Question 1: Assume ownership of multiple ARs. Assume further that some carrier key screws have not been properly staked, but appear not to have loosened. Is it correct to then assume that the keys should be properly (MOACKS) re-staked but need not first be loosened and re-torqued before re-staking?
Question 2: Same as Q1, but assume screws appear to have loosened. They should then be re-torqued prior to re-staking, correct?
OK, here’s the dumb one. Question 3: Why is it that many/most uppers are priced minus CH and BCG? Just to keep the price low (which would seem pointless as you still have to buy a CH and BCG) or for some other reason?
ideally, you’ll retorque the screws prior to staking if there’s any question at all.
as far as uppers without BCGs, your guess is as good as anyone’s. a lot of guys order uppers without BCGs to get 'em quicker, knowing that right now people will pay complete upper price for an upper without BCG, handguards, charging handle, etc. pretty gay.
Always check to make sure they are properly torqued and then stake.
The reason the uppers dont come with the BCG or CH in many cases is you are buying ala carte and not a complete rifle. Its better to have a choice of what type of BCG you want for the upper as you are piecing it together and not forced to take what they think you should have.
Because that would be to much like right. Then they (sellers) could not sale the BCG elseware for $200 plus. You can see on the EE that parting out uppers, and complete rifles even are bring several hundred more than the complete rife would sale for. Thats why you see this.
There was a guy that split up a complete Noveske rifle the other day. It had the mark on the upper and lower. Kinda hurts to see that, but oh well.
You would have to asj the individual selling the used upper for that one. Some and they shouldnt run the same bolt in multiple uppers instead of buying another for each.
