Thank you Eric

Just got in my first two sets of these on Monday from Brownells. Wow what a difference a bit of length and nurling makes pulling the pins. The fit and finish is 100% flawless as all other Battle Arms products are. I just ordered six more sets to outfit the rest of the fleet as I feel these are a must have on a AR. Please make these for the MP15-22 as well. Not having to find a doohicky to push on a pin to take down is very nice. It amazes me how your products really simplify the AR.
Thanks Again,
Jason

Jason, thank you for your feedback!

As to MP 15-22, they do work. The only difference is the 15-22 receiver's take down pin spring/detent hole is next to the selector detent/spring hole, so the flat that's normally facing 1 o'clock will need to be rotated counter clockwise (with the pin head facing you) by 90 degrees, so the detent holes and groove of the ETP is facing 6 o'clock.

The flat is now facing 10 o'clock, not a very useful place for it to be, but there's still knurling on the rest of the pin head

We will be offering a version for receivers whose take down pin spring/detent hole is not parallel to the bore, this will orient the flat on the ETP to 1 o'clock

Awesome! Yes I tried the second set on one of the M&P's and realized this. They work but need a tweeking. Glad to hear you are going to make them.

No firm ETA at the moment, but not long now

got a set in today from rogtac. I like them. I'm upgrading all my rifles with these. good job guys.

Glad you like them!

I love these pins, just put a set into my current build and have a spare set awaiting install in my wifes gun.

Awesome! Have you tried them with gloves on?

Yes, was pretty damn cold when I went out last to shoot and was running the Camelback MaxNT (FROG) Gloves that the Marines issue and had no issue breaking down the rifle when splitting it up. These pins are absolutely amazing, especially when your rifle is right on spec limits and needs some work in.

Thanks for the feedback! Real field experiences are important to us, we can make improvements if any is required based on user input and experience

Could the slightly undersize pin diameter induce receiver wiggle/slop? I have quite a severe case of wiggle
and I am looking for causes.

Was the standard pins better? Less woble? I have installed a total of seven sets of these and notice no measurable difference in receiver to upper movement. I am curious if you have this with standard pins as well.

Posted: 2/18/2014 8:30:13 AM EDT

[#16]

In cases where the users perceived play when our pins have been installed, they were able to replicate this with factory pins.

Posted: 2/18/2014 6:23:56 PM EDT

[#17]

I just cant imagine these pins creating a wobble if the receivers fit good from the start. I'm no machinist but I just cant see that happening.

Posted: 2/19/2014 3:26:18 AM EDT

[#18]

Roger that. I don't have a comparison with standard pins. I will go the O-ring route.

There are variables at play other than the pins, which are rather minor parts of it. The loose fit won't affect accuracy, it might rattle a bit but it has no impact otherwise.

But it's damn annoying when it's excessive!

No doubt, especially when you expect it to be tight

Found an interesting video in this Thread about how to install the EPP's without removing your stock

Just in case that doesnt work, here is a hot link

Posted: 2/24/2014 10:27:22 AM EDT

[#23]

Yep after seeing how many people ask about it, I urged NSZ85 to make a video, it's far easier to show than it is to describe

Posted: 2/24/2014 10:50:51 AM EDT

[#24]

Sweet, I have 2 additional sets inbound to be installed later this week

Posted: 2/24/2014 11:16:32 AM EDT

[#25]

Awesome

Do you find them useful? In testing, we wanted to make sure the pins would be easier to use with gloves. Being we're not in a really cold part of the country, I still wear gloves all the time when I shoot and that was one of the design goals.

After they've been released, feedback from users indicated that in cold weather, with stiff and colt hands, gloved or not, all the little improvements we added to the pins really come in handy

I love mine, they will be a guaranteed install on all future builds and an upgrade to previous guns. I have a couple upper/lower combos that are right on spec or trying to be out so pins lock up super tight but with these I have never had an issue with them

Posted: 2/24/2014 11:45:44 AM EDT

[#27]

Thank you for your feedback, it does validates our reasoning for making the pins 0.0005 smaller in diameter. Not small enough to induce wobble and play, but just enough to make it more compatible with the myriad of uppers and lowers mix and match combinations out there.

Duffy, was just looking at my BAD EPS and noticed one of the springs has a slight bend to it at the end like it got caught on something. Will this have an effect on its operation? If anything it makes the spring ever so slightly longer. I was going to just purchase a set of springs and detents incase I send one into orbit but they're sold out on the website. If it won't effect operation I won't even worry about it.

Posted: 3/28/2014 8:43:22 AM EDT

[#29]

I've used slightly bent springs without ill effect, it's fine, don't worry about it

Posted: 3/28/2014 9:01:46 AM EDT

[#30]

Awesome. Thank you much!

Posted: 3/28/2014 11:42:59 AM EDT

[#31]

If you notice any degradation in performance or reliability (I don't think you will), I'll send you a replacement

Two new KNS detents and CSS springs are included in the retail EPS package, customers can use them or keep them around as spares, you probably have enough to go around

I pieced together a lpk for the build so no extras. I'm sure it will still work fine. Just wanted to be sure. Should be doing the build next week sometime.

Posted: 4/7/2014 4:42:31 PM EDT

Though not specifically designed for it, the EPS also works on the Smith & Wesson MP15-22. MP15-22 receiver is thicker and requires its own selector center.

The 0.030" extra length is absorbed by the MP15-22's thicker receiver, there's still enough of it protruding from the left side of the receiver to work well on it

I'm in the process of a midlife rebuild of my 9mm AR. This one has a NDS lower and a RRA upper, and has always required a mallet to drive the pins.

I swapped over to a set of these - much, much better fit! I can almost completely drive the rear pin by hand, and the front is perfect. A few hundred rounds should make the fit perfect.

These are rapidly becoming one of my must-have components, just like the BAD-ASS.

Thank you

Light weight version should be out this summer
