Most Helpful Positive Review billet receiver
I have this receiver for an AR target rig setup using a Bruce Finnegan barrel and a Battle Arms enhanced bolt carrier group. I could not be happier with the attention to detail that this receiver has. Absolutely no sharp edges near bear surfaces, looks like a interior coating for the bolt to ride, and with my particular barrel the install did require a little heat from a heatgun for proper seating which is excellent for the purpose of my rifle. Makes things very snug right where it needs to be!!! Outstanding choice for a precision oriented build!!!

Spikes tactical quality parts at Opticsplanet.com affordable prices. Sign me up every time!

by deprazor, Verified Owner from FL, United States Written on November 22, 2025
I've been a fan of Spikes Tactical for years. My first foray into building an AR was well supported by parts from Spikes Tactical. I love their spider logo. The parts are built to mil-spec standards, fit properly EVERY time, flawlessly machined, flawlessly coated, and have never failed me on any build. I have now purchased two of this Spikes Tactical Billet uppers and I will probably purchase more if they stay available and the prices stay as reasonable as Opticsplanet.com have kept them. It is awesome. It mates up to Spikes, Aero Precision and just about any mil-spec lower you throw it on perfectly. The quality is undeniable. Thank you to Opticsplanet.com for THE best price on the net. Period!

The upper they sent me is NOT the same

by Gunguy, Verified Owner from RI, United States Written on April 5, 2022
The upper reciever i ordered was the one SHOWN IN THE PICTURE . They sent me the WRONG one . I got the version with all the ugly dimples on the opposite side of the dust cover . They NEED TO UPDATE THE PICTURE very disappointed. If that was the case i could have gotten the same upper for cheaper on wingtactical.com if i wanted THAT SPECIFIC ONE . But I purposely bought it from here because it was the one without the dimples

I'd recommend this product to others for their builds but not for my intended purpose

by JD89889, Verified Owner from SC, United States Written on September 17, 2021
I purchased this upper because of another review and having read elsewhere that the inside diameter for the barrel is undersized compared to mil spec requiring the use of a heat gun to fit the barrel. (similar to what JP calls thermofitting). Ideally I wanted a JP15 upper, but only the JP CTR02 upper ever seems available, and the CTR02 doesn't include basic features such as the ability to install a dust cover. Having read that this comes with an undersized ID for the barrel extension and required heat to fit the barrel I was expecting an upper similar to the JP15. I was disappointed to get this and find out that the ID is just plain old mil-spec. When I noticed my barrel fit right in with a little slop just like with other regular uppers, I checked it with my calipers, and sure enough, it measures right dead in the middle of the tolerance range for mil spec.
Pros:
  • None
Cons:
  • does not have an undersized ID for barrel as other reviewer stated
Would recommend: Yes

Spikes Billet Upper Receiver

by Long, from TX, United States Written on November 26, 2020
Got this upper to put on my Spikes no-logo lower. It fit perfectly, as you would expect and looks really nice, with the unique cuts. The only thing I really dont care for is the giant SPIKES TACTICAL on the left side of the receiver.
Pros:
  • Looks nice and fits great.
Cons:
  • Giant logo and price
Would recommend: Yes

Pure awesomeness.

by SpudsMaghee, Verified Owner from NM, United States Written on October 28, 2020
I wanted something unique and perfect. I used to not like spikes but this billet upper and lower I also have changed my mind. Legit! It mates well with my spikes lower duh. My ar pistol feels like a toy it's like 5 lbs lighter than my ar10 pistol.
Pros:
  • light
  • unique
Cons:
  • None
Best Used for:
  • bad asses
Would recommend: Yes

Defected item

by Black, from TX, United States Written on August 17, 2020
I brought this upper for a build and was ready to put it together, until I noticed that the upper was missing the barrel pin slot that is suppose to be in the treads of the upper. Therefore I can’t put my barrel on this upper because of missing slot for barrel pin grove. Can you please help me with this problem. I really want this upper for my build.
Pros:
  • Great and fast service
Cons:
  • Defected piece
Would recommend: Yes
