Here's an AR10 carbine, I must have...oh...20rds fired through it lol This AR10 is the model of many of our selector pictures, as it is the only AR receiver I have that I haven't painted :)

Thanks guys, it was a no expense spared build at the time, of course now I'd have to get a better scope to still qualify it as such, but I reckon a US Optics SN3 is still good enough :) Here it is before I got infected with the spray can sickness

It's compatible with AR15 style receiver, AR10 (Armalite), KAC SR-25 style receiver, basically any AR style receiver (caliber is immaterial) that uses the AR fire control group :)

Got it. I will find out if the shop can do it :)

You bet :) Many of our projects and product improvements are ideas that come from customers, and we make sure to thank them properly (not just with words) for their participation :D

Thank you Rob! We have a reputation for prompt communications, mostly because I'm an impatient guy and can't let things sit :) I called the shop about SS levers, we haven't gone into production yet, so we still have time to make a batch for the September run. Do you want brushed stainless, or just shiny stainless? 8)

This was built to replace my Remington 700 in an AICS chassis as a precision rig, I'm not a fan of manual loading anything :) Noveske 18" barrel, Daniel Defense Lite Rail 14.0 (out of production since), Surefire brake, LaRue SPR mount, US Optics SN3, KAC 300M rear BUIS, Troy front BUIS, TNVC SAR (for mounting a red dot sight), Magpul PRS stock (for AR15, not for AR10, the AR10 PRS is almost useless due to the location of its cheek piece, it's too far back) It's missing our selector, I haven't got around to putting one there yet :P

Thank you Johnny!

As a policy, owners of our selectors have the option to exchange their levers for something that may work better for them, irrespective of place of purchase. Over the years we've had hundreds of levers that were not returned because folks either forgot, or decided to keep them (I received emails from them stating they decided to keep them even though they knew they were supposed to return them). Unfortunately, the free lever exchange program ran its course. The cost of exchanging the lever covers shipping and a bit of our cost, we're not making money by exchanging levers with customers, we're not even breaking even lol.

We designed our selector groove with tall shoulders, so the selector cannot be backed out when it's rotated out of the detent holes. If you do a search on "AR selector install", you will see that some folks advocate that you rotate the selector to 45 degrees, and from there you can push it out the side, all without removing the pistol grip, detent spring and detent. We can hardly argue this is a good attribute. In the picture below the tall shoulders to either side of the detent start to make sense: There is no way to push the selector out, short of removing the pistol grip, detent and detent spring. The deeper groove on our selector, among other things, was done to ensure minimal lateral movement. We are bringing the depth of the detent groove up a little to ensure the detent spring retains more its spring pressure against the detent, at the same time we're also keeping the tall shoulders to prevent the detent from jumping over the groove. These changes will make their debut on the current 45 degree, 90 degree semi auto selectors, and the CASS-3P, SA (semi auto) selectors in September. To be sure, since the lack of spring tension can and does happen with other MIM selectors, and over all, fewer than 0.05% of the users of our selectors experience this, not all the mushy feel will be addressed by this, but we're eliminating this anyway :p

regarding the receiver. The receiver will not allow the detent to go through the detent hole. On my receiver, the detent protrudes about half way and is stopped. If your receiver's detent hole isn't drilled properly, it will stop the detent from reaching up as far as it should be allowed to, the detent bottoms out and can only go so far, where no amount of spring tension would help the mushy/spongy feel. On such receivers, a detent that's not protruding into the selector hole in enough length is enough to engage the factory selector that has a shallow detent groove. Our detent groove is deeper to prevent the selector from being backed out when rotated out of the detent holes, and this would cause the mushy feel issue.

Cast selectors are not precision machined like ours, this can be a bad thing (mostly not so good, but easily overlooked) and good (just one). When a cast selector is installed, you can most likely move it side to side inside the receiver. The reason for this is the detent holes are much bigger than the detent (ours are 0.005 larger in diameter than the detent itself), there's quite a bit of slack. The side to side movement doesn't hinder the operation of the weapon. It can serve to accommodate out of spec detent/detent spring housing if it's drilled not where it's supposed to be drilled, e.g. a little bit too forward toward the muzzle, a little bit more toward the rear, a little to the left or right. Because of the slack, the detent usually has no issue seating in its general area. Our detent holes are far more precise (0.005 larger than the detent). In a receiver where the detent/detent spring hole on the receiver isn't drilled to spec, the detent may not seat squarely in the detent holes on the selector. When the detent isn't fully seated, it then can be more easily rotated out of Fire/Safe. While spring tension (length of the detent spring, the depth of the detent spring hole inside the pistol grip) can play a part, chief among the reasons our selector can feel loose has to do with the receiver. We're investigating making our selectors more compatible with this aspect of the tolerance issues on the receiver, we could make the detent holes less precise, and have more side to side movement as a result. In PIP1, we made the selector flat area diameter smaller to accommodate triggers that are not of USGI specs. In PIP2, we increased the width of this flat area to accommodate slightly out of spec receivers when a DMR trigger is in use. It's about impossible to make it fit every receiver made, and receivers that haven't even been brought to market, the tolerance issues will be with us forever.

