Having 2nd thoughts about one thing.......

[NoFail]

yeah me thinks maybe I didn't do enough reading and thinking about the big picture and I could have went the wrong way with something. For my JDM upper I ordered from JP Ent. Supermatch 16" barrel mid gas system & comes with enhanced bolt, adj. gas block & Low Mass bolt carrier. I also have slash's Car10 HX buffer with modified Armalite spring. I am wondering if it was a good idea to go with the Low Mass Carrier & will it work well with Slash's buffer & spring too. I'm not really going to be using for serious bench. Target practice yes but hunting & tactical is what my build is about. I'm wondering if I should exchange JP low mass for JP full mass carrier. If you have a better idea than me then, please, what do you think?

the question is are you going to run an adjustable gas block. i might be wrong but the low mass carrier needs to be tuned with the gas. if so i think your good, maybe someone else can help more

Yes I have the JP low profile adjustable already & I understand it's purpose and all that. I think what I worry about now is if the Low Mass BC will still be good with Clint's Car10 HX buffer setup. Not sure I thought all that through well enough & I am inexperienced with gas guns so .....  <dontknow>

Reliability is my main concern with this topic, of coarse.

pm clint from heavy buffers, he's a member here or email him through his site

I'm pretty sure the LMOS has a buffer too. Possibly a spring as well.

The whole point of the system is to cut as much gas as possible. No heavy buffers or special springs. Combining the two systems would be counter-productive.

I think they only have a lmos buffer for the AR-15

Yes this is what I am thinking now, that car-10 XH & LMOS BC is counter productive. Obviously the LMOS would have less inertia and if you throw a heavy buffer in there then LMOS has to have that much more force from gas pressure to help it blow back. I'm thinking you are correct and having to open adj. gas block more to overcome heavy buffer is counter intuitive. Oh darn!! So if this is all true what should I give up, LMOS or CAR-10? Is it necessary to give one of them up?

Run it first, and see how it does.

The JP setup is just that - a complete setup.  The gasport diameter will be something specific from them, for that bolt carrier's weight.  See if it cycles with the heavy buffer, first.  One thing that heavy buffer is going to do is increase the locktime of the bolt in the extension, before it begins to unlock.  That aids accuracy. 

Just see if it runs.  You might have to run a little more gas pressure, you might not.  If you can increase the gas enough through that gas block, it might be a real nice shooter.  If you can't get enough gas through it to cycle it with the heavy buffer (even wide open on the gas block), then just sell the buffer here and move to a lighter one.

OMG 98!!!! You are right. Yeah, Thank You Brother, & thanks guys <thumbsup>

Yeah, I'm still trying to figure out what your inbound package is too  <dontknow>  <munch>

Thanks, Man!!
