What can I do to bolster my confidence in the following uppers? If it means buying new uppers, then I'm cool with the hard right. - One has the cardinal and the other has the keyhole marking. - One has a Wilson (I was told) heavy barrel, the other a BM (clearly marked). - I've put 160 rounds through one and 38 through the other with 0 problems. - If it matters, these are pistol uppers, 11.5 & 14.5. - Both are flat tops with "T" markings in white. Should I send them to ADCO for a rebuild with a new receiver? Should I get Bravo Co BCG's and call it good (is the BCG more important than the upper receiver)? If it's not reliable, it's not worth having. If I can make these reliable then I will. If I need to sell them at a loss and buy two others, I can live with that. I appreciate any help. |
in most aspects, "yes", the BCG (specifically, the bolt) will be one of the most imp. aspcts in reliability imo, you havent run enough rnds though her to even begin to get a count on possible reliability...run at least a few hundred rnds of varying brands, and go from there FWIW: i'll agree, you are worrying too much about the wrong things at this point... |
You could buy the MOACKS AR 15 Carrier Key Staker and properly stake your gas key if you really want some peace of mind. Moacks If it were me, I would buy more ammo and shoot my uppers until they actually experienced a malfunction. Only then would I worry about about what to do next.

If it is running okay then leave it alone! OLD type carriers are just as good as the new FA carriers As far as running My RACK GRADE Bushmasters car/Rifle ran and never jammed and they used the older stlye carriers IF IT AINT BROKE DONT FIX carry spare parts/ BF CLP FOR SHTF CARBINE/AR I RUN 1000rds threw it if theres 0 problems IM HAPPY thats my take of 26yrs of shooting AR15`s |
