Anderson Manufacturing Stripped A3 Upper Receiver


great upper, finish was perfect and matched an old lower i had from the 70's perfectly. i will be buying more in the future for other builds. but as usual it went on sale a week or so after i bought it. i could have saved ten bucks but still a good deal.(update) well i bought another one and i must say just as good as the first one and a better sale price too. could not believe how fast the shipping was to washington state. i think i had it in hand in two maybe three days. i love primary arms cant wait for black friday to start!

Anderson upper receiver


I bought this item for a future project. The upper arrived as described and appears to be good quality. The item was shipped the same day i placed the order.

Great value AR Upper


I bought this receiver to complete a lightweight budget upper. No fit or finish problems at all, and a really good price. I'd give it 5 stars if it had white T-marks. Other than that, no complaints.
