“Good as any I’ve used”.

Good as any I’ve used,
I purchased this stripped upper for a 5.56 build project because it was on sale, when I received it I was pleasantly surprised on how it looked and felt, I put it together with no problems, the fit to my lower was very tight no need for the accu-wedge I purchased. It looks like it is a lighter weight receiver cut down a bit in some areas but it is a strong unit, and the anodized finish is flawless and receiver very cleaned up with no blemishes on the forging and machining. I will definitely buy more because of the craftsmanship put into it, don’t let the name keep you from buying it, like I said “ Good as any I’ve used”
When I bought it I never heard the name Willow defense, but I’m glad I bought it, in fact I take the name Willow, as how light weight it is like a willow leaf, 5 star product for anyone wanting a great lightweight upper receiver, it is exactly that, you won’t be dis-satisfied, good stuff.
Thanks, M.G.

Willow upper

A very affordable mil spec upper that works just as good as the other ones but costs way less. T marks are nice too!

Awesome upper to build

This is an awesome upper to use on your build

It's an upper

Does what its supposed to do. The finish definitely has some texture on it, which is interesting.

I got a Cerro Forge one (keyhole marking).

Dust Cover Issues

by -

There appears to be an issue in the Willow Defense Forged AR-15 Upper Receiver. This review does not reflect on Primary Arms, but Willow Defense alone. I received the upper receiver and began the assembly process. I had no issues at all with the forward assist, but I found that the gab between the ejection port and the dust cover was a little out of spec, causing the a standard ejection spring to struggle keeping tension as it would slip underneath the cover. Furthermore, the dust cover would not shut. Marks on the receiver indicated that it was not machined correctly and it was to tight to close. I attempted using a different cover, but the problem was the same. The receiver will have to be filed in order to work correctly.

We were happy to speak to you on this and get you taken care of.

Great product

What a deal this was on sale. Fit and finish are great and fits well with my palmetto lower.

A great mil-spec stripped lower

by -

Right out of box, you can’t beat it for the money. It arrived three days after it was purchased. It was as advertised without any problems or blemishes. Everything fit nice and tight.

Great upper

Bought 3 and has nice T marks it matched my BCM MCMR perfectly.

Very good stripped upper.

The Willow upper works and functions great. I cannot tell the difference between the more expensive uppers I have used. Good for the money.

Works

Works great. Everything gauges out good. Not a big deal but it doesn't come with "t" forge markings. At least mine came with Anchor Harvey forge marking (splintered A). Makes no difference. Great price, may even replace BCM blems for me in the future.
