I need some advise. I just built a 308(cmmg lower,fulton upper and barrel,rainer bolt). When I got done with the build I took out and shot it with no issues. It fed fired and extracted. I had to take the forearm off and return it(that was another post). When the new forend got here I put it back together now if I let the bolt return slowly it will not chamber the round all the way. if I let it slam it will chamber the round but it takes a lot of force to extract the unfired round. My reloads will not chamber at all. I'm guessing its a headspace issue but why would it change after just changing the forearm and barrel nut.
Thanks Schultz |

Did you have the BBL. off ?
How many rds. were through the rifle before you removed & replaced the HG. ? If you slowly release the BCG ,it will hang up most of the time . If low rd. count ,its going to be tight . Check your reloads, may be a COL problem or case sizing problem . |

Hiya! try some factory stuff first. On your other post bout the troy being loose....what did troy find out and how did they solve the problem? Mine didnt have a tab like the 6.8 I showed you.Mine is still tight with the two lil bolts though....i guess time will tell?

I tried some factory stuff and it shot alright but there is what I think is an ejecter mark on the brass.But no other pressure signs. I am ordering my comp in a week or too I then plan on doing more shooting with it. I am going to an advanced AR armor school this week and I am going to take the 308 and check the headspace.Troy replaced the forend with a new one and it fits alot tighter. They also sent along one of thier new mags(nice suprise). Troy was very easy to deal with.

I thought i had a headspace prob on my build....checked it and it was fine .... it was just crappy privi ammo that was blowing primers . a new mag? Wow .. yep troy is nice to deal with! Wash |
