Home-made pressure tester & similar testers for other markers (bushmaster lpr guage tool)
Gold Darq Marq
Ease of use, convience, simplicty and quality build
Confusing with out a manual or knowledge of how to use
I've used this product for sometime now and have had several different marqs with which I used it with. This device makes testing the LPR pressure extremly easy you remove the bolt engine and insert this device and it will test your HP & LP pressures at the same time. No need to remove hoses or grip frames or worry about breaking anything. I made a tester that I used for a while and this tool is much easier than it was to use. It defintely built well. The only problems I could see is that the orings can be rolled over on the tool if they are not lubed and there is no extras included and if the device is turned to the left or right it will not measure the pressure correctly.
Bob stands behind his stuff and this is a quality well built product with ease of use in mind will save you lots of time not breaking down your gun in order to test your LPR pressures.
