After about 500 rounds of mostly brass and about a 100 or so of the Wolf Classic the extractor broke, the extractor spring and ejector spring needed to be replaced. Just waiting to install all the replacement parts. Am hoping I will resume shooting with this upper. Does anyone else have experience with the steel cased wolf classic in an AR15? To say I am hesitant to use more of the wolf classic ammo is an understatement. If anyone can offer personal experience with the steel classic please don't hesitate to reply!
I have probably close too 1500 rounds of it shot through a 18 inch jp grendel and my 16 inch AA barrel both barrels used the jp bolt but the 16 inch is useing a maxim firearms bolt now due to me rebarreling the 18 to a 20 and useing that 18 to build a friend his first ar and first grendel.
Both my bolts are true grendel bolts and not the .125 face bolt that JSE uses with their barrels.
Hope this helps sir.
