AR-15 .......Stopped counting at 12,000 rounds...
I know this is a bit off topic from this thread, but I still have my AR-15 Colt HBAR that I bought brand new in 1987 or 88...It has been fed a steady diet of Georgia Arms reloads (55 gr. USGI duplicate load).....and I stopped counting at 12,000 rounds...probably has more like 14,000 down the tube, total...
Never rebarreled it, and the bore still shines like a mirror....I'm sure the throat erosion is probably off the charts, but the rifle still puts every round in a 3" black bull at 100 yds.
I'm very over-the-top about cleaning my guns, and have NEVER put one away "dirty"...so maybe the constant cleaning helped?
