Looks like Rainier has some F-1 Firearms Rose Gold ones in stock. If they are good? Not sure. $400 though, wow.

http://arpartsfinder.com/instock/bcg/ and you can put 308 or 7.62 in for product search.

True and gotta have a BCG. I have seen some around. I don't know how good Rubber City Armory are (cause I'm a 308 n00b) but I think they had gotten some of those in at Primary Arms a day or two ago.

It's probably do-able but I wasn't that lucky/patient parts shopping. There are some pretty good prices at some places for Ballistic Advantage barrels when they pop up in stock. Granite Ridge Outfitters and Right To Bear for example. I've also seen em listed at Moriarti Armaments, Rainier Arms, and Primary Arms. Granite Ridge has a "MOA" discount code and Right To Bear seems to offer free shipping on the whole order with at least some Ballistic Advantage barrels (maybe all? not sure). I am a noob with 308 AR's though, no connections and not a lot of experience with many of the vendors either. So I'm learning my way around aside from the ones I've been buying other stuff from. Not sure what you are looking to build but these are a couple things that *might* be of interest: KAK Industry has KAK-branded UTG Pro Super-Slim 15" (14.65") octagon shaped (and full pic rail on top) M-LOK handguards from KAK industry for $185. (SKU MTU026SSMB-KAK) You might be able to find a UTG MTU026SSMB cheaper elsewhere, they list on Leapers site for $139 and they have a list of dealers, but KAK had (and still HAS) these in stock. Couldn't find one in stock anywhere else on Leapers' list of dealers but you might have better luck, this was a few weeks ago. Seems like a good solid rail and it is definitely slim. Will use this on the 18" barrel build in the hopper. Another handguard that seemed nice and wasn't as expensive as SLR 308 handguards are the Samson SXS Lightweight, you might like that. They have another series that are in the $185 range also (SXS 762 series), pretty similar to the UTG. https://www.samson-mfg.com/308-ar10.html There may be some signficantly less expensive handguard options but I had a heck of a time finding anything in stock I was interested in -- always seemed to strike out on the high vs. low profile, M-LOK vs Keymod, length, etc. I was looking for. (I was looking for DPMS High M-LOK). LPK's I got at KAK Industry too. Someone may disagree and again I am a noob to 308 AR's so take anything I say with a grain of salt, I was relying on reviews which seem to be pretty darn good overall on the quality of KAK LPK's. But they seem to cost less than some of the more famous brands. I dunno.

Talked to LANTAC and sent some pictures. They said send it back and sent me a return label, it got there today. They are pretty close by. Will work with the other BCG in meantime, GO and NO-GO were just fine (GO went, NO-GO didn't). Hoping for straight-out replacement quick. They made it sound that way when I talked to them so I decided to let them. Thanks for the answers, suggestions, etc. I will get some spare parts for the rainy days. 98Z5V I understand the "just shoot it". If they had not given me good impression of just replacing it I probably would have. And my best 308 handloads were with once-fired Lake City brass I stumbled across by accident from a metals recycler so we are definitely on same page about that. 🙂

Thanks for those brand and site recommendations. I've added them to the parts bookmarks!

PS: the reason the FP was "stuck" in position in the 2nd BCG was simply due to rotational position of bolt+cam pin. 🙂

opened up 2nd BCG, it is perfect. Firing pin is pristine. No burr up by base of gas key either. Haven't disassembled bolt to check headspace with 2nd barrel yet but will do so. I suspect it will be just fine. Firing pin is one of only parts I don't see listed in stock on their site but I will talk to them tomorrow.

Thanks for the additional replies. "in the multitude of counsel there is safety..." Really do appreciate it. I admit to being both a perfectionist and a noob to 308 AR's (and even AR's in general, to a lesser degree). After sleeping overnight and thinking about it fresh this morning, I realized what some have already said (and what I was also thinking as a factor), that I should be happy I found 2 BCG's and try to work with them. I'll contact Lantac tomorrow to ask about the firing pin and whether they believe it could indicate any type of problem with that bolt or the other thing or two I see and go from there. I imagine they would probably replace the firing pin for me due to condition I received it in straight out of the package. I will also open up the 2nd BCG and give it a good checkout. @mtrmn that is what I was thinking also as another possibility as to why the pin is sticking out of other bolt and won't tap out with some light taps of the package, maybe just some oil/grease. Assuming my concerns are put to rest, I will also ask them what other firing pins are compatible with this one and/or see about buying a couple spares and some other maint-related spare parts like extractor and ejector pins, springs etc.. All in all I decided that it really does make th e most sense to try to keep these BCG's, which are probably going to be just fine and high quality, if I can at all. Because times are strange... Gentlemen thank you. I did also check barrel chamber and bolt fit with this bolt + GO and NO-GO gauges and all is well. So I'm hoping for the best, ready to continue building first upper. Thanks again.

