I needed this 2 weeks ago when I wrecked my barrel nut, but JP customer service was beyond impressive

Everyone at the range tells me that this handguard is the cats meow. The Signature Series on my AR15 and Ar10. Love them, looks super professional.

My boy Dustin did a more professional version of this than the one did a couple of years ago haha - only thing that I do different is that I tighten the jam nut locking screws in a cross pattern to maintain consistent pressure all the way around. It makes keeping the barrel centered in the guard much easier.

I have a Quick disconnect specifically for the purpose of rail alignment and use it on all of my builds. The problem with the JP system is that you would need to purchase the top Picatinny in order to do it. And if you don't plan on installing one then it's a rather expensive purchase just to get the thing lined up. I think the rail should come with a short top Picatinny designed specifically for just that purpose. To align the rail to the receiver. I mount Infrared Flashlights and other items to the sides and bottom of my rails but I never mount anything to the tops. So to have to spend anywhere from $60.00 to $84.00 just to get them aligned is a bit steep. But regardless, I have over a dozen of the JP Handguards and I do love them. I did machine a special plug that is a perfect fit into the primary barrel nut and steps to the gas tube passage in the receiver to keep the barrel nut aligned until the LocTite cures for 24 hours. And I don't do the final torque until the LocTite is cured. I will tighten to around 65Ft. Lbs. while curing then upon final assembly I loosen then retighten to 85Ft. Lbs. and I also use just a light coat of assembly grease between the Handguard and the Barrel Nuts.

Hello, Thanks for a great video. How do I adjust the gas block when the handrail covers the top tension screw please?

I just wish there were anti rotation tabs touching the upper. Only thing stopping it from backing off is the gas tube.

The jam nut presses the threads against each other, when you tighten it. It seems like it's floating still but it's locked in. It's a very unorthodox way of doing it though.

I’ve always been intrigued by this rail. The rigidity of it specifically. Question: wouldnt it be better to put a piece of top rail on, and then use a one piece scope mount to bridge the gap between the upper and the handguard in order to align the rail, versus eyeballing it?

No. Never bridge optics. As rigid as a lot of hand guards can be they’re still a separate piece that can move and shift your optic. Unless you have a monolithic upper you always want your optic mounted on the upper receiver only. That’s why they make cantilever mounts to give you a little extra room if the optics still needs to go further than the receiver would allow
@BenBelkin
@BenBelkin 3 жыл бұрын
@@Spoons7414 you misunderstood. I said to use an optic mount to align the handguard’s pic rail with the upper before tightening down the hand guard. Once aligned, the optic would go on the upper only.

Yes. Not everyone is will have one of our 12:00 rails, but if you do, you could align the tube using it just like you're saying.

Wouldnt you put anti-seize on the barrel retaining nut threads and not the outside? I believe the instructions say to put it on the threads. After hand tight, also supposed to let it set 24 hours so the red loctite sets up.

Just to correct my previous statement, I was thinking the threads were inside the barrel retaining nut. They are not, they are on the outside. I just finished installing my new JP h/g. These instructions helped, but the provided instructions are very clear. Love the new h/g!!

@headhunta_ty2029 does the amazon mlok rail have the same screw size and distance with the JP rail? I also modified magpul rail by adding another screw hole to match the JP rail. For me its just too much work. Fyi 9inch jp rail is about $69 magpul is $24. Thats just crazy

Are you referring to the Thermal Dissipator (heat sink)? If so, you're correct. That's an optional upgrade for our barrels.

I know most/all their uppers receivers are thermo fit just as BCM receivers how would this work with them...... I’m interested in running your handguard with my BCM upper..... and is in best to slow the locktite to set over night prior to installing the barrel?

​​@@DrGoyo626I'm thinking that's why they tell you to put the barrel nut on first, before putting the barrel in. Because I don't see how you're supposed to heat that area up, with the barrel nut covering it, and I can't see why the nut has to be put on first. You can set the barrel and then install the nut...

Ive been looking for a handguard with out the integral rails for my latest 308 build. I really loved the look of this one, but after seeing the way it mounts. Ive kind of lost interest. JP makes great products and Im a big fan. Just not a fan of the way this mounts. I guess my search for a handguard continues
