I know a lot of you have worked with adjustable gas devices to tune you Grendels, so I thought I'd ask here.
I have an over-gassed .308 and the common corrective action is an adjustable gas block or tube.
My question is which is preferable? The only factor to me would be a block fits a given barrel diameter and if you get rid of the rifle, you have a block that may not fit any other barrel you own. A tube, while obviously you have to decide the length you need, can move to another setup with the same length gas system.
Also, what about reliability and maintainance. Is there a strong opinion WRT that between the block and the tube variety?
Thanks,
