We only use Military spec primers which means a harder base to avoid taping and sending the weapon into full auto. I have shot weapons that went into full auto (with commercial primers) and it is a scary thing to say the least. As most know the free floating firing pin of an AR causes this problem and is why the military requires the harder primer.
Even though what appears to be a good strike may not, it could be border line, with some firing and some not. Taking apart the bolt and cleaning the firing pin is a must
An AR is a military weapon not a target rifle, light hammer springs or light trigger pulls with a free floating firing pin is not a good thing.
We supply nearly all 6.8 gun manufacturers with ammo for testing, which includes but limited too, LWRCI, POF, Stag, Rock River, and PRI none of which reported problems. But with that said we had a spring on one of our lowers go bad and it had to be replaced.
There maybe a spot problem they we do not see with the CCi mil-spec primers, but why is it relagated to a few guns or someone that has a consistant problem while others do no have issues. With nearly 2,000 online customers you would think there would be an overwhelming out cry from our customers.
If we go to a commercial primer than we have to look at product liablity issues.
Please weight in as we want to do the right thing and feed back will be helpfull.
