Folks,
I just built my first Grendel. 18" Alexander Arms, Adams Arms Piston kit (micro adjustable block), etc.
I used a standard lower parts kit. I was having failure of the bolt to lock after last round (6 different Elander magazines: all had same issue). Also, sometimes the bolt would close without feeding a round. Sometimes it would jam up against a misfed round.
Adjusting the gas did not fix the issue.
So... I read a little bit. I changed out my standard weight (3.0 oz.) carbine bolt and tossed in an H2 (4.5 oz.) from Primary Arms.
Presto Magicko! All my feed and other issues were fixed.
Just wanted to say a "thanks" to the community. Without having to post a thread, I was able to learn for others' issues and the advice offered to them.
