  1. Perfect 5 Star Review

    Posted by on 15th Dec 2018

    Had small problems months ago with smaller gas block and tube. But not any more. Perfect fit on barrel, clamp on so it does not deform the barrel and a better seal IMO. I order them with the gas tube I need installed for a modest charge. Well worth the cost all the way around!

  2. what it should be 5 Star Review

    the gas block I got is exactly like it should be. The port openings were correct and also with lining up was correct. Very simple to adjust. The only thing I didn/t like was it did not come with the gas tube pin. Fortunedly I already had a couple.

    Only put a few boxes through and works flawlessly, I would also suggest in getting the allen wrenches, thought i knew where i had them, but had a hard time looking for them at the store

  4. Allen wrenches 4 Star Review

    The gas block looks like a quality piece. I had to lightly tap it onto my gas tube, appeared to be a little excess coating in the tube tunnel.. Other than that, it is a perfect looking and fitting replacement.
    I had to look several places to find an .05 Allen wrench.. Recommend buying those offered with the adjustable block. I still haven't yet found a long enough 5/64 to reach the adjustment screw under my handguard.

  5. Outstanding quality gas block! 5 Star Review

    This gas block was not only one of the best priced, but also reliable and athe functionality was perfect. I'll definitely be putting another one on my other rifle.

  6. Best value I've found 5 Star Review

    Posted by on 2nd Feb 2018

    This adjustable, clamp-on GB was the first Wojtek product I have tried. It was also my first clamp-on GB. Overall I was impressed with the quality of this product. My go-to adjustable GB has been Superlative Arms with the detent adjustments. The Wojtek is 1/3 the price and is still fully adjustable. I ordered a gas tube from them at the same time. It came with a roll pin and fit into this gas block nice and tightly. I will be ordering more from Wojtek in the future.

  7. Quality gas block at a great price 5 Star Review

    Posted by on 25th Dec 2017

    This is probably the best priced adjustable gas block you will find. I usually run jp adjustable clamp ons on all my builds but for half the price i think i have found a new go to.

    I haven't gotten to fire this build yet (450BM) but the fit and overall quality are very good. As long as it adjusts properly which I'm sure it will, this is a great buy.

  9. Good solid block at good price. 5 Star Review

    Well made. Adjustment screw is on the front, locking screw is on the side
    So they can be adjusted easily.

  10. .875 adjustable gas block 3 Star Review

    Posted by on 11th Oct 2017

    I bought this gas block to finish a .458 Socom build. It would not fit inside the Pantheon Arms Dolos Gen 2 handguard do to its height. I had to mill off part of the radius above the gas tube hole to make clearance so that I could attach the handguard. Other than that it seems decent for the price.
