I was finishing up my LR-308 build and decided I should check headspace yesterday before shooting it today.
Went to remove the ejector roll pin (using ejector removal tool) and roll pin wouldn't budge. Soaked overnight in Kroil and still no budging - one bent punch and one broken punch now.
In view of the above, it seems I have 3 options:
1. Toss bolt;
2. Drill out roll pin and replace with new roll pin (don't have on hand today);
3. Just shoot the damn thing and see what happens.
The bolt closes tight on live rounds (Norma 168 grain MKHPBT and dummy round I made up to proper OAL for .308 win) and the back of the carrier is flush with the back of the upper. So I do not think I have insufficient headspace. But I have no way of knowing if I have too much headspace short of shooting it and looking for signs on the brass and/or complete cartridge failure.
So, safe enough to shoot or not? Thoughts? I was going to strap it down to a table with some rope on a rest and go hide behind my truck. Then pull string to fire trigger. Seemed a bit extreme though.
All parts are DPMS including barrel and bolt. Next time I'm going with a Noveske build or Armalite.
ETA: Cartridges manually eject just fine.
