Anderson Manufacturing AR-15 Upper Receiver Assembly

I use 3 different anderson lowers and this upper fit the tightest of my 3 other uppers.fit and finish is great

I received my upper within three days, condition was good and this product was as described on web site

I really try to order everything I can from your site.

I ordered this upper to match an anderson manufacturing lower I had purchased at a local gun store for a pistol build. The upper was as I expected. No scratches and perfect fit. The barrel I ordered fit perfectly. M4 feedramps lined up great. I love ordering from primary arms. Great customer service and your product is on its way in a very timely manner. I will always shop with this company first.

I ordered an upper receiver and a gas block on Tuesday and received it on Friday. Both came in in great condition and have already been installed. I will use them again!

I like it....!!! :-)

I just ordered this item on Tuesday and received it already Thursday. I had previously bought an Anderson stripped lower for a project and this item fits perfectly with the lower. The color is perfectly matched and functions well. Although the rail slots are not marked or numbered, it was not an issue for me as I tend to place my optics in specific slots anyway. I would buy this again for a future project build.

I have built 4 uppers now Anderson receivers and all have been perfect. I square all my uppers with a lapping tool and these are already almost perfect out of the box. I see no need to spend more on a forged upper when these perform as well as any.

I have been looking for uppers for my AR 300 blackout build, Anderson had great reviews. I will buy another one for my next 308 build.

I had hopes for this upper since it was advertised as "MILSPEC". Unfortunately it is not MILSPEC. The upper does not have T-markings, the M4 feed ramps are rather weak and it did not have the dry film lubricant applied inside. Overall it will be functional, but it's not MILSPEC.
