Size matters

With a mid length gas system, what length HG barely covers the gas block. I’m thinking 13 in but not sure

I don’t need a lot of rail and want to keep it somewhat lite for mobility.

I was wondering if a guy had an adjustable gas block would he need it exposed for adjustments.    I've not tackled a build yet so that is obviously a novice question.  Could be they are adjustable through the access inherent with the HGs.

I have several adjustable blocks that are buried, just careful to use one that can be worked from the front with an extended tool. I have one I can worm my way in on the side but that is not as handy as a long tool from the front. I worry about it less and less, find that after the initial adjustment I rarely have the need to re-adjust.

Thanks JT.

I think I am down to two.   Have not researched this faxon yet, i.e., would like to know if they have a bolt to sell with it.

The other is the AERO BA 20" CMV offering now back in stock (or was a minute ago).   

The Faxon would make a 9lb out of an otherwise 10lb rifle, no mag or scope.   Just iron sights in that weight.

geeze, did I get lost and plunk that down in the wrong thread!
