MemphisMechanic Posted June 15, 2017 Share Posted June 15, 2017 Question for the PCCers as I begin to contemplate a new build: I see many of you are running a JP SCS recoil system, and perhaps their bolt. And lots of mention that their barrels are one of the few that'll let you load long for 9mm use. Why aren't complete JP uppers more common? Is it strictly a price thing, or is there another reason?

mahamoti Posted June 15, 2017 Share Posted June 15, 2017 I looked at buying a complete JP upper. I didn't particularly want their handguard or comp. Their upper receiver, you can only pick from milspec or their ($600) side charger. Basically I picked up the JP stuff I wanted (barrel/bolt/SCS), and assembled them with other parts I preferred.

MHitchcock Posted June 15, 2017 Share Posted June 15, 2017 (edited) Price, handguard preference, and wait time seal the deal for most people. I have a GMR-15 and it's a monster. But I also shoot a JP SCR-11 in 3 gun so I'm a fan of the handguard. A stock GMR 15 was 4th at nationals, and the gun wasn't the difference between 4th and 1st. In fact JPs were the most common factory gun at nationals by more than double. You can't go wrong with a JP, but if you are planning on changing a bunch of stuff out its a waste.

What is the go-to lightweight upper of choice for PCC? And aside from their rather popular comp, what did you choose? Taccom? Link to comment
MHitchcock Posted June 15, 2017 Share Posted June 15, 2017 (edited) There is no go-to as personal preference plays a huge role. Most other stuff is home built. However, if you want ultra light weight it's going to be a taccom barrel 15(oz) and Carbon handguard (<6oz with barrel nut) and a slick side upper of choice with a charging handle of choice. I built one to play around with and it's nuts how light it is. other than that, KVP makes the lightest regular barrel offering (19 oz w/o muzzle device) but the chambers can be short and require reaming to run longer ammo. There is a barrel maker thread in this forum, search PCC barrel maker. The other lightweight handguard are a preference thing and the lightest ones are around 9 oz with barrel nut for 12 inch 11ish oz for 15 inch. ***edit- on a side note, taccom preps their barrels like JP so you can load long*** Edited June 15, 2017 by MHitchcock Link to comment

Since I don't expect any comp to really do a lot of work, I wanted shorter profile. Went with the Nerd Nano. Link to comment

MHitchcock Posted June 15, 2017 Share Posted June 15, 2017 There is more dot movement compared to the JP, but it's basically straight up and returns quickly. I haven't had it long enough to play with the buffer weight\springs yet. So I may be able to tune some/all of it out. I think it's just a product of weight differences. I think the comp does something, but it's a small percentage compared to .223. It's 95%+ recoil spring/buffer driven in a blowback. Link to comment

A stock GMR-13 took 7th at the nationals I know that. [emoji12] Link to comment

Roy T Posted June 16, 2017 Share Posted June 16, 2017 I think you know its the singer not the song when it comes to what gun finished where. I have a GMR 15 on order because I have used JP products for some time and appreciate not having to tinker (at least I have not). The earlier answer that referred to price point, wait time and some handguard issues (I got the ape hands so its not a problem for me). If you want flexibility then you may be best served by the DIY method. My buddies like to tinker but they also drink a lot Link to comment
MHitchcock Posted June 16, 2017 Share Posted June 16, 2017 You'll love your GMR. Huge fan of my JPs. I also like to tinker Link to comment
T Bacus Posted June 23, 2017 Share Posted June 23, 2017 My upper of choice on the three PCC's I've built has been the Aero Slick Side. No need for the FA so why have it? Makes for a very clean looking rifle. As for comps, I've used the JP on two and an Armalite comp on the third. I opened the comp up to 9MM, sent it and the barrel to ADCO and had them cut and re-thread it so the barrel would be just over 16" pin and welded. It came out pretty nice. Link to comment
