#X-ray

Australian rifle company Lithgow Arms has introduced a new rifle for the precision rifle shooting (PRS) market. Called the LA-105 Woomera (after an Australian aboriginal type of general purpose atlatl or spear thrower), it is based on the Lithgow Arms LA102 centerfire bolt action rifle, but further accurized and fitted with a Kinetic Research Group developed chassis that is similar to both the Whiskey-3 and X-Ray chassis. The chassis features a simpler stock like the X-Ray, but M-LOK mounting points on the forend similar to the Whiskey-3 and Bravo chassis.

Well, the X-Ray was inconclusive. Let’s get a CT scan for a better look.  Last week we detailed Diagnostic Radiographer Brandon Bertolli’s analysis of his A-TEC CMM6 rimfire suppressor. He has since followed up with part two that includes additional observations of shooting 6000 rounds of .22lr through a suppressor without any maintenance.

‘Let’s get an X-ray and see what’s going on’. In a LinkedIn post entitled  Lead deposition in an A-TEC CMM4(6) rimfire suppressor: Part 1, Diagnostic Radiographer Brandon Bertolli uses a medical X-ray machine to chronicle the effects of shooting .22LR rimfire ammunition in a suppressor without any cleaning intervals. Although the results are somewhat obvious (it gets heavier and filled with lead), the use of the X-ray shows the location of the deposits and the gradual buildup over time.

Similar to X-Ray Guns, someone took their lower receiver and X-Rayed it. However this is a polymer lower. It almost looks invisible in the X-Ray image. I am surprised at the position of the buffer retainer. Look at how far forward it is canted. Perhaps that is just a characteristic of the polymer lower or do all buffer retainers lean that far forward?

I don’t normally think of sights as “optics” per-se, but Sig Sauer’s Electro-Optics division is rolling out their new X-RAY pistol sights. They’re a 3-dot tritium system, but these tritium inserts maintain a clean white color in daylight. You may have already seen them on Sig’s Legion series of handguns. The front sight is a green donut made from flourescent polymer with a distinctly smaller tritium dot in the center, while the rear white dots illuminate in low light.

IAA Forum user PaulSmith  received several x-ray images of ammunition, and was able to take photographs:

Photographer Nick Veasay used a number of x-ray machines to capture multiple images, many of which are firearms. Upon contacting the artist, he provided the following photos to TFB.
