for any reliability check.
If you see short-stroking, failures to return to battery, or brass landing weakly with light 115gr ammo, test a heavier load or a fresh factory recoil spring assembly before assuming the part is at fault.
Prevent and Clear Carbon Lock
Combustion carbon builds up at the RAMJET-to-AFTERBURNER interface and can seize the compensator to the barrel over a high round count. Preventing it is a one-step habit at install time.
Before seating the AFTERBURNER on the RAMJET, coat the barrel-to-compensator interface with a heat-resistant gun oil. If the compensator does become carbon locked, submerge the assembled AFTERBURNER and RAMJET in gun oil or CLP overnight, then spin the compensator to break it free. Re-oil the interface whenever you remove the AFTERBURNER for cleaning.
