Normal 3 port steel compensators on both. I shoot Federal 130 Syntech mostly. I do also run the Syntech 115, 124 and 150 grain loads but I tuned everything up to be optimal for the 130's.
That's the Taylor Freelance magwell. It's very nice and well made.
The stock is the MFT minimalist.OK, good to know that your set up is flawless with both lighter and stronger ammo.
I see...and does that magwell make any real diffence in mag exchange or is is just an aesthetical touch;-)?

Yep, I know some folks prefer a different setup than my 10.5 twins
I'm actually doing a bunch of testing in the off season with the new vertical comp and a few other pieces to see if I can keep the fast feel of my current setup with a little less vertical movement. To me, the rifles hardly move but I know several folks prefer the 2-5 tungsten SCS systems in my 10.5's instead of the 5 stainless.
Welcome to the club @Dkrad1935!
What a nice pic!
You do have “normal” comp on both if I’m not mistaken, right?
What loads do you shoot?
Would you recommend that magwell you do have?
And how about the stock...is that the JP minimalist one?

Nice rig. I was able to shoot a similar rifle at the JPP both at PCC nats. It was nice but I did not note the dot bounce with the 5 rounds I fired.
Super curious to how the dots moves with the shorter barrel. Let us know what load you use and how much dot movement you see.
Also, for quicker safety movement you might want to consider the Radian Talon 45 degree ambi safety. I put them on all of my gamer rifles.

Yeah, would also like to know how the dot moves with a shorter barrel.
And what is the issue with safety please?

Build list. Now if I can just figure out how to get base pad off the 33 round magazines I’ll have the really big stick!!
Sent from my iPhone using TapatalkNice one:-)
When it comes to buffer...what portion off steel and tungsten do you have please? I can’t find it on the build list...

I don’t think the comp matters that much. But. They recommended it. Recoil is an absolute non issue. So I can’t imagine making it significantly better.
Sent from my iPhone using TapatalkYour comp is titanium one if I’m not mistakem...so good to know that.
And what loads are you shooting please?

The stock is fine. I’m new to this kind of set up. So am still trying to figure out proper way to mount it. Out a holosun on there and it’s pretty easy to see quickly. I like the weight and balance. I’ll have to check the build to see what the comp is. The trigger is the flat competition trigger. The thing is awesome.
I’ll try to post a build pic in a bit.
Sent from my iPhone using TapatalkIs that a velcro on the stock? And if so, why?
It is Holosun 510C if I’m not mistakem...isn’t it a bit high in contrast with the stock?

I just received my jp. It’s an 8 inch barrel. First trip to the range and it was flawless through 350 rounds and all the glock mags I had.
The thing is like butter. Love it!!
Sent from my iPhone using TapatalkThanks fot sharing, man!
My take is 10” barrel with M-Lok handguard and a basic upper, but color-wise the same combo probably...black with blue.
What comp did you get? And what trigger? And how is that stock?

There is an interesting discussion about PCC with some JP shooters:
Lessons Learned: PCC Nationals
About 18 Min. they are talking about barrel length. I fully agree with them.
Thanks for sharing. Seems to me my preference is to be a good one;-)
-
I hope I’ll have time to write JP tomorrow...gonna mention that as well.
Suppressors aren’t legal in my country, so this won’t work for me...unfortunately.
Thanks for your opinion on barrel length. This vertical comp is an interesting stuff for sure...so your initial experience says it helps to control red dot/muzzle bouncing?

Thank you, sir:-)
Works fine, the only problem is they don’t offer an option to choose 9.25” M-Lok handguard with 10,5” barrel at all, so it seems to me I need to contact JP anyway:-(

I have a ready rifle. I primarily shoot UPSA and steel challenge with it. The only thing I've changed is the mag release and a short stroke kit. I am thinking about changing to the new vertical comp.
Vertical comp should do what? Less gun/red dot bouncing?

