Milspec 5.56 receiver extension

LMT Defense has a great option for those building their own MSR. Our milspec receiver extensions, or buffer tubes exceed the quality standards of others in the industry. We time our tubes to have a “no guess” fit with LMT lower receivers and follow up the black anodize finish with dry film lubricant to enhance performance. Finish up your build with our QD endplate and castle nut as well.
