[THE DOCTOR]

I received them in a timely manner good fit and finish excellent price.

I had to modify one a bit for my own special purpose situation but for a normal carbine length tube it would not have had to be done. (I ordered 2 and the carbine install went without a hitch) The mod i made was to bend and shorten the pin that is used to select the gas port so that it would clear the free float tube with this mod i also had to mill a slot in my free float tube. I am a machinist so no big deal.

I am very happy with the gas block especially for the price especially as this is a niche part.

Thanks for building a quality part at a great price
