survivalshop Posted December 9, 2014 Report Posted December 9, 2014 OK so I ended up buying a second BCG from Fulton armory for a future build. You can see from my earlier post the original one I got has the traditional cotter pin in it. The new BCG I got has a completely different pin in it. The best way to describe it is it has a flat button like face and sits deep inside the carrier. Never seen that style pin before. What's the pros/cons of it? The flat head pin with the slit at the end , is what comes in most 308 BCG 's . Its the original pin design, I believe. I'm not sure when the M16 Family of Firing pin retaining pin changed , something to look up or some brainiac here may know already .

Rsquared Posted December 10, 2014 Report Posted December 10, 2014 The original design is what Armalite still uses. It's the cotter pin type design. And no.......I'm not being biased. <laughs>

Yes, the original firing pin retaining pin had a flat head and looked more like a golf tee. It was changed to the cotter pin as part of cost reduction (IIRC same time they went from full chromed carriers to just the inside).
BadBoyBilly Posted December 10, 2014 Report Posted December 10, 2014 OK thanks guys. Never saw one designed like that before.
98Z5V Posted December 12, 2014 Report Posted December 12, 2014 AR-15s/M-16s/M-4 variants aren't like that. They're the cotter-pin-type. The .308 ARs started out with the split-pin setup you've now seen. It was all about manufacturing money, like Fark stated.
mrrogers1 Posted January 15, 2015 Report Posted January 15, 2015 (edited) I just got both of my Aero Ni-Bor complete BCG and I really don't have much to compare to but... From what I do have, pictures and first hand use/handling of 556 Ni-Bor groups, the finish is weird. It doesn't feel OR look quite as nice as the groups we see pictured (earlier in this post) or ones I've handled. Not sure if it's just a different type of application of the coating or maybe not as much finishing work done to the parts on Aero's part. I'm going to upload pics in a minute and you guys take a look and let me know what you guys think. I'm not dogging the product or mfg, it's just not what I expected from even their images, when I opened the box. Edited January 15, 2015 by mrrogers1
BadBoyBilly Posted January 15, 2015 Report Posted January 15, 2015 Yea just going by looks alone, the finish from Fulton Armory seems better. As far as Aero's finishes go, I have one of their AR15 receivers in FDE. The coating EASILY comes off. Probably one of the least durable coating on a receiver I've had to date.

I have quite a bit of Aero hardware, started back when they were smaller and the old logo existed (I still like the old one) but sadly, what I got looks nothing like what they advertise... http://aeroprecisionusa.com/aspx/store/productdetail.aspx?pid=340 I don't want to be a mitch about it either, maybe it'll function just fine and it "is" slicker than phosphate but I'm kind of scatching my head here.

washguy Posted January 15, 2015 Report Posted January 15, 2015 If anyone needs a nickle boron bcg...ive got a black ops that I ordered back in july and it just came in 2 weeks ago...I dont need it ..these are sweet!....200 plus shipping....box never opened :) Wash
Matt.Cross Posted January 15, 2015 Report Posted January 15, 2015 I like Aero products, but I gotta admit that doesn't look so great. Have you contacted them about it?
mrrogers1 Posted January 15, 2015 Report Posted January 15, 2015 I like Aero products, but I gotta admit that doesn't look so great. Have you contacted them about it? Nope, I wanted to post and get just a little feedback before doing that. I only have their advertised picture, other vendors pictures to go by. Calling and being like "hey, this doesn't look like the picture" probably wouldn't get me too far. They just started selling these, I pre-ordered and I know there aren't many out in the wild yet... Maybe a got TWO lemon's that dodged QC. :)
BadBoyBilly Posted January 15, 2015 Report Posted January 15, 2015 Yea it will probably work fine but what they advertise should be what it looks like. Easy on the Photoshopping!
BadBoyBilly Posted January 15, 2015 Report Posted January 15, 2015 I seriously thought about buying one back when they had the pre-order available. I said to myself that the first batch is probably going to have some "kinks" in it so let a couple rounds of batches go through and see some reviews online before considering. Sucks that you got a product you are not 100% satisfied with. Wouldn't hurt to give them a call. I know Aero's customer service is top notch. You never know what they will say if you don't call them.
392heminut Posted January 15, 2015 Report Posted January 15, 2015 (edited) All the NiB BCG's I've seen were silver. That doesn't look silver at all. Is there a darker shade of NiB out there? <dontknow> Edited January 15, 2015 by 392heminut
mineralman55 Posted January 15, 2015 Report Posted January 15, 2015 All the NiB BCG's I've seen were silver. That doesn't look silver at all. Is there a darker shade of NiB out there? <dontknow> Yes, after they are fired a few hundred rounds. I cannot get the dark gray stain off the NiB BCG. Works great, just doesn't clean up.
washguy Posted January 16, 2015 Report Posted January 16, 2015 (edited) Yes, after they are fired a few hundred rounds. I cannot get the dark gray stain off the NiB BCG. Works great, just doesn't clean up. all the ones ive seen or used are golden in color and they dont turn gray...and they are slicker than a cat's azz :) Wash ooops I was wrong on color...not golden....a bronze/gray color Edited January 16, 2015 by washguy
mrrogers1 Posted January 16, 2015 Report Posted January 16, 2015 I'm used to what LWRCi uses which is, indeed, slicker than snot! It's crazy how smooth it is and this is not like that. I may post in a vendor thread they have going once I figure out if everyone's looks like this. I probably wouldn't have ordered if it looked like this in the add, because all the other NiBor offerings do look smooth, bright and very friction resistant.
planeflyer21 Posted January 16, 2015 Report Posted January 16, 2015 Yes, after they are fired a few hundred rounds. I cannot get the dark gray stain off the NiB BCG. Works great, just doesn't clean up. Yup...same experience here with the BCG on the PPPE (Pink Purple People Eater). Looks very close to a tarnished silver color.
mrrogers1 Posted January 16, 2015 Report Posted January 16, 2015 Yup...same experience here with the BCG on the PPPE (Pink Purple People Eater). Looks very close to a tarnished silver color. So yours looks like the brand new ones I posted a pic of OR are you saying you had shiny new like other vendors (posted earlier this thread or like the Aero ad) and it turned that way after a few hundred rounds?
washguy Posted January 16, 2015 Report Posted January 16, 2015 hmmmm... sumthins not right..I put together a 308 using the shadow ops bcg for my best friend and it looks unused after lots of rounds....wipes clean with a tissue lol :) Wash
guruofhotrod Posted January 16, 2015 Report Posted January 16, 2015 Those pics don't look like any NiB that I've ever seen - looks more like the Nitride finish SAA uses on this model: http://www.surplusammo.com/saa-m16-complete-nitride-bolt-carrier-group-223-5-56/ Incidentally I'm pretty certain that Aero makes the house brand uppers and lowers for SAA and may also make this BCG.

It's definitely brighter than that, more silver/Chrome than black BUT it does not look like any NiBor I'd seen either, hence the posting. Just making sure I'm not going crazy over here... :)
98Z5V Posted January 16, 2015 Report Posted January 16, 2015 Incidentally I'm pretty certain that Aero makes the house brand uppers and lowers for SAA and may also make this BCG. AP does make SAA's stuff for them - they're right across I-5 from each other. <thumbsup>
