I'm not much for doing reviews, but Breek Arms deserves this one. They went above and beyond for a .875 low pro gas block that wasn't available on the web site but did come up with one. This was a very important part of my build before a competition only 2 days later. You guys impressed me with the speed and the shipping container protected it perfectly! 5 ☆ service!!
Affordable and great quality.
To loose on barrel. Leaking gas from everywhere
Way out of spec if your looking for a mid length or rifle length gas block look else where. Probably fine for suppressed, carbine or pistol length
I love what Breek Arms is doing here with this gas block, again you can't beat this deal. Fit and finish is premium! I like my gas blocks to be really snug, I want to have to force them on... this isn't that but it's real close to being that and it comes assembled with the gas tube of your choice. Again, can't be beat, I will also be using these on all of my future builds! I was using BCM and those a great, maybe better, but not for the money. For my money I'm going Breek Arms Gas Block + Tube on all of my future builds all day every day!
This is a well made gas block. Fit snugly over the gas block journal on my Ballistic Advantage barrel. Well finished. Includes some very nice knurled set screws. And comes with a few gas tube. Hard to beat. Knocked 1/2 star off for the included roll pin - it's design is quite different from what's typically used on an AR gas block... so I opted to use a normal spring pin in place of this supplied part.