Yep mtrmn, exactly. After initial research trying to find out who made the high quality BCG's I felt exceptionally lucky or just happened to be looking at exactly the right time to find those 2 I did find. There was almost nothing I was looking for in stock, but then suddenly pretty much everything came together at once for the first one, then the second a few days later. And not many BCG's out there again now. I don't want to have to send these back if I don't need to when I don't know where I can get a couple more BCG's. Good advice on the pin. I will want to have spares handy anyway. Had not seen your message yet as I was finishing up the one I just posted. But I was thinking same thing, talk to Lantac and see what they have to say before banging any gavels. I may never see any kind of wear or impact like this firing pin has on it in normal use.

Thanks jtallen83, I thought about that too. Wouldn't stuff made to perform under this kind of pressure take it without damage? Anyway, I will talk to LANTAC, hopefully on Monday, before making any decisions and go from there. I'm not really too keen on keeping things that have damage or defects right out of the box if that can't be rectified. If this came up 6 months from now after a lot of rounds downrange I would look at it a little differently. I also know we're in kind of strange times. Thanks though - really. Wish I had more experience under my belt here. Looks like I will have come by it honestly (painfully and grey hairs) whenever it is that I get there... but I usually do. 🙂

Thanks for the replies. I may just be being paranoid about the ones I have. Not sure yet.

Hi Viper -- welcome! I am new here, nobody special but it wasn't that long ago I had posted my introduction. Great crowd here. Was born in TN once upon a time, in TX now - so welcome from Texas! Tack14

@Lonewolf McQuade maybe. (and thanks for replying) -- but I don't understand, the more i think about it and slide that firing pin around in the bolt, how it would be normal to get such digs into the fiiring pin. I can believe to a point that it may have been shock of package in transit with not enough packing materials making the pin slam laterally against some surface from shock inside the firing pin passage of the bolt. But when much at all of an angle is on the pin towards the extractor, the firing pin usually catches a bit. and the more I slide the pin through there the more it rubs on the pin (I know, captain obvious...) I'm not an expert on AR bolts, so I may just be overthinking all of this. And the pictures I posted probably weren't that great. Is it normal to get big digs/scrapes in your firing pin before you've even opened the package or would that be more suggestive /indicative to you of something not quite right in the passage the pin has to travel through?, like an edge sharp enough to capture the firing pin long enough to dig into it or make it stick? Maybe I'm just really over-analyzing this. Definitely possible. Maybe all of this IS normal and I'm worrying about nothing. But if I spend $20 or more on a brand-name 308 firing pin (and hope $MFGR will at least offer to replace the brand new damaged one I got from the package) and it turns out that replacement one gets eaten up also, by the time I have confirmation that my bolt on this BCG eats firing pins I will be past my return window and stuck with it, short of dealing with the manufacturer. That's what I"m worried about, primarily. The other one of these BCG's I have still in sealed pkg, the firing pin is sticking out of the bolt and may (I know, may != is) be stuck that way because that bolt has the same sharp edge that shouldn't be there too, and captured that firing pin. I just know my chances are better of full refund and no hassles if I don't open that package. It's frustrating. Sorry to spill all this noob foolishness of "I just don't have enough experience to know". Seeing these kind of digs and gouges in the pin scares me, that's all. If you guys are saying its normal dont sweat it, who cares if the pin gets some chunks/scrapes out of the taper behind what sticks through the bolt face, it shouldn't ever fly into the primer with more than a degree or three of til anyway in actual use (firing, hammer strike), then OK. Then I guess if I can get past the burr on the "driver's side" edge of the "ledge" the gas key bolts to maybe I should just settle for what I have and be glad to have the BCG's as we head into very questionable supply chain times.. @shooterrex thank you for replying also -- I really just got started building the first upper. I was going to try the bolt with the barrel and GO + NO-GO gauges to verify headspace.

