Thanks to Grant, I am the proud new owner of an LMT Defender lower with SOPMOD. This is my first LMT, and I’m very pleased with it. However, upon first inspection I immediately noticed something different about the receiver extension/buffer tube. It’s sort of a silver-gray in color and has a smooth finish. It feels like it might be Teflon or dry-film coated. Every other receiver extension I’ve seen had a finish similar to that of your typical upper or lower.
Is this an LMT thing? Does it have something to do with the SOPMOD stock? Who else (if anyone) makes receiver extensions like this? I have no complaints. I’m just curious. I know someone will ask me, “What’s up with that buffer tube?” and I’d like to have an answer for them.
Well, in my continuing quest to dissect my new lower, I have come up with another question. What kind of buffer comes standard in an LMT lower? I only have experience with CAR and rifle buffers. The LMT one “feels” heavier than my CAR buffer, but I don’t have a scale sensitive enough to weigh them accurately. It has no markings on it whatsoever. Again, I’m just curious. I’d like to know what I’m starting out with in case I run into any issues in the future.
