The original Battle Arms Development Enhanced Bolt Catch, also known as the BAD-EBC, is a very popular aftermarket option for upgrading the Bolt Catch on an AR-15. Being that it was made from 8620 billet steel it also came with a $42 price tag. Battle Arms Development wanted to make a more affordable version of this popular item so they created the new BAD-EBC-IC. The “IC” stands for Investment Cast which is a much more budget conscious way of producing the Enhanced Bolt Catch.

If you still think Geissele only makes amazing triggers, you need to start thinking differently about Geissele. They have and still do make some of the best rails on the market but over that past few years they have added things like Armorers Tools, Optic Mounts, Charging Handles and now … the Maritime Bolt Catch. Think of the Maritime Bolt Catch as a bolt catch with a larger surface area and more aggressive texture. What this does that other aftermarket bolt catch’s don’t is it extends the controls closer to the index finger of a left handed shooter so they can manipulate the bolt catch with their index finger without taking their hand off the grip.

“The Geissele Maritime Bolt Catch is designed with the warfighter in mind and will work with any lower receiver designed to accept a mil-spec M16/M4 Carbine bolt catch. The increased surface area promotes ease of function when locking back the bolt or releasing the bolt after a magazine change. In addition, the extended controls add an increased functionality for left handed shooters who no longer have to break their grip to manipulate the bolt catch. Left handed shooters can easily reach the controls using the index finger of their left hand making magazine changes and locking the bolt back much more fast and efficient. Aggressive checkering covers the surface of the levers giving the Geissele Maritime Bolt Catch a textured surface that enables positive feedback to the shooters hand when being used with gloves or at night. Manufactured from properly heat treated 8620 steel and manganese phosphate coated, the Geissele Maritime Bolt Catch is intended to serve as an enhanced mil-spec replacement and assist in giving our warfighters overmatch capability with the M16/M4 carbine platform.”

Whether you’re a lefty or righty, there are benefits to be had here and coming from Geissele you know it will be top notch quality. Thankfully the price is extremely competitive with other aftermarket bolt catch’s with an MSRP of just $29. I’ve ordered a couple to try out and you can too at www.Geissele.com.

One of my absolute least favorite roll pins to install is the Bolt Catch Roll Pin. Its location makes it difficult to get at and being parallel to the side of the lower means if your punch slips off the roll pin when you hit it you are gonna scratch your new lower or your customers lower. Some companies have started making threaded bolt catch pins and holes to make life easier but you should never had to buy your new lower based on whether or not it has a threaded bolt catch hole or not. KAK Industry just introduced yesterday a new Bolt Catch Roll Pin Starter Punch that is extra long so you can hit it with a hammer behind the lower, is made of 304 Stainless Steel and features a recessed opening to hold the roll pin while you get it started. While Roll Pin Starter Punch’s are not a new invention by any means, I don’t remember ever seeing one specifically designed for the Bolt Catch Pin before so it really peaked my interest.

What’s even more impressive….the cost is just $10. Every AR builder should have the right tools to do the job and this is definitely one of them.

WE USED DURABLE RUST FREE 304 STAINLESS BUT KEPT THE DESIGN SIMPLE AND TO THE PRICE POINT LOW

ALL ROLL PINS ARE DIFFERENT BEFORE COMPRESSING, IF THEY ARE A LITTLE LOOSE IN THE TOOL USE A DAB OF GREASE IN THE POCKET TO HOLD IT TIGHT, IF IT’S A LITTLE TIGHT, DON’T WORRY, THE HOLE IN THE LOWER IS TIGHTER.. IT WILL RELEASE ONCE STARTED IN THE LOWER..

ONCE THE PIN IS STARTED USE YOUR NORMAL PUNCH TO DRIVE IT HOME AND GET THAT BUILD OUT TO THE RANGE AND BROKEN IN!!

OTHER ALTERNATIVE USES INCLUDE – CHOPSTICKS, SELF DEFENSE, OR MINE PROBING..

Every so often I run across a product that to me seems new but in reality its one I missed a long time ago and just didn’t know it existed. Last month, RECOIL published an online review of the Redi-Catch by Boonie Packer which seemed like a really cool new product but apparently its been around for some time. It allows you to lock back your bolt using the mag release button like the AXTS A-DAC system. If you want AXTS’ A-DAC system you have to buy a specific lower from a company that has paid to use that system. With the Redi-Catch you can virtually retrofit any AR lower to do the same thing using only a different magazine catch bar and an “S” shaped piece of Spring Wire.

I’ve said it probably 100 times before but its probably worth saying again, “I couldn’t care less about an ambi bolt release” from a right handed shooters perspective. When I insert a mag, I slap the paddle with my left hand and the bolt goes home like it should. However, I find a ton of value in the idea of an ambi Bolt HOLD for clearing malfunctions, etc. I really have no need to lock the bolt back while shooting unless I am clearing a malfunction. With an ambi Bolt HOLD a right hand shooter can keep their shooting hand in its firing position. The Redi-Catch covers two steps to clearing a malfunction all in one. By depressing the mag release you are dropping the mag and able to lock the bolt back at the same tim reducing the overall time it takes to clear that malfunction and get back into shooting steel…or bad guys, just depends on the activities for the day. 