Gosh sorry, the other thing specs wise is I am not looking for "low mass" or anyting like that. Just regular full-mass. Already bought the HeavyBuffers buffers and recommended springs to go with them based on full mass.

Yeesh, I just signed up here and already I feel like I have used up the n00b points. I am looking for a high-quality, no-BS brand of 308 BCG for 2 LR-308/DPMS "High" builds. I'd really like to score a couple Nib-X but, would settle for Nitrided or some other highly corrosion-resistant finish. Brands that in April 2021, people who have been around this block would not bat an eye to recommend buying 2 of and being 100% confident I would get 2 good ones. The other thing I really need a recommendation on is a vendor. Who would you recommend above the others out there to place an appropriate level of care/attention to packing the box properly -- not just throwing a high-end expensive BCG into a box with a few air pillows or a crumple of paper (and MAYBE a hail mary muttered if I'm lucky) that it gets here intact? (I know "DPMS high profile" has nothing to do with the BCG, just trying to further distinguish that I am not looking for an AR10 BCG, but rather for 2 for *DPMS/LR-308* builds) I don't want to bad mouth anyone so I won't. But let's just say I have not had good luck buying BCG's the last few weeks. I already have a green light to return one that has a very chewed up firing pin and a nasty burr under the gas key right out of the package that, on general principle, means it will NEVER see the inside of my brand new upper or BAD charging handle -- and the other place has a 30 day return policy I am still inside of. I haven't even opened the stapled-shut package on that one yet, but the firing pin on that BCG is stuck protruding from its bolt face, still inside the package, and I can't get it to tap loose. So my gut is telling me after what I saw disassembling the bolt on the first one "EJECT! EJECT! EJECT!" -- I am probably going to be best off if I don't open that package rather than take a chance... Thanks for any and all recommendations. Also please feel free to poke fun at me and so forth. I'm pretty used to it...

aaannnnnnnnnd the 2nd brand new BCG, same make/model but different vendor, I haven't even pulled the staples holding the clamshell together yet, has the firing pin stuck sticking out of the bolt face even when holding ass end down and tapping gently. (I would expect the pin to fall back down). This vendor just dropped the BCG in a box with one wad of paper and handed it to Fedex. So I imagine this firing pin will also be chewed up all to hell. I have probably had this one too long to be able to return it. I guess I'll start a new thread asking for a brand recommendation, AND a vendor recommendation. I need to find a vendor who knows how to pack high-end, expensive, and often heavy parts that are damn hard to find in stock anywhere into a box properly so you don't waste time, money (don't forget about those shipping fees you paid...) monkeying around with returns and so forth.

Hope this works out for you rockyboy. Concerns like these are why I am very skittish about messing with the firing pin I got on BCG#1 I opened up or the rest of the BCG either.

Dang - that is awesome. My 300 mag needs a little work.

I have one more of these BCG's I bought for 2nd 308 AR. Will open that one up and look that one over in the morning. I think this one will be going back.

I dunno.. the more I think about this, the more I am not liking what I am seeing.

Wow, yeah pretty sure that is the one I saw someone using in a video. Thanks 98Z5V.

Here's a pic with the extractor off. I haven't had too many AR bolts apart but this looks fairly different from the bolt on my (5.56) AR. Sliding the firing pin in and out of there with a little "tilt", I can feel the pin catching against what would be the "bottom corner" of what would be the "cutaway" section under the extractor, if that makes sense. And looking how the pin slides through I could see this maybe being the culprit. You can feel it if that pin has any "tilt" to it coming through the passage. Of course, how much til would you normally have if all is good/normal? But something is not quite right.

the firing pin is moving pretty freely through there, occasionally hangs a little when tilting it moving finger away to let it slide out/fall but not much. i can see in the channel (a bit like looking down a bore) but will probably have to try a piece of wire to see if it is hitting something sharp. Actually I need to get the extractor and ejector off anyway, looks like I should be able to see more once I get the extractor out. there is a section up closer to the bolt face that is "open" around the extractor.

sorry, I should have clarified. it drags bad running over my thumb, but will try putting it back into the bolt and see. Just hideous, lol. After 1500 rounds through my M14 that firing pin was still smooth. 🙂 I think this one just got slammed around alot in shipment. 😞
