Most Helpful Positive Review Very happy so far!
Ok, so the obviously preferred 7075 T6 Aluminum, position indicator markings, and the whole thing is beautifully coated with a dry-film lube (I believe the inside of the tube as well). I don't see why this receiver extension won't hold up for a long time.

Received obviously returned item, weird color

by David, Verified Owner from FL, United States Written on January 21, 2026
Needed a decent 7075 aluminum buffer tube at a decent price for an AR build. This one seemed to fit the bill. It arrived quickly, but I noticed the shipping label said it shipped from "returns" at optics planet. Sure enough, the tube had multiple nicks and blemishes in several spots, exposing bare metal. It is also a very weird shade of black that will stand out in a bad way on any build, it almost looks blued. Should have gone with a different brand. Bad on OP for selling a blem product as new.

Super Nice Buffer Tube

by RangeKing3, Verified Owner from TN, United States Written on May 21, 2025
The Spikes Tactical Mil-Spec Buffer Tube is an excellent upgrade for anyone serious about reliability and performance. While it’s a bit pricier than bargain options, the superior build quality and long-term durability make it worth every penny. Once installed, the performance was flawless. The tube provides a snug fit for the stock, with no wobble or rattle, which gives the rifle a more solid and professional feel. The internal dimensions are perfectly mil-spec, so all the other components (buffer, spring, and end plate) fit perfectly with no issues.
After hundreds of rounds downrange, it shows no signs of wear, which speaks volumes about its durability. Whether you're building a new rifle or upgrading an existing one, this buffer tube is a solid investment.
Rating: 5/5
A rock-solid buffer tube that delivers on performance, durability, and ease of installation. Highly recommend for any AR-15 build.

Best buffer tube on the market

by cciummo, from AZ, United States Written on August 13, 2023
Spikes Tactical buffer tubes are hands down the absolute best you can find, better than Larue.. better than Bravo Company.. DPMS.. CMMG.. all of them. Dry lube brings flawless operation to most buffer springs and without the twang sound of most others. Do yourself a favor and get one of these along with their buffers, which are also top of the line. You get what you pay for. After 30 or so builds, these are the only ones I'll use. Thankfully i learned early.

Milspec plus

by Marc, Verified Owner from CA, United States Written on July 11, 2021
Good quality buffer tube. Kind of disappointed it doesn't have a spider logo anywhere. It is marked (ST) for Spikes Tactical. Also has each position marked with white numbers 1-6. The package arrived with normal expectancy ordered during free shipping.
