I couldn't get the JP to work in any of my AR308 Ma Ten's (Slash's work great) but I have a couple in AR15's that do a great job.
Only thing that is smoother on recoil is the Enidine but other issues arise like not locking back on empty.
Was it one of the early JP 308 versions? I ask because I believe the first run or two had the incorrect spring rate in them and they were more finicky on function.... I have one on a Maten 308 and it is flawless...
The early .308 ones were fine. It was the early .223 ones that had the .308 spring on them that were the "oops." Worked great on the .450 BM.![]()
Has anyone had any experiences with a SCS in a supressed 300 blackout? Does it make a difference in function also does it quiet the action down enough to make a difference?
I have a gun very similar to the one used in the TTAG review that NICETRY linked, and I'm happy to say that the JP SCS works very well running sub loads, either suppressed or unsuppressed. It's REALLY smooth, regardless. I have not yet had a chance to shoot supers through that gun.Has anyone had any experiences with a SCS in a supressed 300 blackout?

I have one in my maten. Makes charging it feel like the bolt carrier is gliding on ball bearings and the recoil impulse feels different, but in a good way. Last night I tried to swap out the spring with one of the ones I purchased from JP and I swear that they epoxied the fucking bolt in. I applied heat via a torch per the instructions to no avail. Just be advised that its a bear to swap springs on it if its something you want or need to do. That's my only complaint.
Not to hijack but what carriers are you all using with the SCS? Standard, op-mass, full-mass, m16, semi, semi-enhanced, really curious about the SCS and this thread gas helped.
Actually if you apply the correct amount of heat it's easy.... I've done it Atleast 5 times.... I put it in a vise...pad it.... Heat it slowly with a soldering iron torch attachment.... I apply heat evenly around it for a few minutes then apply some pressure to the screw while continuing to heat....... Eventually it will just turn.... 5-10 minute job max... If it doesn't turn with moderate pressure you haven't heated it up enough to break the loctite.
Thanks for the info. I'll give her another shot.
Does the SCS add a noticeable amount of weight?

but want to make sure it's really going to reduce recoil and help me get back on target quicker before I spend $130+
Does anyone have any experience with Tubb's flatwire as well as the JPSC? Reason asking is I use the Tubb's for increased resistance to hold lockup a little longer. Wondering if I can get the same effect with the JPSC heavy spring setup. 223 btw.

I have it and love it. It is a total waste of money and would buy it again and again. I can't really say much about the recoil pulse, I mean it is a .223. I just like it because it makes the rifle feel well put together. Someone said pulling back the bolt feels like racking a custom 1911 and I would agree on that point. In terms of any functional difference, I can't say there is any. I read somewhere that just stuffing the buffer tube with white graphite lube while achieve the same effect. I prefer the less mess approach.
Some people like to finish their AR's in different colors. I like to add the JP captured spring.
I would like to know the same, I always put Tubb AR recoil springs in my ARs because they last forever
