PSA microbest bcg.

Meh. He ran 7k rounds through that bolt, rifle and barrel..before the bolt failed. I don't think that so bad. Things WILL break. Nothing last forever. He says he got almost the same from the second bolt. The barrel was likely shot 3 or 4k rounds before that..especially seeing how they ran it super hot.

I doubt most issue service rifles ever see that many rounds..and if they do, they already went through depot a few times.

Im not condemning Tool craft for this.

Hell..even my extreme high dollar JPRifle BCG told me to change the bolt...a bolt made out of material even better than Captenter 158...at 5k rounds.

The vast majority of shooters on this forum...and even more out in general public...will NEVER run enough rounds to break even a cheap junk bolt.

Me thinks it's over reaction.

I will eventually, but it will be awhile. Anyone who reads much about ARs must know a bolt is a wear item and will need to be replaced. Heck, shoot enough and you'll need a new barrel.

I do wear out rifle barrels in my PRS rifles, something I'll probably not do in my regular rifles.
 
A lot of folks have a lot more than 7k rounds on Toolcraft bolts.

High cam-pin stress on the bolt is usually a consequence of extreme overgassing.

Seeing that kid’s videos show up from time to time over the years like this, I’ve always thought his unnatural expression was well fitting for his content. That uncomfortable cringing expression on his face matches well with the content on every video I’ve seen of his - super cringe.

I went through basic training, two AIT's and was permanent party at Fort Leonardwood in 1989 and 1990. We were still using the M16A1 for training units. The A1's used by the basic training companies definitely had high round counts. Rifles were always inspected on a regular basis by the unit armorers and having to replace the BCG or bolt wasn't all that common.

A couple of those were mine... ;) I often wonder what ever happened to HydraMatic #3360336...

In reality, most BT weapons have relatively few rounds cycled through them for each BT cycle... thinking back to 1986, I would have to say I fired less than 400 rounds, not including blanks... my AIT weapon even less. Now... do that over and over, every 8 weeks, and the round counts can stack up. Of course, none of the BCG components were ever swapped between rifles to pass inspection or anything... honest to goodness. ;)

How many rounds (live and blanks) fired also depended on if you were going through basis training for 12 series Combat Engineer or for non combat arms MOS's. I know basic for 12 Series did fire more rounds than basic training unit for all other MOS's when I was stationed at Lost In the Woods.

And yes while the round count per training cycle might not have been very high, the cumulative average per year was. And blanks can be as hard on the rifles as live ammo is.

And no BCG's were ever swapped between rifles o_O
 
Well... 12-series stayed for 12 weeks vs 8 weeks for we non-combat pukes... and certainly they fired more than we did.

I often wondered about blanks... being abusive to the bolt/gas system. They worked the action, but not like M193 did.

While blanks are not as powerful as M193 they are a whole lot dirtier since the blank firing device keeps all of the gases and carbon inside the rifle. All that carbon does cause issues, especially with the gas system. Granted a 1 week training exercise won't put too much carbon inside a rifle. But when you start talking about 1-2 month long training exercises without properly cleaning, that is a different ballgame.

I spent plenty of time training at Hohenfels Germany and my last duty station was NTC/Ft Irwin. I had reclassed from 12 series to 44E Machinist by the time I got to NTC and was assigned to 3rd Shop Maintenance.
 
I purchased an extra BCG and a spare bolt and keep them in one of my range bags, they both have been used and replaced by friends and fellow shooters who were strangers before. I also purchased an extra LPK and have taken parts out of it to help other shooters also. None of my replacement parts are "high end" Aero LPK and BCG came from Primary Arms but every shooter was happy I had an extre and none of their firearms had anywhere close to 7000 rnds one had less than 300. My 20"Colt still has the original BCG from the early 70s.
A friend decided he needed a better BCG for his 6mm ARC and I haven't seen any difference in accuracy and I can't imagine him shooting anywhere close to 5 or 7k rnds.
 
I just recently purchased my first AR15 and it is a budget priced package consisting of a PSA lower and a BCA upper. So far I am extremely pleased with the way it functions and it shoots sub 2 MOA with open sights. The BCG came with the BCA upper and I do not expect it to be a premium one but it works. What would be different if I had a more expensive BCG?

If it ain't broke, don't fix it. The bolt carrier, if it is in spec, will probably last forever. The bolt itself may wear but if it is in spec it should last many rounds. The weak point can be the extractor, or spring and O-ring for the extractor. Probably will last a long time. I like to have a spare bolt with extractor. I have had an out of sec BCG, I had to replace the BCG and bolt for it to function properly. On another rifle I had to replace the bolt although I could have replaced just the extractor. I did that and kept it as a spare.

It would probably last longer, depending on how much you shoot. But, as @d2wing posted before, if it's in specs, you'll have a lot of fun shooting before it breaks. And it will! So grab a spare one :)
 
PSA has several $70 bcg. Probably the same ones they put in the lower cost ARs. Any reason to not buy one of the $70 bcg?

The one BCG out of spec I had was PSA. Both bolt and bolt carrier were off. The bolt carrier was marked PSA. Small sample.
