I'm not one hundred percent positive, but I think you have to have a shorter tube, pistol tube or what the correct terminology is to stay legal.
Please correct me if I'm wrong. Just remembering gun shop talk

Thanks for the info. I looked at the RRA pistol extension on their website just now and I like the looks of it... plus its only like $25. I do not want to have a proprietary spring and buffer for this pistol build, and like to keep parts standard. So I will go with the CAR length tube.
I had not originally planned on building a pistol, but a few months ago when I bought a couple of lowers, the vendor mistakenly sent me one marked pistol. Since it is a virgin lower, and was transfered to me as a receiver... I am GTG. My thoughts are that I will build this pistol using an LMT 10.5" upper that I can use on a SBR lower later if I choose to go down that road. And the pistol lower will be easy to sell later, possibly at a profit. If I end up liking the pistol then of course I will keep it, as one can never have too many black rifles or black pistols :) I do think it has some practical applications with the 10.5 inch upper.
Next question... would you guys recommend a standard CAR buffer for the LMT 10.5 upper or the H Buffer? It seems like I have read on here that the LMT has a smallish gas port so the H buffer is not necessary... any drawbacks to the H buffer if it is not really needed? The H buffer is about 2x as much $$, so would rather not spend the extra dough if not necessary, but I want the gun (like all of my guns) to run 100%.
Thanks!
Where the heck are you shopping that charges 2x for an H buffer so I can avoid them like the plague?
YIKES! I guess that's the going rate? I could have sworn I only paid like 7 bucks more for my H buffer and 12 bucks for my CAR.
It looks like Rainier is charging a similar premium on the H, but 9.50 for the CAR, 18.95 for the H. If you can't swing the extra 9 bucks to help the gun run like a top, we've certainly hit hard times :(
If I could not afford an extra $9 or $12, I wouldnt have bought an LMT upper. :rolleyes:...But I dont like to spend more than I have to unless there is a good reason to.
Can anyone comment on the best buffer to run with the LMT 10.5" upper?
Thanks

This should help a little.
I ran a H buffer with my pistol and it worked pretty well. Others have reported H2 or H.
Thanks for the link. I spent some time reading the thread you linked, and all others I could find on here regarding the various buffers. What I have learned is the following:
LMTs tend to have smaller gas ports than most, LMT ships complete guns with CAR buffers.
LMTs will probably run 100% (non-suppressed) with the CAR buffer
The H Buffer can't hurt and will probably aid in reliability with all ammo types.
And in an unrelated development the LMT 10.5 that I pulled the trigger on is not available. So I just now ordered BCM 11.5 upper instead. Cant wait to get it together! :D The sale that Bravo Co is running right now on their uppers and BCGs rocks!
It's more like LMT has the correct gas port size. So will a BCM, that's what I ran when I had a pistol.

My AR Pistol will likely end up heavier than my Rifle.:D
