Have you ever considered trying a few LMT enhanced bolts?
Supposedly they've never heard of one breaking. Might be the ticket for the heavy use you are putting the ARs through. Just a thought. BTW, great thread and great info, thank you! |

We don't use it that often but now that we have our upgraded M107A1 headed back from Barrett, it will start to be used on a regular basis. V/R Ron |

My RSO's are tasked with customer safety first and then customer satisfaction. They couldn't provide both of those and try and keep track of weapons jamming and take the info back to the armorers without the first two starting to lack. If a weapon jams once, there's a good chance it was user-related but a second jam means the customer gets a new weapon and they start all over with a fresh magazine, even if they got 24 out of 25 rounds down range. Most of the customers won't take the additional magazine because they feel guilty but it's worth the cost of the ammo to make sure leave with a huge grin and satisfied. V/R Ron |

Just wanted to take the time to thank you for chiming in on your experiences, it is definitely appreciated. I will echo what others have said and would like to see you add a few offerings from Knights Armament to your inventory. The SR25 series, in my opinion, are one of the best semi auto gas guns available but, I would definitely like to see how their SR16 series hold up compared to the others you current have in rotation.
Keep the information coming, you for sure have a captive audience. |

Thanks for posting the information.
Since you actually do shoot so much through the rifles, I am curious just how well the CHF "machine gun steel" barrels with heavy chrome lining hold up. Granted, you mentioned that you are only shooting for close range, but it would be interesting to see just how much more these barrels hold their accuracy over other barrels. I have some of these CHF barrels, and I like them just fine, but I'll never be able to put tens of thousands of rounds through mine! |

Thank you for taking the time from your business to answer our questions. I haven't read anything stated by the OP that I would say "clearly" one outlasts the other. Other than the "one" HF MR556 barrel only lasted 10k rounds. I might have missed one, but below is what I gathered the OP stated about barrels. Some of our M4's have well over 200,000 rounds down range. Barrels have been replaced
At what rd count we're these barrels replaced and were the HF or not? I purchased a FACTORY brand-new MR556 and it started keyholing after only 10,000 rounds. One, correct? edit: just read the MR556 is NOT chrome lined. Not really fair to compare that. I had barrels from before we even opened the range with 1,000's of rounds on them from J&T Distributing (chrome-lined) that didn't keyhole well into the 80,000-100,000 range. Don't know much at J&T, we're any of these barrels HF? As for barrels, a majority of the barrels are DD and LMT. Are you getting the same 80k-100k out of these? The same goes with the barrels. I was BLOWN away one day when I walked back into the armory and one of the armorers said "doc, I hope you don't get pissed but one of your original barrels is done". I was the completely opposite of mad because I couldn't believe a J&T barrel lasted that long when I've always believe the old "25,000-30,000" barrel life for an AR/M4. It opened my eyes to all the things that I read previously and never had the time or money (wife has ALWAYS held on tight to the purse strings) to go shoot 50,000 rounds down range and verify for myself. I stand by the standard vs HF barrel life are about equal. Nothing to back up this claim, but I have yet to see anything that "proves" HF last longer. Perhaps the OP has the best evidence to date on this... |

Best Thread Evah!
There's a lot of info here, some of it surprising. To summarize the various replys so far from the OP: - Brownell's GI mags outlast PMags. They outlast everything in fact. That, I would not have expected. - With some possible exceptions, piston AR's don't hold up. Again, not something I would have expected. I personally always thought they were a gimmick, but didn't think any but the crudest renditions would fail any faster than DI. - Changing handles fail. Again, unexpected. I just figured it's a near static piece that would last basically forever. - No comment on extractors. I would have thought those would fail faster than the cam pin or lugs. That said, perhaps an oversite to mention by HndersonDefense, or possibly they are considered consumables and just not even worth noting? - Apparently Bolt's and BCG's aren't all the same after all (a common mantra here). DD and LMT bolts hold up better than all others. - Good barrels are lasting much much longer than the ~25,000 round expectation (though not clear what the round count actually is). That's incredible. These are full auto guns. That has got to be wearing out BBL's way faster than more normal semi-auto fire (heat). Details aren't completely clear, but it's sounding like hammer forged barrels hold up better(?). A barrel is considered a crappy BBL if it only lasts 10k rounds. - Short barrel rifles have much faster throat erosion. I don't know why, you'd think they'd be under less heat for a shorter period of time. At a guess, maybe it's because the early pressure release (bullet exits sooner), allows the chamber contents of hot and large kernels of still-burning powder to eject down the barrel. Just a guess. - |

I try to avoid Federal and will only use them if no other suppliers are available with the exception of the .50 BMG round. We are currently using Wolf Gold series of brass case ammo. We've gone through over 500,000 rounds with zero issues. It burns clean and pretty damn close to 5.56mm spec's even though it's listed as .223 Remington.

