I'm just extending a courtesy to my fellow members to remind you that, sometimes, a barrel is just a piece of crap.
I've been fighting a particular 5.56x45mm AR-15 barrel for over a year.
I have tried about 15 different types of ammunition (factory and reloads, 'standard' grade and match grade).
I have lapped the receiver.
I have bedded the barrel extension.
I tried free-floating the barrel.
I tried lapping the barrel.
I recrowned the barrel.
And I even tried it with and without the muzzle attachment.
Nada. Zip. Zilch. Absolutely NO improvement, since lapping the receiver (which shrank groups by 25-40%, depending upon the ammunition).
After a year's worth of work, 4 different ring and mount combinations, 4 different scopes, and far too much ammunition wasted on the thing, the best it will do is a 4.972" group ... at fifty yards!
So, it is now being retired from bullet launching service, and transferred to dedicated golf ball launching duty where it will only see blank cartridges for the rest of its time in my possession.
I know people are probably expecting a photo of a target. So, here it is. The BEST group this barrel has EVER shot. But keep in mind that it was overcast and raining; so image quality isn't stellar.
Holes that are difficult to see are highlighted in red.
And the group is placed so incredibly poorly because the scope (a good Redfield) ran out of adjustment, due to whatever it is that's so wrong with this barrel.
And one of the many forms this golf ball launcher can take on is "Space Gun".
(Complete with engraved Millet rings and a craptastic scope that sits so low that you can't actually use it! )