You obviously aren't a US resident so is there a 16" minimum barrel requirement in your country? You could save significant weight from the barrel and handguard if they could be legally shorter. JP offers a 10-1/2" barrel in 9 mm and handguards down to 7-1/2" so you may consider these if you can.
Nope, I´m not a US resident and there is no minimum barrel requirement in my country. So, thanks for this comment
The point is there is no option of 10,5” barrel in JP rifle builder. It is possible if I try to build upper assembly though. And when I opt for 10,5” barrel and 9,25” M-Lok handguard (7,5” is too short), it means 0.6 lbs less and brings me below 6 lbs in total which would be great! I´d just have to contact JP people and ask how to proceed if I want to build the whole rifle with such barrel length.
Just not sure about the ballistic and especially gun bouncing when shooting with 10,5” versus 14,5”/16” barrel length. Any experiences please?

I bought a GMR-15 Ready Rifle due mainly to impatience. The only JP part I've changed is the mag release. It came with the standard, but I switched it out to the extended. It gives you more leverage, and it feels easier/lighter. Mine has the ultra lite barrel. I wish they offered a lighter hand guard. With a Tech Well mag well, C-More rail mount, a laser and 5 tungsten weights, it's close to 7 lbs. I'd love to lose 8-10 ounces of hand guard weight. I also have the factory comp trigger. It breaks at 3 1/2 pounds with a very positive reset. I wish it was closer to 2 1/2.
Well, 7 lbs is really heavy for me. I´d prefer 6 lbs max. Is that Tech Well mag well really a must? Speaking of trigger…does the lower accept any AR trigger?

I have one JP and have ordered a second. I have the one you pictured except with a stainless bolt and barrel. IMHO they both look better and as noted above also clean easier. Mine also has the Radian Raport LT charging handle which is ambidextrous. JP's do not come with a ambidextrous mag release, however in April JP announced a left sided add on Ambi mag release. You should be able to find it with a search. Not sure if it is for standard AR's only?
Agree, stainless bolt and barrel. Will go for the same charging handle. And thanks for that ambi mag release – will double check and try to get it as well.

I think some of those options were not available when I ordered mine just over a year ago. And some things I just don't remember, but....
The Titanium comp wasn't available then i don't think. But I don't think it would be worth spending very much more for, IMO.
I don't think the release is ambi. but not sure as I'm right handed and shoot that way.
I forgot to include, Mine is the scs short stroke with 5 steel weights. I shoot a 130 to 135 PF load so the lighter weights seem better to me. There's a lot of different opinions about that though, but from all I've read the heavier the load you shoot the more weight you need in the buffer. But tuning a pcc for no dot bounce is somewhat of a voodoo science all to itself.
I wanted the top rail because I mount my laser there for those hard left lean shots in competitions. That's all I have mounted, no adaptors.
The smoke comes with all you need. I went to a gunsmith to mount mine simply because he has the vice to hold the gun so it can be worked on easily. We did have to put a couple of tiny shims just to get the rail to line up just right, but if you don't get a rail I don't know if that would be necessary.
I just went with the standard competition trigger (3-3.5) Andre recommended, No trigger shoe, just the standard curved one that was no extra cost. I don't know what an Armageddon one is.
Yes, seems to me they are changing the options constantly.
Hmmm, will check the ambi stuff for sure.
Well, I am going to be shooting mostly factory 115 and 124, so I guess I need to talk to my dealer to decide the steel/tungsten ratio is scs short stroke. Will also discuss the trigger with him.
OK, great, so if I go for 14,5 barrel, I can order Smoke Composites handguard with no worries.
-
Yes, a lot of options. The problem is I almost have no chance to try this rifle before buying (except for getting my hands on one in the store) as JPs are not that popular in my country. The main reason is price – they are simply too expensive for most of the shooters due all the fees to be paid for US goods import. So I basically don´t know what to opt for when building one. And that's why I am happy for any personal preferences and experiences.
14.5 barrel for sure. I don´t believe shorter or longer makes much sense to be honest. Stainless steel barrel and compensator is what I'm looking for too. And how about titanium compensator, is it worth extra money, what do you think? It's definitely lighter than stainless steel, but any other (dis)advantages?
Stainless bolt then, thanks for a recommendation. I was also considering the extended mag release, so thanks for confirmation. Is it ambidextrous by the way? I´m right handed, but my left eye is dominant, so I shoot rifles and shotguns from my left shoulder, using my left hand to pull the trigger etc.
Well, ADD weight to the gun…why not…but definitely not to the front of the gun from my point of view. So, I´m with you in this. And, plus 9mm Luger is sort of kicky no matter how heavy the front of the gun is. I believe that if for instance a short stroke system is chosen etc. the GMR-15 recoil can be reduced significantly. Not as much as in case of .223 Rem, but enough to make shooting fun. Any recommendation on what to choose in JP rifle builder to achieve a minimal recoil please?
Smoke Composites handguard – yes, checking their webpage I can see it´s either version without top rail (outside diameter 1,69”) or version with top rail (outside diameter not mentioned on the webpage). I´d go for the version without top rail as I don´t think I need it for anything. Do you also use any Magpul M-Lok adapters on your handguard (If they are compatible at all)?
OK, so I´ll ask JP for a barrel nut tool when ordering, thanks for this. And does Smoke Composites handguard come with all the stuff (bolts, screws or what is necessary) necessary for its installation to a rifle upper? And are any non-standard tools needed for this installation, please?
Speaking of trigger, I did this preliminary configuration in rifle builder:
Trigger Style: JPFC-M Modular Trigger
Trigger Module w/ Interchangeable Shoe
Approximate Weight: 0.2 lbs $112
Trigger Shoe: Armageddon Gear Revolution Trigger $0
Trigger Weight: Competition/Recreation Trigger JP Modular Trigger with 3 - 3.5 lb. pull $0
Is it the same as yours? And what kind of trigger shore do you have? Curved, flat or that Armageddon one?

