Do you need Gas Pistons...

Thank you Stephen and twl. I was actually looking into the MGI for my LW upper until I read that LW didn’t recommend it for their upper.

I’ve thought about the Enidine, but I’m not sure if I should further complicate the rifle…although since mine’s just for fun, I don’t think reliability is too big a factor.

Thanks to both of you for explaning bolt bounce. Once I get my SBR paperwork done and can actually fire my uppers, I’ll have to evaluate the issue and change buffers accordingly. I appreciate all your help and explanation.

If you want to experiment, I’d start with a $25 9mm buffer. If that works try an Enidine or MGI. Not trying to talk you out of either of the others, but if the
9mm doesn’t work you’re not out around $100. The Enidine works in my POF for what that’s worth.

Thanks for the suggestion TS. I’ll probably go with an H buffer first…supposedly that’s what LW recommends (still waiting on confirmation).

If that doesn’t work, I’ll go from there.

Thanks again,
Sean

Do any of you gentlemen have expierience with the TUBB - CWS bolt Carrier Weight System ?
If I recall that system is designed to combat / eliminate bolt bounce , slow the rate of fire and smooth out what little recoil there is . Is it not ?

65

I just pulled my buffer from my LMT lower…it has no “H” marked on it anywhere. Does this mean it’s just a standard buffer?

Thanks,
Sean

Yes, it should be a standard. It would have a “H” on the front if it was an H buffer.

I would not use a 9mm buffer. The 9mm buffer is just a static weight to hold the bolt closed a bit longer in a blowback 9mm. It does little to nothing to help bolt bounce.

Thanks Todd. Guess I’ll need to pick up an H from somewhere. Any recommendations on where to get an LMT H buffer and what should I expect to pay? EDIT Stickman has 'em for $16.

Thanks,
Sean

Oh, on a side note, my CLEO signed off my SBR paperwork today (after 3.5 weeks)…going to pick it up and mail everything off to BATFE tomorrow. :slight_smile:

I’d get the H2.
If you are going to get any DI SBR uppers the H2 will already be in your SBR lower.
