Brass Hole In One – Compensator Failure

Remember those Roland Special malfunction spoofs? Well Nick Lui aka Ambergur Roselton on Facebook posted a video in his Facebook group, 3-Gun Calgary, of a rather spectacular compensator failure. He was shooting his compensated Glock but due to his focus on shooting he did not notice his comp had blown up. More importantly he did not notice the brass that fell into his compensator.

For those who cannot see the video, since it is on Facebook, Ambegur shoots his compensated Glock after almost dropping it. He is using Federal American Eagle 124gn FMJ. During a string of shots you can see the brass ejecting rather meekly. One manages to land right inside the large port at the top of the compensator. Talk about a hole-in-one! He did not notice this and fired the Glock. Ambergur had just finished working with kids at his Young Guns youth program.

I messaged Ambergur and he shared this YouTube video. It is shorter than the Facebook video but shows the Glock comp fail.

The brass is not stuck, this is just a screen shot of the brass as it falls into the compensator.

After he shoots the brass, that fell into the compensator, the gun malfunctions. He field strips the Glock thinking he had a squib. Ambergur does not notice the broken compensator and resumes shooting after reassembling the Glock. He experiences some misses although it is hard to tell as the audio is out of sync. He then shows a slow motion clip of the comp fail.

The comp is made by Toni Systems.

I do not know all the different compensators out there but the Toni Systems comp has a large top port that is wide open. The Archon Manufacturing comp that I reviewed earlier has small ports on top. Even the KKM Roland Special comp has small ports. So unless the top ribs are removed or broken off, there is no chance for an empty case to fall down inside.

I also question the rather weak ejection pattern of Ambergur’s modified Glock. The brass seems to just spill out of the gun rather than get thrown several feet like normal. This could also be a contributing factor to the comp fail. If the brass had been ejected like normal, it couldn’t land back down into the comp unless it bounced off a wall first.

I do like that this was captured on video. I am a huge proponent for filming while practicing. You can capture moments that you might have missed. Like in Ambergur’s case, he did not notice his comp fail but he did get it on camera. Filming your shooting practice is not just for capturing spectacular failures. You can re-watch what you did and correct mistakes you made. If you are interested in Ambergur’s developments of his Roland Special setup you can check out his website.

    I never had such problems with a 1911.

    Some people go way out of the way to complicate things.