We have received couple of questions regarding our selector's seemingly ease to flick out of Fire/Safe. We hold very tight tolerance on our selectors, as anyone knows, this can't always be said of other parts on the AR, especially cast or plastic parts. The following are our findings re: detent spring tension, pistol grip and their effect on the perceived stiffness on the engagement/disengagement of the selector. Detent springs aren’t created equal, just the two I happened to have on hand are of slight different lengths. One of them is about 1 coils longer in length (though same number of coils). Pistols grips (USGI, Magpul MIAD, Tango Down Battle Grip, etc.) aren’t created equal. The part we are interested in is the depth of the detent spring housing/hole. With the same spring inserted in these three (USGI, Magpul, TD Battle Grip) grips, the spring seats deeper in the USGI than Magpul MIAD and TD Battle Grip, by about 2 coils. Can spring length make a significant difference? Depends on which spring and which grip are being used. A shorter spring inside a USGI grip will yield less spring pressure on the detent, than a longer spring inside a MIAD or TD Battle grip. I was able to test and verify this. A shorter spring inside a MIAD or TD Battle Grip doesn’t feel significantly different, but without precise instrument to measure the pressure, I’d say one can hardly feel the difference. The difference of a shorter spring + grip that seats the spring deeper, and a longer spring + a grip that seats the spring just right, is noticeable when the selector is rotated out of Fire/Safe. Short spring + USGI = sloppy feel, less positive click, easy to rotate out of position Longer spring + MIAD or TD Battle Grip = more force is required to rotate out of position.

This is a subject that comes up now and then, so we'll stick this here to serve as general information, as it applies not only to our own selectors, but all selectors. There is a gap between the underside of the selector lever and receiver wall. The extent of the gap is a matter of receiver thickness. We took measurements from couple of dozen receivers before deciding the length of the selector center. What it comes down to is the thickness of the receiver. The milspec thickness is .880 +.015 -.002, or .878 to .895. We based our selector axis off one of my Colt SP1s, which is 0.898 and on the thick side. Even within the same company, there are variations. This is a factory selector on an AR10 This is the prototype selected for production, after we've reworked the length of the selector center. The difference in amount of gap between the left and right is 0.01, the reference receiver is a Colt SP1. [img width=810 height=297]http://i75.photobucket.com/albums/i314/Duffypoo/Mod0protrusionsonColt1.jpg CASS-3P, M16 (picture taken before our patent paperwork was filed to mask the patent pending dovetail interface) [img width=810 height=850]http://i75.photobucket.com/albums/i314/Duffypoo/bothleversfromunderthereceiver.jpg Colt, Bushmaster Armalite, DPMS, LMT and KAC are all pretty well within specs. POF and another billet lowers are notably thicker, at 0.905 and 0.911, while Olympic Arms are notably thinner than specs. There's NO way to make a safety selector and have it fit flush with all brands of receivers, as mentioned, even within the same manufacturer there's slight changes. The same ambi selector that fits flush on a Bushmaster, LMT, and KAC will almost be too tight for a POF. With a standard, non-ambi selector, this isn't an issue. If you haven't noticed, the axis usually sticks out a little on the right side, while some don't. This can be a problem for ambi selectors, too much protrusion on either side, it won't be as low profile as can be, and the lever will pinch your finger when you rotate the lever from Safe to Fire while its extended in the "finger outside the trigger guard" position (this is actually somewhat unavoidable, we just try to minimize the pinching). There is no problem with the lever sticking out and not sitting flush (it will never be flush, the original Stoner design calls for a gap between the lever and the receiver, and for good reasons). In terms of rounds fired, eight M16 with our selectors had 100K rounds through them in less than four months without any failure. Semi auto selectors have far more rounds fired, as there are more semi auto selectors in the hands of users :)

