View thread Contact supportProbably nothing, but it could be a lot of fun! Unfortunately this “well regulated “ cesspool makes getting one impossible.Cheaper than my Vudoo, a little more than my KIDD...the question is what would this do that those do not?![]()
That is what I would like to see...a head-to-head between this and a KIDD!I'd be very curious as to how this compares to a Kidd supergrade.
I think "Pursuit of Accuracy" did a similar video or two with a Kidd Supergrade. He always uses good ammo and gives it a fair shot.I'd be very curious as to how this compares to a Kidd supergrade.
@usafa77 did you and your buddy get a chance to compare the Kidd Supergrade to the JP as of yet? I was on the JP rifle builder yesterday and am torn between it and the Supergrade. I don’t know if the price differential is worth the performance gains of going with the JP. Would love to hear your feedback if you’ve had a chance to put any additional rounds down range. Thanks!I'll give you that Kidd supergrade comparison after I shoot it against my buddy's in 2 weeks.
I have a "normal" JP22 upper, bought their horribly expensive bolt catch, built a dedicated lower for it, have the Kriss 15rd mags... they only lockback occasionally. Not sure the bolt catch is compatible with Aero M4E1 lower. Got some Wolff tube mag springs, cut to Kriss length, increased the follower spring pressure in the Kriss mags and still they only occasionally lock back. Manually locking the bolt open, the catch barely engages the bolt. However, the old Black Dog & the Kriss mags all run 100%. I'm used to not having the JP22 lock open, but it was a very expensive LRBHO experiment that failed. Anyway, the Kriss mags work as well as Black Dog, no wiggle in the lower like 15-22 mags.Holy crap that is cool. Love the side charging option. I’m curious to see if these will cut at all into the Kidd sales.
Hard to think any semiauto will outshoot a Kidd supergrade.
I like the mags on my AR22 upper better than my 10/22’s for not scraping the bullets. Need to try some Kriss AR22 magazines like JP recommended.

Thanks! I'll try modifying the bolt catch spring... at $65 shipped from JP, all I rec'd was the catch itselfI have the same expensive JP bolt catch. I can’t recall with mine but did it come with a replacement bolt catch spring? Mine works pretty well but I learned from using the Kriss version of the bolt catch on another CMMG upper that a lighter bolt catch spring is needed for reliable LRBHO. Kriss offers them or you may cut a coil off the mil-spec spring.
My standard JP22 has never broken anything... however, it only gets 3000 rds annually, total under 12K. Multiple variables, in addition to the operating system; round count (stress), ammo selection and "depending on the trigger"... I have a Geissele HSNM under the JP22 with DMR springs and its been 100% reliable with S&B Club.How reliable are the JP rimfire firing pins? My Kriss DMK22c firing pin will break every 1000-2000 shots depending on the trigger I use. Thus I'm looking for a more reliable platform..
The old version was massively sensitive to ammo for accuracy (reliability was 100%). I've probably tested a couple hundred lots across various brands in my old one, and found maybe 2 that shot really well, the others on average are 3-4" at 100. It's far and away the most ammo picky gun I've ever owned, it's not even close. One lot of Tac 22, and one Lot of SK LR I've found shot really well out of it to 100, somewhere in the 1-1.5 MOA range, but everything else dozens of tests over the last few years, 3-4" is common at 100 or worse, it just throws huge flyers, even at 50yds. JP built this barreled upper as well. To be fair even JP admitted in email it was never designed for accuracy it was designed as an AR trainer. That said, I think anyone buying a $550-$750 rimfire barrel called "Supermatch" likely expects accuracy to exist.
This is a good example target from yesterday at the range. 100yds, 5-10 mph winds L-R, the groups on the left target are CCI STD, SK Pistol, SK Rifle, Wolf, and Eley Match. I often use the JP to shoot up partial boxes, or straggler lot boxes. The three 5rd groups on the right, are one of the "unicorn" lots that it likes, a lot of SK LR, the largest of which is 1.25". I find if frustrating when a gun performs this poorly, so if I take the JP 22 I know to bring a couple boxes of the "unicorn" ammo to at least get some good groups in at the end of the day. I must have been asking for punishment yesterday cause I also took my MCX out, which I doubt could hit a dinner plate at 200yds with any ammo, yet SIG says meets their 3rd 4MOA std......that they evidently test at 25yds.

I've tested probably at least. a dozen lots of SK LR, and the others end up looking like the target on the left. No idea what drives it, my only wild guess is that the gun is ridiculously picky on pressure/velocity to feed without damaging the bullets or bolt bouncing perhaps. If it was bolt bounce though you'd think softer loads would do better. I can't think of any other reason to see that much accuracy variation from lot to lot of the same ammo and it being this hard to find a lot/brand it likes. I see lot to lot variations in my CZ 457 or Volquartsen/10/22s, but it's much much smaller, once and awhile you get a horrible lot, but most lots of the better ammo shoot pretty similar. Also the lot based flyers are usually velocity related so you still get pretty good L/R groups just vertical flyers, but the JP tosses flyers everywhere. It's also not that this "unicorn" lot is just amazing in general cause it's just middle of the pack in my 457 for SK LR lots I've tested. In the past I've thought about trying different recoil spring rates to see if it impacted things, but honestly I just find the gun frustrating to shoot.
The new JP might be amazing, but they'd really have to prove it to me first that it's not crazy ammo picky, and it lives up to the marketing, esp. since it appears to use the same action/bolt setup. That said I do think their fully built rifles seem to delivery better accuracy on average than just buying their barrels and doing an assembly. I've had several supermatch JP barrels built up and while they were all good, none of them were outstanding when compared to offerings like Bartlien/Krieger etc. but they are not far off in price.
