I have purchased a number of these and i really like them - JE Machine Tech AR-15/M4 Adjustable 8 Position Fluted Buffer Tube

I have purchased a number of these 8 position buffer tubes and I really like them, they are well made and I like the ability to fine tune my length of pull on my rifles. If anyone else uses the rifles with these on them it’s the same story, they like the ability to select the best length of pull for themselves. My grand kids seem to be the ones that really notice the difference in the finer increments as opposed to the rifles my son has that are six position. Sometimes it’s the little things that make the biggest difference in life. Be safe, life is to short as it is without hurrying the process.
