JP Enterprises takedown pin

AR/M4 AR General Discussion

I’ve got a couple rifles with some wiggle/slop. I haven’t done anything to reduce it and didn’t want to use an accuwedge. But does anyone have experience with the JP Enterprises takedown pin? Does it work as advertised? Is it worth it?

Does it work? Yes. Do i like to use a wrench to take down my rifle, no. Is it worth it not in my opinion. JP makes great stuff and I have given them plenty of my money but this product I do not think is worth it.

A tight fit between the upper and lower has nothing to do with accuracy. What does the JP advertisement say it’d do?

While developing, and subsequent marketing the BAD-EPS (I was a Battle Arms partner, and co-inventor of the BAD-EPS), this topic was extensively discussed. Not only does the tight fit serve no real purpose (making people feel the rifle is high quality is not a real purpose), the tight fit now may require a tool or a bullet to push the pin in, or sometimes the user buys take down pins with over sized pin head to make pulling it easier, but these pins interfere with the ambi selector’s right lever.

If it really bothers you, don’t let it, it’s a non-issue :slight_smile:

“or sometimes the user buys take down pins with over sized pin head to make pulling it easier, but these pins interfere with the ambi selector’s right lever”

I know the pins you are talking about but the B.A.D pins don’t run interference.

Yep, I had a set of those oversize/EZ Pull pins - someone gave them to me, and now i know why. They didn’t stay on for more than a week. Being lefty made it even worse! I have BAD enhanced pins on every lower, except my pistol. I gave the EZ Pulls away with an upper I sold ;).

Re the wiggle - same as others stated, doesn’t affect accuracy, but it does bother some people. JP pin seemed overpriced to me, and also didn’t want to need wrench to break it down. One of my lowers has a tension screw, seems to work ok. Other options are an oring on the front pivot point, which works very well, but cuts often so buy a bag of 50 or 100. Another option is to use 3M Super 33 electrical tape (tad thicker than std. electrical tape) and put a sliver on the lower, and it takes up some slack. I’ve tried it and it works very well, actually - better than any of the other solutions I’ve seen.

I’ve scrapped that idea. I have no desire to use any tools to take down my rifles. I’ll live with the wiggle.

Right :slight_smile: The BAD-EPS, other than cost (billet construction, designed and manufactured in the US, no way around increased cost), has no compromises. A tight fit that’s a result of mix and match upper and lower receivers can happen, but when it’s by design (matched upper and lower, and give them a super tight fit to give unknowing customers the impression that tighter is better), the manufacturer isn’t doing anyone a favor, and in my opinion, is only helping to make this misunderstanding/misconception linger.

It makes no sense to me when it’s made to be super tight:

  1. User can’t break open the weapon without tools (a bullet is a tool, someone on TOS tried to argue otherwise. If it’s not a part of your body, it’s a tool!)
  2. User buys pins with large pin heads to mitigate the problem, which the manufacturer created
  3. This “solution” to the problem which the manufacturer created produces another problem, namely, interference to the ambi selector’s lever
  4. Profit? Yes, to the oversized pins makers, which are dumb ideas to begin with, because by solving a problem, it creates another, what’s the point?
