I've bought a few AR's but am new to doing a build so sorry if I ask some dumb questions. I just bought a ST LW50 barrel 6.8SPCII that 10.5 inches so my build will be based off it. I bought the barrel on a impulse and didn't read to much about ST and 6.8 specifically and more 6.8 in general. I was kind of surprise after I reach an agreement and started looking for information that I couldn't find anything about these barrels. Did ST decide to give up on the 6.8 game and when was the last time these were available? Other questions related to the build are:
1) What size gas block do I need, and what kind would be best? Do you need an adjustable with a short 6.8? Would it be better to use a clamp on block or have this barrel dimpled for one?
2) Where have the ST 6.8 bcg's gone. I'd like to use as many ST parts as possible, but have been having trouble finding them anywhere.
3) Any other suggestions for the build that I may have overlooked?
I guess I should have done more research into it, but in all the 6.8 vs 6.5 threads I've read the thing 6.8 had going for it was availability. Any help will be appreciated.
