Radian Afterburner & Ramjet Micro Glock Compensator, Glock 19 Gen 5 & G45
The Radian Afterburner + Ramjet introduce industry-leading recoil reduction while fitting into a conceal carry platform.
Afterburner™ + Ramjet™ together reduce recoil up to 44% when using 115g ammunition. At only .47” long, the Afterburner offers unprecedented performance in a micro compensator and is more effective than the majority of full-size compensators on the market.
Afterburner
The Intra-Lok™ mounting system uses the taper lock principle: a tapered locking pin interfaces with an angled V-groove on the underside of the barrel. This perfectly times the compensator. Angled front faces on the Afterburner aid in holstering.

Extremely easy install. Can’t wait to get to the range and try out the comp. I was kind of blown away by how quickly Rooftop Defense shipped my package. From order to my doorstep took about 2 days.

Fast, easy and amazing customer service from Sol and everyone at Rooftop.
As to the Afterburner+Ramjet, a noticeable difference in muzzle flip for my Glock. The craftsmanship and quality of every aspect of this product is unmatched— Radian did a great job.
Sol, I appreciate you for going above and beyond to ensure my purchase was A-1, and thank you for the Instant Ramen . I’m looking for plenty more business with you in the future.

Have this on a Glock 19.5 MOS. Great addition to the firearms. Definitely would recommend over the standard Glock barrel if you’re looking for good recoil reduction this is it. I find this setup to be very good when teaching students or first time shooters and a lot of fun to shoot myself and train with. I would go as far as to say that I would be comfortable competitively shooting with the setup I have and would go as far as to say think it would hold its own against the higher pistols. 10/10 would recommend barrel and comp. 5/5 easy install and the product performed better than I expected.
**THIS WILL NOT REMOVE ALL RECOIL/FLIP BUT IS A NOTICEABLE DIFFERENCE FROM STOCK COMPONENTS**

Shipping was extremely fast and the product does exactly what it’s designed to do. My pistol’s recoil was so flat I actually had to re-zero my optic as my initial zero was roughly 2″ high @ 25 yards; however, I didn’t notice this while shooting with the OEM barrel, etc.
Rooftop Defense was practically the only place I could find this barrel/comp. The Ramen noodles that came with my order was a nice touch. I’d highly recommend buying from Rooftop Defense!

I ordered this for a Glock 19x, and so far it seems to be a pretty good upgrade over the stock barrel. I seem to have a little bit better groupings at 25 yards than I had with the stock barrel. There is a noticeable decrease in recoil, fairly similar to the Parker mountain comp’s that I have on other guns. I had a couple of light primer strikes with some Winchester ammo, but that is the only failures that I’ve had since I put the barrel in the gun; but I also had the ammo fail in two other guns with the same issue, so I would put that up to a ammo issue. I would recommend this to others, if you are willing to spend +/- half of the price of the gun you are putting it in.
