I am having an issue where when I fire the weapon I only get one round at a time I have to manually cycle the bolt carriage and in some cases it attempts to cycle but it jammes a new round up against the old round also when I have noticed that the bolt does not set correctly and I have had to use the forward assist a couple of times when I tried to manually eject and put a new round in I have a aftermarket gas block on it and I'm not sure if this is all caused by an improper gas seal or improper gas block or if there is other items I need to have looked at like possible a new bolt assembly

Did you install the gas tube upside down, gas port pointing to the sky instead of down to the gas port hole on top of barrel, Seen it done. Did it work before you made the changes? If the answer to this last question is Yes, them you have mucked something up, NO big deal just trouble shoot it and fix the problem, wolf ammo will short stroke, let us know how it turns out,

The bolt not going fully into battery could be a symptom of a short stroking problem. Does the BCG lock back on the last round of a mag? if not then a short stroke problem is what you have and there can be many causes to short stroking from ammo to gas leaks. Did you install the aftermarket GB? if so did you install a HG end cap behind the GB and if not did you space the GB off the shoulder (like the end cap was there) about 1/16" for proper alignment of the gas port? Also check your gas key on the carrier to make sure the bolts are tight and they are still mated together correctly and that there are no leaks. Also check your gas tube alignment ... remove bolt from carrier ... slide carrier into the upper until it engages the gas tube ... is there any resistance there? Also have you thoroughly cleaned (paying special attention to the chamber with a good solvent and a chamber brush) and lubed the rifle lately?
