Gas Block installed without a hitch with set screws. Gas Tube fit perfectly into the Block and the upper receiver.
Happy w this purchase and how it fit on my gun.
Goes great with my SAM-R, AND KMR Alpha 15.
Great quality and performance. Put this on .300 blackout barrel. Seated easily and correctly. My second gas block from BCM. Exceeds all expectations.
I have been using these gas blocks on my builds for a long time. Recently tried a different brand and the fit to the barrel was loose which led to cycling problems due to gas leakage. Removing the loose one and throwing it away and doing what I should of done in the first place. Going with BCM
This gas block lock's down so tight no need for barrel dimple. You can buy many different gas blocks for a lot less..... but what is your life worth?
Had I'd know during my planning process I would end up buying all bcm upper (18" 410 as barrel, 15" kmr alpha,bcm lo-pro gas block & tube,demo bcm upper receiver, bcm bcg, ambi-charging handle) I'd have gone with a completed upper, as I think it's really cool all the free swag they include with their products, as well as saved me $ & assembly time.
As for the gas block, its every thing you'd expect from a reputable company like BCM. Simple but well packaged, good fit and finish as the pre drilled dimple on the bcm barrel will make install simple. To me the thing that seperates bcm from other companies on the market is their commitment to quality, innovation are second to none as they are constantly setting the bar & driving the industry forward In the pursuit of excellence. Every detail matters,(even a gas block) so when it comes to personally choosing a product that contributes to me being able to defend my life, only one name comes to mind, bcm.
It works flawlessly, cycles correctly and it stayed in place after a day at the range. I will be ordering another for my next build.
