UNIQUETEK - Gas Block Aligner 30 Caliber

This tool is a great addition to the tool box. I won't assemble a gas block without using this device. Six different sized inserts are provided and I have used two of them in .223 barrels. Once used, the used insert is discarded. Works well and I keep some on hand. I use this tool in conjunction with other tools to ensure I have the best alignment of the gas hole possible.

I noticed that there were some that had problems using these. The pins work fine IF you are sure to degrease the Gas Port in the barrel with Alcohol and be sure it is completely DRY!

Works as advertised. Be sure to clean the gas port in the barrel with alcohol to eliminate any oil that will cause the pin to stick in barrel port. Once cleaned and completely dry the pin can move freely through the barrel Port.

Although a little pricey for a "use it once and throw it away" tool, it is simply the quickest and most accurate tool for perfect gas block alignments ever. This is truly the best tool for the job! I won't do a build w/o them. Genius! Dr. S.

Did my first two AR's tonight using this gadget. One was a heavy/bull barrel and other was a standard .750. Both gas blocks were vintage with rails built in. Read the instructions, watched a couple videos on YouTube then got going. Cleaned out the barrel ports per instructions. Dropped in the little sticks which went without a hitch. I did discover one gas block was generously sized so I had to pick the best "middle" position. Both fell into place and blocks tightened. Both snapped off easily with a cleaning rod. This is much cheaper than buying a bore scope and certainly much better than guessing by eye and hoping the holes are lined up. Highly recommend and will be buying more of these.
