In the firearms game, small parts get a lot of attention, just think about the time you spend choosing a trigger. While you’re busy choosing the best small parts, don’t forget to give a little love to the large parts that tie your build together. A lot of armorers are still using whatever buffer tube is available, but if you really want to build an AR-10 that is everything you want in a field weapon, you should take a little more care than just grabbing whatever multi-position tube is cheap. When you choose a Spikes Tactical AR10 Buffer Tube you’ll get exceptional quality at a value.

  • buffer tube 7 ⅞ inch

    This tube worked great. Some say you can use a regular AR tube and small buffer but when you use this tube you have no problems and can use a longer spring to take up the rear hit.
    Great product and will fit most all stocks that re out there and the stocks don't ratttel.

  • Spikes Tactical AR10 Carbine Buffer Tube

    This tube provided the extra 3/4" in length I needed to be able to use a 3.25" 308 carbine buffer. The threads were tight going in to a DPMS receiver, needed to lube it up with some WD-40 but it screwed in with little effort. Detent pin lock is a nice feature on this mil spec tube, which is of excellent quality and value. Have two different brands (Magpul & Adaptive Tactical) of mil spec stocks that fit nice and snug on this tube. Highly recommend.

    I replaced my original AR10 buffer tube with the Spikes buffer tube in my AR10 build and I am very pleased with it. The Spikes tactical AR10 Carbine buffer tube is 3/4" longer and the spring/buffer pocket is also 3/4" deeper. This extra depth allows you to use AR15 carbine length buffers and springs without having to worry about spring coil bind or the buffer bottoming out too soon (AR10 has a longer bolt stroke because the cartridge is longer). Note: I have an adjustable gas block so I can control the bolt and buffer speed and can use a lighter spring. The "short" AR10 buffers are too short to be used with this buffer tube. It will probably spring coil bind first instead of the buffer bottoming on the end of the tube.
    Product is well made and nicely finished.