Magtech has been the cleanest of all the ammo we used followed closely by Privi Partizan. I try to avoid Federal and will only use them if no other suppliers are available with the exception of the .50 BMG round. We are currently using Wolf Gold series of brass case ammo. We've gone through over 500,000 rounds with zero issues. It burns clean and pretty damn close to 5.56mm spec's even though it's listed as .223 Remington. V/R Ron Why is this? |

I was referring to the future collection of data where he said he would keep us posted. This COULD tell us more about barrel longevity in regards to the manufacture process.

I keep telling you guys, it's not the process that leads to barrel longevity so much as the steel. The engineer at FN specifically stated that it is FN's propriety blend of steel ("machine gun steel") that leads to such a long life in their CHF M249 barrels. They also use a different type of chrome that plates on thicker than that used in the bores of the M4s. |

This is our first "vacation" (just a quick, two-day drive to the beach) since we opened the range and I promised the wife no business so I'll make it quick with a few points.
- we do lose extractors and even lost the extractor on the HK. I don't blame them because we have had extractors break at early round counts and high round counts from the same mfr's. - we've used CHF barrels alongside standard chrome-lined barrels (LMT, J&T, Green Mountain) and though I don't have a true round count, they were put online at about the same time with the same amount of use and one didn't do "better" than the other. Remember, my only concern for accuracy is that it can hit the red center of a target at 15 yards. V/R Ron |

As for barrels, a majority of the barrels are DD and LMT. We have used the Green Mountain 20" pencil barrels for our M16A1's with zero issues.

V/R Ron When using BCG's manufactured by other than DD or LMT what failures did you see. You have mentioned failures of individual bolt components such as cam pins, bolt lugs etc. Other than the shearing of gas key screws(you mentioned gas tube shearing off) what can fail on the bolt carrier itself? I would think these would last indefinitely. Keep the real world experience coming. It is pretty rare to get this type of info on high round count rifles and parts. |

No reason to get a full SR-16 when all you'd need is an upper.
Their SR-15 buffer is 3oz just like a standard carbine buffer. The spring is also standard carbine fodder. |

It's amusing to see all the KAC fanboys come out of the woodwork nervously looking and hoping to find validation!

He stated in his high round count pistol thread the following about Federal and why they use Magtech instead : We use their ammo for several reasons.. honesty, quality and reliability. We've dealt with Federal/ATK over the years and THE MOMENT there is any type of ammo hysteria they will immediately cancel all existing orders and be gracious enough to let us re-order the same ammo at a higher price. Magtech has never pulled that on us and always kept an open order regardless of any sales hype. The ammo has always run clean in our weapons and the ammo has been consistent from lot to lot. Lastly, all of our weapons function on it where others are loaded to light or primers back out and jam the weapons.
The honesty is the biggest concern for me because there's nothing like getting an email from Federal ATK saying that all the ammo that we agreed to sell you two months ago is much more valuable now and we are going back on our word. |

I'd like to see data from 50 yards + Kind of hard to judge loss of accuracy from 15 yards. This is where the lucky-gunner data comes in handy. While there was some slight accuracy degradation (at 50 yards), it held pretty good until the keyholing started. In their case, somewhere between 4000-6000 rounds, with Wolf Steel (steel jacketed bullets). They never hit it with the brass jacketed bullets during those LuckyGunner tests (though did see velocity decline). Note Henderson Defense is not using cheaper steel cased ammo - for fairly obvious reasons I imagine. |

I'd like to see data from 50 yards + Kind of hard to judge loss of accuracy from 15 yards. No kidding. Nothing has been said that takes anything away from the CHF debate. 15 yard accuracy? Lol. You guys really need to read up on all the LMG testing that was done. CHF was found to be insanely more durable. Not apples to apples comparing LMGs to semi auto ARs, but more durable is more durable. Thing is, I'm tired of getting sucked back into this rehash anyway. Frankly, it is literally the exact same four people who speak out against CHF having any benefits. Every time. Just the same four people. Though droves of people speak out in contrast to that small group of four - that includes engineers and machinists as well. At this point, we should probably just let those four live in their bubble. |