Hi all,
I’d like to ask the JP GMR-15 owners a couple of questions. Preferably the ones who have upgraded their weapons with carbon fiber handguard.
I’m in the process of choosing my first PCC a decided to go for JP as I want to shoot and not to worry about anything. Sig MPX was an option as well but since it is basically unavailable in my country (and the same goes for any spare parts should I need some), JP is the only option now.
I shoot for fun, but pondering to try some competitions in the future.The first question is whether to go for the one from ready rifles or to use JP rifle builder? My JP dealer does have this one in stock:
https://www.jprifles.com/buy.php?item=RR-GMR15APC
If go for a different one, I'll have to wait a couple of months (I live overseas). But I have no problem to do so as I don't want to hurry anything.
Generally, I do like lightweight and low recoil rifles with a light (sport) triggers with a short reset, so I prefer my GMR to be the same. Based on your experiences - is it possible to achieve better recoil or get a lighter trigger by choosing a different components in JP rifle builder?
Speaking of weight:
Is it worth to go for a titanium compensator?
I'll definitely go for a non-standard JP handguard as the standard one is heavy for me and its diameter is too big for my small palm & fingers. Since I don't believe thermal dissipator is necessary, I see two options here:
1) JP M-Lok - diameter looks much better, but its weight is only slightly lower - it's still sort of new, not even on many pictures...any experiences with that please?
2) some carbon fiber - Smoke Composites (12") looks the best to me (did some market check and people on this forum recommend it as well) - its diameter is fine as well and weight is hard to believe (5.37 oz vs 13 oz for the standard JP one), but since my JP dealer is focused on Lancer carbon products, he is somehow reluctant to provide any support related to Smoke Composites handguard, so I'm wondering how complicated is to change the handguard at home (I'm not that skilled in such stuff to be honest), if any non-standard tools are needed (both for removing JP handguard and installing the Smoke ones) and mostly whether is comes with all the stuff necessary for mounting to the weapon?
Is the Smoke Composites handguard sturdy enough, please? Any wobbling when shooting? And how about heat conduction when shooting more rounds in a short time?Any other reasons to go to a rifle builder (except for stuff like different trigger, safety and mag release color) in comparison to a ready rifle, please?

Thanks for you range report.
Did tou notice any difference in gun bouncing when shooting different ammo? I mean you do have short stroke with 5 steel, which I am thinking to get to shoot 115 and 124 S&B ammo, but also do have a great source of remanufactured ammo (147) for a very good price...which I am using in my CZ-75 TS Orange pistol
