I Iove the JP5 and it’s round MK3 handguard but, coming from a Brekke, it was too front end heavy for me.

 

I switched out the Handguard (13.5”) and buffer tube for Smoke Composites and switched the stock to an MFT. This shaved off 18.5oz. 
 

Others will hate it, but I like it. 

 

Whats the total weight after changing out those items?

Why?  I did exactly the same thing on My Leadstar Prime.  Now it balances perfectly.  What is sacred about running it the way the manufacturer sells it?

Thx! It’s the JP Flat trigger with lighter springs. The Hg is the Smoke Composites PCC HG but at 13.5”. A custom length which I asked them to build. They will make a custom length if you email them.  
 

I also added the 70° block and it recoils even softer now. It’s just dumb, after the PCC and all upgrades, including optic costs, I spent way too much.

I was told by JP you cannot change the shoe that comes with the trigger. You have to get the trigger that allows the shoe changing. Is that true? If so, did you completely swap the trigger?

I bought their drop in flat trigger. Removed their hammer and shoe as I hate curved triggers. I wish I could use the Hiperfire ECL but it won’t work due to the JP5 ejector. 
 

I bought a Hiperfire PDI-GS and it’s good but not as good as the ECL as the reset is longer on the PDI. Also longer reset than the JP trigger but lighter in weight.

Awww okay. Makes sense. I am waiting for the custom ordering options. I think they are starting them soon.

 

Also, I see a lot of guys running the Titanium/Steel Challenge Comp vs the Vertical Comp for USPSA?

 

Any thoughts?

to my knowledge the only differences are the comp and Handguard, which results in a slightly lighter rifle.

It looks like the SC (steel challenge) version has the original Titanium Comp that ports to the sides of the barrel, and is built with JPs lighter M-Lok handguard and lighter buttstock to save weight.  I assume they went with this comp because in SC can use lower PF ammo that does not expel much excess gas to make use of the vertical comp.

 

The Competition version has a competition comp which is a vertical comp, which might be able to use the gas more efficiently to help with muzzle rise due to the minimum PF of 125.  It comes with the MK III hand guard and a heavier buttstock.  It a bit heavier than the SC version.

 

With all of that said, it looks like many are opting for the SC version for USPSA.  I did and have seen others do the same.  For me it was the weight, and honestly I hate the MK III handguard.

For me, I opted for the first model I could get lol. I actually like the MK3 HG, but it was too heavy for me. This is why I switched out the HG to a Smoke Composites. I also switched out the buffer tube just to match the Smoke HG. I hated the Hogue stock/grip so I changed those as well. Right now my JP5 is lighter than the SC Model.

Absolutely right on the money except for the spelling of the word "skills"

I believe that the best shooters will always win. I also think most of them will switch to this gun.

The note with the FP only said more reliable ignition.

what was the difference in the firing pins ?

 

[Curt Caserta]

I have a JP5 SC and was reading some posts on being finicky with ammo and needing to undersize.  I have not found that to be the case at all.  My JP5 is chewing up RN and FP's and I have not had a single malfunction in approximately 1,000 rounds.   For lighter loads I did switch to a 70 degree locker and it shoots 130PF loads like a 22!!!

I could not tell much difference at all.

I will be curious once they start custom orders and what people will pick.

How did you maintain correct barrel clocking on the JP-5? There is no index on the barrel.  I removed the JP hand guard. Which had a jamb nut to set barrel timing . I torqued barrel nut to 60 lbs . Barrel rotated out of clocking . Are shims available?

The new revised one is physically shorter on the hammer end.

I have tried loads from 90gr HPs, 100gr RN, 105gr FP, 115gr RN, 135gr RN and zero issues myself.,

I think it was to you since you changed your hand guard.

I didn’t remove the barrel so it didn’t have to be timed for head-spacing. Simply remove the Handguard and then the barrel nut then re-install new. Super easy. 

[TroyNolan]

Sir . I did not remove the barrel . As you stated I removed JP hand guard . Installed Smoke hand guard . Returned after firing with barrel clocking past 12 o’clock position . After removing barrel, cleaning threads I realized it was possible to tighten barrel past the 12 o’clock position . I am looking for collar shims .001 .990 OD .807 ID . Any help would be appreciated .

If the barrel came loose, your best option is to send it back to JP so they can properly attach it again. Don't refer to forums for this kind of information.

I trust this forum more than most companies when it comes to any info.
