I am an idiot. I was trying to figure out why you mounted your acog on the side of your gun. It took me way toooo long to realize that your gun was on its side.

Do you have a photo of the complete rifle?
3
If I look somewhere. It's just an MRP, nothing really special.
2
All AR-15's are special!

How does one keep track at all on round count?
2†
Microsoft has this great program, it's called Excel.
9
And just enter down to a single round how many you shot at the end of each range trip.
No need to be an ass. Simple question.
-1†
Know how many rounds you take with you, count what's left when you get home. Subtract the little number from the big number, and there's your rounds fired.
1
You bring rounds home from the range?
1
1 1 1 1
1
What optic are you running? Is that an old acog?
1
Yeah that's an old TA31 on an ARMS mount with an honest to God Docter.
7
Wooster Mountain? I can almost make out the numerous bowling pins.
1
What kind iron is on top of your optic?
1
It's not an Iron, it's a old school MRDS.
2
I see the glass now! I should have paid more attention. I figured it was something like that but I wasn't sure
1
This guy ARs... he ARs hard 0_o
1
Why up top did you say 77gr tears up the barrel? I can't find anything on it and am curious
1
Up until this point, what parts have your replaced? How often were they replaced? Thanks!
Barrels, obviously. I've sewer piped 2 10" barrels, one 14.5", and an 18" all in 5.56. I've also put down a 16" 6.8 barrel.
The bolt has cracked once, at the camming hole. 2 firing pins have dulled past reliable, and I've replaced the charging handle and trigger assembly because of wear and breakage. Your normal stuff too, springs and whatnot.
5 barrels in 30k seems excessive. Or am I just dumb?
I shot a lot of shitty bi-metal jacket and super hot ammo like Mk. 262 clones
How did you know your barrels needed to be replaced, and what round count were they? I exclusively shoot bi-metal ammo and am getting close to 5,000.
Normally a barrel should last at least 12k rounds. 20-28k on the nicer ones. Mines is project to last about 21- 24k
Yeah, again if you're shooting kind ammo. You take that 20K service life barrel and pump Mk. 262 and Bimetal through it, I bet you halve if not quarter your service life.
Rate of fire is a huge factor in this.
That does seem excessive, even for bi-metal. A friend who owns a gun shop/range just replaced the barrel on one of his rental ARs at ~50k. The throat was worn about 1/2", lol.
You've sent a lot of cash downrange, then
Had that gun for ten years now.
Holy shit dude. I shot 15k rounds through my upper many of those rounds were on full auto and didn't shoot out my barrel. It finally died at around 22k. The bolt is still running strong at well over 75k rounds.
There is a big variation in barrel quality.
On our range (instructors) we go through an average of 30 mags a day on some rifles, others more. Every day of the week, whole months. The grand total of which lands at around 30k. We've had rifles do more. The barrels go, but we replace them as needed, so I don't really know at what numbers it averages out. Every now and then a bolt or carrier goes. Charging handles are actually more common now that I think of it, but there's a clear difference here depending on which ones you're using. Our BCM's and DD's have lasted the longest for instance.
Buffer springs, selector switches, bolt catch and various springs. It all goes eventually, but charging handles and the little control things first.
