Custom built LMT Lowers

AR/M4 AR General Discussion
1

Customers are constantly asking for LMT lowers with this part or that part added or removed. So to “help a brotha out” we have decided to do some packages for folks. We can use just about any stock or grip (VLTOR, TD, Magpul, etc) and also add different receiver plates, buffer weights and even different types of buffer springs.

Below you will find some lowers we have already put together to give you a better idea of what you can get. The LMT lowers come with LMT LPK’s (FYI).

I have a question about the H Buffer I see many M4s using a carbine weight buffer my LM&T Defender 2000 came with one. Where is the H buffer needed in the carbine length AR?

5

I am wondering the same. I had no idea that H buffers are actually designated with an H on them.

I was under the impression that my LMT defender 2000 lower had an H buffer but i guess im wrong since its not marked.

Grant, will the packages be available in other colors?

I never could tell the diff in a car buffer and an H buffer in any of my carbines. feel the same shoots the same to me . but all my carbins now have H buffers ,but I’m nerotic.:confused:

Grant,
A friend of mine and I have been waiting on our LMT lower for quite a while now, when are we going to get them?? I can’t wait!!

my experience is second hand with this. while qualifying with the M4, another officer had brought his own M4 down and was just shooting it; having problems also. Range officer swapped out the man’s buffer and put in H buffer and problem solved.

It may have been an ammo issue, but the shorter gas system on the carbines isn’t real friendly toward the weapon’s cycling abilities and changing the buffer is one of the easiest fixes. don’t ask me why the shorter gas tube would cause this, can only relay what i have seen. On the 16" middy i’m building, i’m starting with an H buffer.

Good idea Grant.

10

At a minimum I would use an H buffer with a carbine gas system and really be looking at H2’s and H3’s.

Negative. All LMT lowers and complete AR’s come with car buffers.

This package will be available in colors.

No idea who you are or what you are talking about (sorry).

Grant I found this chart at http://www.biggerhammer.net/ar15/buffers

Are the weights correct as to the Car buffer and the “H” buffer that can be bought today?

14

Grant,

What about one of the kits with just a standard trigger set up?

15

What hammer is that? I see it’s notchless…

16

They look close. Here are the numbers that I generally find to be true:

Standard CAR 2.9 oz.
H buffer is 3.8 oz.
H2 buffer is 4.6 oz.
Rifle buffer is 5.17 oz.
9mm buffer is 5.5 oz.
H3 buffer is 5.6 oz.

I am not sure what a standard kit is. The triggers that are the in the above lowers are a standard LMT USGI trigger.

Grant,

Gotcha. I though they were somehow different (or I read it somewhere) that they were different. Damn, if I was home right now I would scoop one up.

19

I did not mean to take the thread off your intended subject but I just wanted to know what to expect when ordering a custom lower and asking for a special buffer.

Why the CMT 6 position receiver extension and buffer spring? Why not the LMT versions? Did you put the lowers together from scratch or just modify them?
