This poll is for those who have bought the PSA M-16 BCG's with the SKU number 8784, And they are concerned with all the questions that now surround the BCG's.
Do you think that PSA sould allow those who are not happy to return them?
Should those that bought them just take this as a learning experience?
My concerns on waiting is after so many days PSA will not warrenty them, They break at a bad time, There are problems with them and I don't know about it because Im not here monitoring AR-15.com for problems with these BCG's, As stated already mine may not see use for over a year or more.
If these BCG's are supposed to be mil spec, does anyone think price aside that the military would use these BCG's or not with the issues that have been brought up
about them? I see several issues that make these bcg's non mil spec.

My BCG's were bought for SHTF, Future use, And backups, And I may not need them for a year or more and I would hate to find out then or the hardway that these BCG's in question were
promblematic and the warrenty was expired. I want to nip this on the bud now, not later.
The problems that have been pointed out are:
The gas key is questionable as to how its made and the hardness of it.
The bolts that hold the gas key to the carrier are Taiwan made.
The Torque on the gas key bolts are not correct.
The staking job is not what I and others see as a quaity staking job.
No sealant between the gas key and carrier.
Neither screw was torqued to spec. The front screw was 37 inch pounds while the rear screw was 79 inch pounds.


Here is what another vender said.
http://www.ar15.com/forums/t_3_118/611732_Got_my_PSA_BCG_today__Pics.html&page=4#i6028733

- No Loctite visible any where.

- No Permatex Aviation sealant visible any where.

- Carrier key was not perfectly flat on the bottom surface which mates to the carrier.

- Carrier key screw holes are oversize.

- Staking wasn't very effective.

- Carrier key is junk quality

Please refrain comments about other PSA products that you have, this is for PSA SKU# 8784 M-16 Bolt carrier group only.

ACCORDING to the REP, it was just a few bolts/BCG's.  His words not mine

I purchased one through another user on the EE that seems to have the same issues as noted.  I can honestly say I'm not too concerned.  Obviously I'll find out if I'm wrong if something bad happens, but I highly doubt it will.

I've done some research and can't seem to find any documented incidents of issues with MIM gas keys.

Also on the Taiwanese screws, I can definitely say I'm not too concerned.  The gun it's going in isn't a SD/HD rifle so no worries about reliability there, and if they were to fail, I don't see it causing any catastrophic damage short of the gun going down for the day.

All in all we'll see where it goes, the gun probably won't be shot for a while, but once it does I'll make sure to post some results.

I'm guessing red loctite should be used, it is some strong stuff.  I used to use it on paintball air fittings and had to heat the crap out of it and put an insane amount of muscle into breaking the seal.

Have you voiced your concerns to PSA in a diplomatic manner? It helps to be nice about it and patient. I treat them with respect, voice any legitimate concerns, and they handle it. It doesn't have to be more complex or difficult than that.

Incorrect.  The red Loctite will melt after around 100 rounds.

Why wouldn't you just stake the fastener heads?

I would stake it, I've just never had to attach a the key before and heard recently loctite should be used.  I appreciate the feedback, I will leave the red loctite out of the equation.  Just in case, is there a more appropriate grade of loctite to use?  I've only had experience with red & blue, not sure what is suggested for this application.

However, who can afford to shoot more than 100 rounds these days anyway?

I think it's in regard to Spike's Tactical in one of the threads mentioning that after disassembling one of the PSA carriers, he didn't notice any visible Loctite anywhere.  Gave people the impression it should be there.

Here is mine from that sku 8784

http://i210.photobucket.com/albums/bb315/coppertop_pics/100_0102.jpg

Bad staking and questionable key. Two days after my first email to PSA, which asked if i could either send the carrier in for replacement of the key or send the entire BCG back for a refund, I get no reply from them. I do get a notice from UPS that a label has been generated for a return to PSA. So i send a second email asking if I just need to return the carrier or the entire BCG. Going on the third day and no reply. I have IM'd the rep that posts in their industry forum yesterday, no reply. For a BCG damn near the price of BravoCompany this is kinda sad.... I've had another forum member offer to replace the key and only pay postage which was genuinely very nice but I'd like to see PSA fix their own issues.

Bad staking

People are about 1000% too wrapped around the axle on extreme staking.  We're only a short step away from demanding that the screws be spot welded.

IIRC Taiwan had the TDP for the M16, as they manufactured it there along with some  derivatives.  Is the claim that the items are somehow substandard, or just that they are made in Taiwan?

I have one of these, PSA has stated if I have issues I can contact them and since I'd used the bolt before it became a issue here online. I'm not worried about the staking, it's about the same as my Colt 6920 bolt so I can use it.

I intended to get a BCM BCG for the build this is in anyway so when that happens if it's a concern I've ordered a BCM gas key and bolts, I'll replace that when I have the BCM bolt and either use this as a spare or in another build

Correct this is what the Spikes Tactical guy said about the BCG's


To be completely honest with you guys, the questionable carrier key concerns me way less than the assembly procedure used to attach the carrier key to the carrier. The good news is that the carrier itself actually looked pretty decent. It's good to go now with the new key in place and it's on the way back to the OP.

Here's what I found,

- Neither screw was torqued to spec. The front screw was 37 inch pounds while the rear screw was 79 inch pounds.

- No Loctite visible any where.

- No Permatex Aviation sealant visible any where.

- Carrier key was not perfectly flat on the bottom surface which mates to the carrier.

- Carrier key screw holes are oversize.

- Staking wasn't very effective.

- Carrier key is junk quality.


So if a person who is well educated on BCG's says this what am I to do but listen and be concerned that I have substandard BCG.
These bcg's were advertised as mil spec. However now I doubt the military would ever even consider these for use and of course I'm putting price aside
And speaking strictly on quality.
