Hey everyone! So I finally got to take my new build to the range yesterday and try it out. In short, after a couple FTF (bolt caught on round still partly in the mag) I'm really stuck.
First, a quick rundown of what I've got:
Relevant gun info: AA 18" barrel with mid-length gas system, SLR Ti adjustable gas block, Franklin BFS trigger (comes with 'regular' and 'heavy' buffer springs), Spike's T1 carbine buffer.
Ammo used: Wolf steel-cased (maybe a poor choice for breaking in, in hindsight)
Mag: e-lander 10 round (from AA)
Started with gas block in middle setting, using heavier spring
1st FTF looked _exactly_ like the one in this thread:
Seemed finicky, so after a couple shots I swapped in the lighter buffer spring.
2nd FTF the round was mostly in the chamber, but not all the way. Needed a friend to pull down on the charging handle to free the round.
Adjusted the gas block 2 clicks for a bit more gas. Ran a string of 5 shots no problem, then on the 6th...
3rd FTF - where I'm stuck right now. This round is jammed partly in the chamber hard, and my friend couldn't pull the charging handle down. It's STUCK.
Question 1: (Most important) What is my best approach to free the jammed (steel cased) round? Should I mortar it? I'd hate to bash a brand new build so hard on the ground, but I'd also hate to have to pull the whole darn thing apart already. Still, I'll do what's best and with minimal damage.

Question 2: Potential causes of my FTFs? As noted in the thread above, should I try a heavier buffer, like the T2 (1 step up)? And/or should I try dialing back the gas, or dial it up? Should I leave the lighter spring or go back to the heavier with more gas? Gah - so many combinations, I'm not sure where to start!
Thanks in advance for any advice!
