@@ShadetreeArmorer I will get gun smith to look at. Going to get the safety reversed if possible anyway. Not as handy with fireaem modes as you are. :)
@@rmorrissey522 just send him a link to this, removing material from the bolt stop tooth in the right location is the quick and easy way to resolve this.
I bought the AR10 chrome and the cam pin hole for the firing pin was not only drilled 90 degrees out of phase but had an additional 6 degree offset. Enough to shave off the FDE coating inside the brand new upper receiver dry cycling. Needless to say I was planning on a POF roller cam before I bought the bolt. The other issue is the crappy brittle gas key bolts that they don't stake and have a reputation for being highly brittle. Enough so it recommended anyone with one replace them. I found out later after further research(SOTAR) and plan on staking it myself with Michigun screws any way. I am finding that they are behind the times. No specs on materials used, only one extractor, no gas adjustment, terrible gas key problems, no sand cuts or diversion of gasses, PVD's and NiC's are fast becoming the preferred coatings for low cost. There are many companies now doing it better. Sharp's, Surefire, LMT, Bootleg, KAC, KAK , Lantac, Centurion Arms, BCM, DD etc..The roller cam from POF is the only thing I still buy from them. Old man died ain't been the same company since, QC is crap. Ask me how I know? lol
I always thought the modern manufactures took shortening into consideration, that way once it’s shortened/if shortened it’s more or less where it should be
Inherited from my Dad what was originally my grandfather's Colt 1908 Vest Pocket (1919 manufacture). I ran through the six rounds it had in it with no problems. It performed well each time I took it to the range until recently. With .25APC hard to find, I buy what is available but the little pistol has started jamming with almost everything I try in it-- ejecting, but not seating the next round. So, today, I received my spring kit. New magazine spring: 5-3/4" Old magazine spring: 4-7/16" About an inch and a quarter! Obviously feels different to load the magazine, and also when seating the magazine. I look forward to my next range time. Hopefully, it will be less picky about what I feed it.
HOPPE’s #9 went straight into trash and glad I never got the Lucas or any others that underperformed lol, but the MILCOMM was the oddest to hear and see! So thanx for ths!
By making this video, I finally figured out ten-ish years after the fact that Hoppe's 9 was the likely cause of a shotgun malfunction (slow hammer fall) that happened in cold weather. Needless to say, it's never getting used on anything I own ever again.
Well done!! This has to be one of the best disassembly videos on RU-vid. Just one question,, on this particular model there is a flimsy white metal tab/bar in front of the hammer at rest..... it is moulded as part of the frame and I've seen on different forms where this piece gets snapped off for whatever reason but I can't see a reason for it anyway. Too flimsy to be an actual hammer block as its only attached on one side. Would you have any guess as to what it is? Can't see it having any affect on the function of the firearm either,,wether there or not lol....cheers
Glad I found this video. I've wanted a slick-side chrome bolt assembly from Young Manufacturing for a long time. As I'm realizing more, in this post-2020 world, all bets seem to be off when it comes to AR-15 parts quality from even renown brands. Those chrome bolt assemblies aren't cheap at $300, either. One commenter suggested when Young Manufacturing was bought by KE Arms, the latter was probably hard-chroming bolt assemblies that were already nitride-treated and in spec before the chroming. Hard chroming adds thickness to bolt assemblies which would bring appropriately manufactured parts into spec as Young Manufacturing was probably doing before being bought by KE Arms. It looks like KE Arms cut corners and simply slapped hard chroming onto already-in-spec nitrided bolt assemblies.
Absolutely, the M2 balances right under the action and swings easier whereas the Affinity or M3K is front heavy. Depending on what you're used to, one could be preferable to the other. I prefer the M2 for 3-gun type stuff but I could absolutely see arguments for the Affinity/M3K style setup. Most semi-autos are far more front-heavy than the M2 and similar Benelli shotguns.
so it seems that there are issues with the young mfg bcg. there MAY be some tolerence stacking, but it does also seem that there are some QA /QC things not happening as they should. could some of this be due to moving the company and supply chain issues that happened? regardless, this is unfortunate. i was going to go with one of thier BCGs. now either going with a BRT or Lantac bolt. still confused on NiB vs chrome or even DLC
Re: tolerance stacking - this video explains clearly why that isn't a thing. The tolerances of the M4 TDP allow the extremes of sizes to still work together. This is on purpose so you can put them together like legos without hand-fitting, otherwise they'd never be able to mass produce them.
@@ShadetreeArmorer yeah the TDP is for specifically that. i am thinking its more on thier side because something is out of wack, so to speak. like how whatever they check against isnt calibrated right and its not in spec enough so while it works for them, its not within tolerce with others. still gonna go with a different BCG thats not a young mfg.
Watch the video and you'll clearly see why they cannot interchange. There is no mechanism on the M2 hidden under the handguard, as the recoil spring goes into the stock. On the Affinity, there are rails that go under the handguard to engage a recoil spring that sits on the outside of the magazine tube. On top of that, they are different lengths.
