What is the difference between this one and SKU 7791928?
Sean F on May 22, 2018
BEST ANSWER: I don't believe there is any difference at all it is the same product. But since it is a daily deal they use a different SKU (516445123) from the regular SKU (7791928).

Got a lemon
Got this for a pistol build. Coating is too thick in the gas key. One round and the gas tube was damaged. The pistol locked up. Changed gas tube and used another bcg, worked fine. This bcg is tight and/or binds up four different AR’s.

Good value for $89.00 and free shipping. Nickel Boron was smooth as glass.

Good price ..little rough around the edges
I gave this NB carrier a try for $99.00 and free shipping. I am not as impressed with this carrier as I have been with PSA phosphate and nitride finished BCGs. The mill work under the gas key was rough and that led to a substantial amount of gas leakage around the base of the gas key. Maybe I got a lemon but for the money I would just stick with the phosphate or nitride versions.

Dosent work
I purchased this for a build I was working on. It seemed like the bolt was very tight in the carrier and the finish was rough it has mill marks all over it. I took it out to the range and it wouldn't cycle at all. I swapped it out with another BCG and had no problems with the gun. It's back at PSA for a repair or replacement. They were very good about taking it back and hopefully I'll get a working BCG soon

Will definitely buy another
I bought the $99 PSA bolt carrier group off the website for a budget build. Many posts on various firearms websites complain about shipping time on PSA items but my order was at my door very quickly. I still did not expect too much since a lot of folks knock PSA and my only other AR sports a $250 bolt. But the PSA ended up being a real bargain: the gas key bolts were well staked all the parts had a nice boron nickle finish and the finish work was very smooth. I was so happy with the bolt that I ditched my plans to assemble a rifle and just bought a semi-custom finished upper and a lower from PSA!

Great mid to high tier BCG
A great BCG for its price! Vast improvement over phosphate. While
a few very mild cosmetic machine marks were noted in non-friction surfaces all the business areas were perfect. Good example of function over form I don't need 10/10 points when 5/10 is utter functioning reliability. Will be buying more for future builds!

Very nice BCG in nickel - boron finish
I purchased a PSA nickel boron BCG to accommodate my newly acquired Springfield Armory Saint. It arrived in four business days and was packaged very well. After close inspection I believe the PSA BCG has been manufactured to very high standards. Nice smooth finish and no excessive tooling marks. Between major snow storms(Northeast)and a good bought of pneumonia I haven't been able to actually test it. Spring will be here in just a few days. Hopefully I will be well enough by then to take her out for a spin at the range. Looking forward to some fresh air and some quality shooting time. It's been a long winter up here!
