I don't know why firearm manufacturers aren't lining up to supply you with firearms (for free) to put on the line and test. But then again maybe some don't want to know how their guns don't stack up against others.
Great thread Ron! |

One of the best threads on this site. I have read over this thread several times. Thank you for sharing your experiences.

Ron,
I haven’t read all 36 pages, only about 7. Great information and reads. Got a question that might have already been asked. Sounds like your running tons of FA setups. How are say commercial SA Colts holding up to your FA M4s? I know FA fire is harder than SA. Just curious if your experience significantly less malfunctions and wear with SA Carbines. Awesome thread! |

Have you used any of the Aero M4E1 enhanced uppers? Could a upper receiver be designed to eliminate that failure? Sorry if it was previously asked. Long thread. |

@HendersonDefense
Great thread, I always come back to it to get more data. Do you have any further input on nitride treated barrels? I know you were saying that the CL barrels last twice as long as the nitride barrels, how much longer do the nitride barrels last compared to unlined? Might not be kosher to talk about specific manufacturers, but wondering if you have any Ballistic Advantage or Faxon barrels on your line and how well they've done. Further upthread you also mentioned eliminating egging out of FCG holes on 9mm subguns by converting to A5 stocks, rifle springs, and H3 buffers. By A5 stocks, were you referring to the A5 length extensions? Great thread, though I'm kind of bummed about pmags not holding up as well as USGI...since I already have a pile of pmags . Time to get some Brownells mags... |

My staff set these two Colt semi-auto receivers to the side after discovering cracks along the left side of the magazine well. This is a first for us and we haven't seen this on any other receiver. I don't know what would cause these cracks but one is being ran in 9mm and the other is being ran with 5.56/.223 ammunition.

Looks like it is at the offset in the magwell. Weakest spot and the block looks to have an edge/offset that could hit it if it banged back and forth. Same side as the ejector maybe the block banging back and forth on cycle. I would guess both were used at some point with a 9mm block in them.
May be partly why Colt pinned the block. 9MM must be pretty rough on cycling from all the ramping, heavy buffers, and reports of pin hole wear that people have mentioned over the years. May be something as simple as a broach weakened it when the magwell was done and it was doomed to fail at some point. Could be from too many right handed people shooting it. Pushing against the forearm to the right putting the weakest spot under tension and cracking it. The other side would be under compression so no crack. . Maybe mark a new one for lefties only and see if it cracks on the other side. |

I'm guessing it trumps anything the military has out. Even the random old pic of a hydromatic lower still in service probably doesn't have the round count of these. |

View Quote If the rear pin is at the low end of the tolerance and the front pin is at the high end of the tolerance the front will pin will take the majority of the force. Until the time that the front tolerance opens up due to wear. Reverse this scenario and the opposite would be true. |

No one owns the air!
|
Meh. If a person can afford the amount of rounds it took to crack the lower... You can easily afford to replace the lower.
|
|
Trust me, its more better...
|
First thing I also noticed were the cracks were almost exactly in the same spot, and almost shaped the same. That lead me to immediately think bad batch of receivers. (Also already noted by someone) So my question is how close are the serial numbers of the lowers?
|
|
|
Duh. I just relooked at pics and the serial numbers are clearly visible. They ARE pretty close.

Ron, I again ask whether or not you have experimented with Cryo-Treated parts. I have no connection whatsoever with any Cryo-treating providers, although I have had some barrels cryo-treated, to good effect.
The reduced stringing of thin barrels after cryo-treating might not be of much interest to you, in your business environment, but cryo-treating other parts that are prone to failure might be of use to you, financially. In any event, cryo-treating some problematic parts, and then reporting on how such parts fared compared to non-cryo-treated parts might be of very broad interest. I have been a customer of firms offering cryo-treating, and am a firm believer on its' benefits in reducing heat stringing on very thin barrels. I'm no expert on this subject, except for what I've personally experienced--and all to the good. Whether or not cryo-treating fits into your business plan remains to be seen. May I suggest that you investigate cryo-treating of selected parts, do a test, and report back? Disclaimer: No financial interest. |

V/R Ron Primarily, I was thinking of parts that frequently broke under use, and whose cost per item/ number of items used might make the possible benefits of cryo-treating such parts economically viable. Naturally, such parts will vary with the firearm. For example, an expensive part that was prone to failure would be an obvious candidate. OTOH, inexpensive parts, consumed by the dozens, might also make sense. I have pointedly not suggested any particular cryo-treatment provider, lest I be caled a shill for same. A simple search for "cryo-treatment" providers will give you some hits that you might find interesting, and whom you can contact. A discussion with them will give you a better idea on which, if any, parts might benefit from cryo-treatment. At least some of the cryo-treatment providers are FFLs, and are familiar with the procedures for handling such items. I realize you have lots to do, and little time to spare. This is just a suggestion for experimentation and hopefully it might be of some use to your business. Submitted for consideration. ETA: FWIW, I am sending off 3 barrels for cryo-treating in a few days. So, I am paying with my own money for a service I believe has value to me. Whether or not such a service makes sense for your business is up to you to investigate. I hope this post will be of value to you and your business, at least in some small way. Best of luck to you in any event. |

Henderson,
This question is about lubrication. You stated previously how your company uses Slip2000, Mil-Comm and Lucas. Do you and your armorers recommend grease or oil and have you guys noticed a difference in grease vs oil in its longevity and protection? Which is superior at reducing wear and can go longer between re-lubing? Also, has your company ever tried Lubriplate grease? It's extremely cheap to buy in bulk, aluminum based grease for the food industry that's non-toxic but also works great on guns according to Grant Cunningham. |