With the new 45/90 degree compatible receivers available, and more from Spikes Tactical and AXTS already in production, we should elaborate on the 45 degree selector's development history. The 90 degree selector (what we deem, and therefore call legacy selector) is something of a mystery to us. We are hard pressed to think of tangible benefits to a 90 degree throw, other than requiring the shooter to be deliberate of his selector action, as the throw is longer than necessary. The long throw notwithstanding, it also introduced another problem: when the selector is set to Fire, the lever points straight down and creates interference with the trigger finger. With our semi auto ambidextrous selectors, we came up with levers of various geometry, length and thickness to reduce the interference, but it is impossible to get around it altogether. This is a design constraint, as it is based on the legacy 90 degree throw selector. There's typically no problem switching the weapon from Safe to Fire, the problem has to do with the reverse (switching from Fire to Safe), it will require the shooter to shift his grips. With an ambidextrous selector, the awkward motion is mitigated by the shooter's being able to use his trigger finger to manipulate the trigger side lever, but there is no denying the ergonomics of this arrangement are of dubious quality. For an M16, the ergonomics shortcomings are even worse. For decades, other platforms have had the short throw selectors. HK, SIG, Beretta, FN, and lesser known military rifles have had them since the 60s. The short throw arrangement certainly isn't new on these platforms. We made the short throw selector for the AR15 (and soon M16) platform. The result is fairly predictable: much faster selector manipulation, no shift in grips during lever manipulation from any direction, much reduced interference to the trigger finger. We did run into a problem: liability. At 45 degrees, the position indicator groove no longer points to Fire on a standard receiver (at 12 o'clock). We thought of everything possible to get around it, and in the end we had to make our 45 degree selector incompatible with existing receivers by pressing a stainless steel pin block into the selector center, to prevent its use on a standard receiver. The idea is that the short throw selector needs to be used on a properly marked receiver, the standard receiver's Fire marking is inadequate. Note on the stainless steel pin block: the sole function of the pin is so the 45 degree selector cannot be inserted into a non-45 degree compatible receiver. The removal of which will constitute unauthorized modification and void the warranty. We do not publicly or privately suggest or recommend such modification. The 45/90 degree compatible receivers are different in two areas: new Fire engraving at 68 degrees so the marking is suitable for both the 45 and 90 degree selector, and a notch cut in the left side of the receiver selector hole. This gives the receiver the unique ability to accept either the 45 or legacy 90 degree selector. Below is an AXTS forged, 45/90 compatible receiver. Note the 68 degree pictogram for Fire. The radiused gauge looking line between 68 and 90 degrees is an AXTS exclusive, though it is not needed. Here's one of the videos we posted of the 45 degree selector in action. Note the shooter's grip never moved during selector manipulation http://www.youtube.com/watch?v=LRkmt3Hhu0Y

Thanks Robocop :) If we do produce a version in stainless steel, I will send you one for coming up with the idea :)

Thanks Ray, we can certainly run a board special :) I will post details later today ;)

Hi Robocop, we have plans to offer levers in Cerakote options. Please email me at roger@battlearmsdevelopment.com and I will take care of it :) Re: stainless steel levers, we have not thought of offering the selectors or just the levers in stainless steel, as a company we're very open to suggestions, so we will look into it ;)

Hi guys, thank you much! We appreciate the opportunity to have a presence here :) We will populate our forums here with FAQs, and use it to share technical information, and answer questions related to our products. As with other boards, we would contribute what knowledge we have in non-Battle Arms related topics, we're here to be a part of a community, not just to showcase and sell things :) One of my AR10s was among the test platforms for our selector. Today many product pictures are still taken with the AR10 because it's the only receiver I haven't painted lol.

We did not have a booth at the SHOT show this year, but our selectors have been spotted in a few places: Remington, Mega Arms, LWRC, and TNVC :) We're developing a few more selectors: short throw M16 (0-45-45), IAR (safe-auto-semi), and CASS-3P (dovetailed lever attachment interface) in semi auto configuration. Coming soon are Cerakoted selectors. Ernie Bray at Red Creek Tactical is coating them for us. We're having the levers coated, and the selector centers, and the screws too :D

Hi guys, thank you for your kind words. Since late May's introduction, we've made a few modifications and introduced two more levers and an end cap. We're always listening to our customers and trying to find ways to make good kit better. In PIP1 (product improvement program), we made the selector flat's diameter smaller to accommodate triggers that don't adhere to factory specs, and started to include a high quality KNS stainless steel detent. The KNS detent is available to customers that bought our selectors between late May and early August (after which we started to include it) at no cost. We also introduced two additional modular levers at the time. In PIP2, we made the selector center's flat wider to allow the use of Geissele DMR trigger even if the user's receiver may be slightly out of spec. We introduced an end cap as well, which allows the selector to become a rapidly reversible (left lever only, or right lever only) and convertible (fully ambidextrous as designed, or single lever) selector. Next year, we will have FDE, OD and gun metal gray in Cerakote, which has better salt spray resistance, and will be even smoother than it already is. Also available are the 45 degree short throw, and M16 (CASS-3P, M16) selectors. 98Z5V, please email me roger@battlearmsdevelopment and I will send you a KNS stainless steel detent :) Thank you guys!