I don't lubricate my carry gun at all. I've found that it would contaminate the striker assembly and make the gun malfunction. As little as just having the barrel lubricated too much was enough at the first couple shots to force oil and dirt into the striker causing failures to fire. Springfield XDs .45 acp. I regularly inspect and clean the firearm so corrosion isnt an issue. I carry on my hip so sweat isn't an issue. The firearm functions flawless completely dry so I figured it's better to have reliability over lifespan wear on this one.
Most guns can function dry after breaking in, what they often fail at is functioning dry _and_ dirty. So keeping it clean will go a long way. You might see how it likes a bit of grease on the slide rails and maybe the cam surface of the barrel and locking block. I've used the same syringe of Wilson Combat grease (not the new "II" branded stuff in the squeeze bottle) for 15 years, a dab will do and it doesn't migrate like oil will. Apparently that stuff also went by "ProTec Gun Grease." The brand isn't super important, I just like the syringe with the fine point because I can put it exactly where I want in the smallest amount necessary. Looks like that Wilson/Protec stuff is discontinued but there are others who make similar products, just can't vouch for them. I will say that grease is a bad idea for off-body carry in the cold as the grease will get too viscous and slow things down, but for on-body carry you'll keep it warmed up.
One more thing, I know for Glocks there exists a "maritime spring cup" for the striker for this exact problem, oil or water in the striker channel can slow down the striker enough to cause a malf. You might see if similar solutions exist for the XD. I've never needed them on my Glocks.
So about 4 years ago, I bought NM Young BCG for a 20" SPR I had been collecting parts for , for 3-4 years prior. After loooong research and about a years wait for them to come back in stock, I got mine. I knew that Young used inferior screws on the carrier key, so I ordered some OCKS screws and had a 'smith install & re-stake them. I sent the bolt itself to an extremely well know barrel maker for headspacing to a barrel ordered. The owner called me and said he could not headspace that bolt to any barrel they currently had in the shop because "it is too small". I was upset, to say the least. This man then said he didnt want me to have to wait to sort this out- so he GAVE-FREE...to me a new unfired BCM bolt, which is in the rifle now. Due to the extra size & weight of the NM Carrier, Ive had to use a stronger recoil spring in the rifle to get 100% functioning. Had I known all this I would have went a different route.
This is excellent. A lot of talk on this very subject, without real data. This is real data, showing that the loaded springs compress (shorten) over time.
mags are really meant to be disposable, consumable items. i personally keep all my mags loaded, so these "tools" are always ready to go if an emergency need arises. even if keeping them loaded for years will reduce their service life and service cycle, then so be it, replace them periodically as intended and pull new ones from your stockpile. i don't understand why some people want to "baby" their mags, an empty mag simply serves no purpose, then why even have them around? it's like "babying" your car by parking it on the drive way with gas tank empty, and only fuel it up before you go for a drive. doesn't make any logical sense.
Tolerance stacking is such an incredibly stupid reply. It shows how little they know about the platform and how little care they operate their company with. Someone needs to tell that guy that this isn’t the 1700’s anymore with cottage industry. I should be able to take any AR-15 BCG and fit it any Upper. If it doesn’t, one of the two is messed up. Either your shit is in Spec or it’s garbage.
So can you just use plane language elastic non elastic just say yes it does or no it doesn’t do loading and unloading wears out the spring ? So shooting a lot wears out the spring so do you leave it loaded or not
I think you should atleast let the company know so they can make adjustments to their machining procedures to keep things within the specification window of the parts they make. I always atleast give these companies the benefit of the doubt that they will fix issues for future parts they machine if you tell them the issues. Unless they are another company purchased by Bob Beck that he ruins then i just stay clear of them. I have been runing Cyptek Coating's BCG's with great results
I’ve always loaded stiff magazines that are a little stiff getting the last few rounds in . And it’s always helped . I stop leaving them loaded when I find they aren’t as stiff anymore .
People complain about them frequently online, but I've never had an issue with them. I think it's a known problem that you should only use brass cased or nickel plated ammo in them. Aluminum and steel seem to drag too much. I only use brass cased ammo, and I've used those magazines to shoot competitions quite a bit and never had a failure that I would attribute to them or had one break.
I suspect that the original Young MFG machined their bcg's at reduced dimensions to allow the hard chrome lining to bring it up to dimensional spec, but when KE started offering nitrided bcg's they just machined all bcg's to actual finish dimensional specs without any consideration of the added thickness of the chrome lining.
I'm in Idaho and have been using the Lucas for years problem free but I don't run my guns dripping wet either and during the summer I've found that it doesn't burn off as fast on my A/R. I've often thought that they're probably just marketing/rebranding 2 stroke gas mix as gun oil Lol... Great video!
The larger problem I see with this company is that he knowingly turned around and resold a bad part to likely an unsuspecting customer that's going to prematurely wear out his A/R or worse destroy the A/R and possibly cause bodily injury and or death! A company that will do that instead of just throwing a $200 part in the garbage tells me everything I need to know, not to mention the liability they face as a company! And you put all the evidence a victim needs on RU-vid.
