It also will not chamber a either a 5.56 or .223 round with the 3 mentioned newer/new bolt carrier groups
I did pick up a mil surp colt bolt very used and this will close on a go gauge with a little force used . and it will also chamber new ammo both 5.56 and .223 on its own with just the use of a buffer spring or by hand it does not require as much force by hand as is it does with the gauge seem pretty norma . how ever it would not close on a reload i believe its a factory reload actually just a random round i have.
Oly says this is normal with their barrels and wants to charge $20+ shipping to fix a problem that to me seems to be a factory issue they claim all their bolts are head spaced to their rifles for precision fit and when switching bolts with their barrels they must be headspaced.
They wont do it unless I send them one of their bolts its gonna cost me $50 alone to send the barrel in pay for all the shipping and for them to fix a problem that should not exist.
perhaps the old used bolt i have will solve the problem maybe or if its a chamber issue maybe not. To me if it takes a warn bolt to chamber a round and new bolts do not work in it to me its a faulty barrel
I have asked if i find a bolt that will chamber a round and close on a go gauge if it would work they will not answer that question in fact they flat out ignore it as if i did not ask it .
