^^^^ This.

The Smoke Composites handguard is super light but solid and wobble free. Taylor Freelance JP Fattie magwell is the only way to go. Mounting system is way better than Tech well. Can't go wrong with the JP 45 degree mount. Shouldn't be any problem removing the dissipator.

That's correct. I'm using a 124 JHP.

Just put a Smoke on my JP. I really like the feel. I don't see any increased bounce. YMMV. I went with 13". There was no charge for custom length, just charged me for the 14". Ordered Tuesday morning, got it Friday

In my case, I was working up a load and noticed what Black Buzzard mentioned. I've settled at ~135 pf and runs like a champ.

What specific powder and bullet were you using? I tested every SCS buffer available with 115's at 110 PF and they all cycled and locked back. I was able to get a 95 grain bullet down lower than that to cycle. ____________________________ Titegroup/Montana Gold 124 JHP

I've experienced the same thing with mine.

Like egd5 said, the JP will feed pretty much everything well. Load for the magazine/s, that's where any problems may arise.

JP. Just recently went through the same decision. After seeing all the MPX problem threads and iffy Sig support/factory parts availability, I went with the JP. No regrets. After tuning the buffer, its soft and extremely flat. I'm sure you'd love the MPX too, if you get a good one.

My order was confirmed on 26 March, so about 7 weeks and still counting. Mine is also pretty plain (no bling). I'll pm you when I get the shipping notice.

Welcome aboard!

You mentioned it would be at every steel challenge match, what about USPSA PCC? Which barrel do prefer for that?

Or just go through the posts on this forum (PCC) and read the problems members have experienced with each (MPX vs GMR-15). To each his own.
