No one said his build sucked. It's just that "the jack" isn't actually anything special.

Don't be mad bro. It's just funny that you're saying your build is comparable to the Jack. It is too... in the sense that its an AR with a rail.

It's a geissele (sp?) rail.

I like the Jack's paint job, everything else seems like it could be done cheaper yourself (which the op demonstrated). if the have the dough that's cool, seems unremarkable though.

Cheaper? Maybe but you wouldn't get the quality parts that come with this rifle. For instance, I want to order a 14.5 inch barrel with pinned comp, mid length gas system from Daniel defense using their 12 inch MFR rail. I know I can build this upper cheaper with rails like the one posted by the OP, but it won't be as nice or as light. If I wanted the paint job and the $200 training certificate; I would have definitely hunted a Jack down. I'd be Jack'd.

The geissele handguard is awesome. It comes with a large extended barrel nut copied from the HK 416 design that the rail slides over for very tight, repeatable lockup.

I think the length used on the Jack is custom. Geissele MKII come in 13 and 15 inch lengths, I believe that is a 14 inch. Good luck finding one in this market, I've been looking ;(

I have a 14" middy barrel and BCM 1.0 comp waiting to go on a vltor upper, but of course I don't have a BCG or the handguard yet. I'm not paying nutty prices for a BCG.

I shoot a carbine gased, bushmaster upper 16" and has a pinned, yes pinned '74 style brake, with some israeli made quad rail, plane jane m4 style stock and JD lower, milspec trigger, BUIS and eoetch. I'm not very fancy and I probably can't tell the difference between a jack carbine and a $~2000 ar rifle. someday

I doubt that. My father (served in the marines) argued that my fancy ARs (specifically my SR15 upper+triple tap) weren't much different than his RAW (a colt with standard handguards and 16 inch barrel with an A2). He changed his tune immediately after shooting mine as he was actually able to double tap the 100 yard gong at Angeles consistently. He still laughed at my 10 rounders+bullet button though.

according to the vid i believe it's a geissele rail. it is a nice one, i would have liked it even more if it was a 12" instead of a 10"....that's what she said....lol

I made a Jack before BCM even announced the Jack!

I just don't have the cool Geissele trigger.

You can't go wrong with the 13 inch MK1. No other handguard, even LWRCI's SPR, feels better in my hand.

I know you know what you're missing but the concept is incomplete without an offset weapon light, combo muzzlebrake and flash hider, a pistol grip that's at a lower angle for ergonomic "tactical" shooting, and a stock with a wider cheek rest. Really the only thing in common with the Jack is a slick rail with attachable rail sections and backup sights which, a lot of people already have.

Not mad at all like i said its a build to my style and to prove to new shooters a similar build can be done with other components for less
Im sure some feel powerful at belitting others on the internet. Just like the military everything is done on a budget.

Yes im a lefty but have switched the upper to aero precision.
Other parts are still being added like i said build in progress
But notneveryone reads the whole post before commenting

So what you're saying is, that "the jack" actually isn't anything special since nothing you just described makes it one bit better than what someone can build on their own?

lol, they look nothing alike, but if yours does look comparable to the Jack AR, then I guess I also have 3 Jack's which were built before the actual Jack was released...

You didn't build a "similar" AR. You built another AR entirely and I am in no way belittling you. Relax buddy, I never meant to hurt your feelings. I simply disagreed with you passing your rifle as a comparable build to the Jack.

Lol. I can't wait for someone and some point in my life talking about a guy named jack riding a horse to bust that one out. I might have to wait a life time but I vow now to use that line