The Redi-Catch can be purchased for just $34.95 on www.Redi-Mag.com

Forward Controls Design is getting ready to introduce their new ABC/R (Augmented Bolt Catch / Release) and I can’t wait to get on in and installed on one of my rifles. As you’ll see below the new ABC/R Bolt Catch is not flat like most Bolt Catch’s are. It features a slight angle not the bottom portion and a little bit steeper of an angle on the top portion. The photos show the ABC/R unfinished prototype (has not gone through deburring and tumbling). The retail units will be Melonited black and have a very high quality finish. Roger, the owner of Forward Controls Design (formerly of Battle Arms Development), explains why he wanted to redesign the standard bolt catch which you can read below.

It came from my dissatisfaction with factory bolt catch’s tiny, boot heel like lower paddle.  I’ve always deemed the top paddle to be of sufficient size, it’s the lower paddle the factory bolt catch, and most aftermarket bolt catches for that matter, fall short.

Forward Controls Design IBC:R 3

This shortcoming is amplified when there is a Norgon Ambi-Catch in place.  The Ambi-catch places its release paddle on the same vertical plane as the factory bolt catch bottom paddle, making the  bolt catch’s lower paddle even harder to use. With a gloved hand, it’s virtually impossible to tell them apart by feel.

Forward Controls Design IBC:R 3

The ABC/R has an enlarged top paddle, the lower 50% of the top paddle is canted at 5 degree, the upper 50% is canted at 10 degree.  The combined effect is the top paddle is easier to use, not solely based on its larger size, but because its angles.  When the bolt carrier is locked back, the canted top paddle is much easier for the palm or thumb to access.

The lower paddle of the ABC/R is canted at 10 degree.  With or without a Norgon Ambi-catch in place, accessibility has been vastly improved. The ABC/R’s angled lower paddle is on a separate vertical plane than the Ambi-Catch, making identification far more intuitive, both visually and by feel.

Forward Controls Design IBC:R 1

The notch immediately above the ABC/R’s lower paddle isn’t there by accident.  As you run your finger down the bolt catch towards the lower paddle, the notch is meant to give you tactile feedback “the top portion of the bolt catch is ending, you’re about to approach the lower paddle”

Forward Controls Design IBC:R 4

The lightening cuts on the ABC/R are there to make its weight as close to the factory weight as possible (0.445oz vs. 0.401oz), the ABC/R isn’t meant to be a lightweight component.

Right now the best place to keep tabs on all of the new stuff coming out from Forward Controls Design in on their Facebook page. Roger even shows off some pics of the design process to explain how things progress, etc and is a pretty cool page to follow. Look for the new ABC/R to be released soon.

Its always nice to find an inexpensive upgrade for your AR that can actually make a difference in function, etc. Very soon, American Defense Mfg will be releasing their new Enhance Bolt Catch for purchase and it looks like a really nice option that won’t break the bank. It features a larger “Bolt Release” surface and the entire face of the Bolt Catch is textured as well. I just looked and these are listed on the ADM website already which is a good sign that they are close to having them available for sale. Purchase price will be just $16.99 at www.ADM-MFG.com.

**Coming Soon!** The ADM Enhanced Bolt Catch. This is a part compatible with all AR style lowers that use a milspec bolt catch. The enlarged release surface and more aggressive serrations provide the end user with a more positive and dependable part for manipulating the bolt in their rifle. This is the same bolt catch that will be standard on all our UICs, shown on a BCM forged lower receiver.

In the AR world there are lots of partially ambi receiver sets but that typically just means that they have an ambi bolt release lever. To me thats not really an ambi receiver because you’re still multiple other features that aren’t ambi. I know I’m obviously not the first to feel like that and I can guarantee you that is exactly what SI-Defense was thinking when they started designing their new Full Ambi Billet .308 Receiver Set.

One of the first things you’ll notice is that both sides of the lower receiver look exactly the same. The brain trust at SI-Defense did this on purpose to ensure your body gets used to doing the same exact thing whether you’re shooting with your right or left hand. These mirrored features include an Ambi Mag Release, Ambi Index Finger Grooves and a complete Bolt Catch Assembly on both sides giving you a true Ambi Bolt Hold function which is absolutely priceless when clearing malfunctions (I know you’ve heard me preach about that before).

Upon further inspection you’ll also see that they have also included a Pivot Pin Spring Housing on both sides of the lower receiver. That’s right! This new receiver set even offers an ambi Pivot Pin and Takedown Pin system which is something I don’t remember ever seeing before. A couple of other neat features are the Quick Release Dust Cover Assembly and a Threaded Forward Assist Pin Hole.

So as you can see, this is a very well thought out design that looks just as good. I’ve also heard there will be an AR-15 version of this available as well so keep an eye out for that. SI-Defense is currently taking pre-orders for this new Ambi .308 Billet Set. Head on over to their brand new website at www.SI-Defense.com or call 406-752-4253 to place your pre-order.

**The receiver set includes dust cover, ambi bolt catch, ambi mag release. Forward assist, takedown pins and ambi selector not included but are available for sale in the Parts and Accessories section of their web store.

I swear I had absolutely nothing to do with picking the components of the new Enhanced Ambi Accessories Combo Kit from Rainier Arms, but if you looked at some of my rifles you probably wouldn’t believe me. The components that make up this kit are some of the most popular accessories for AR-15 builds and not just because they are cool, these are high quality upgrades. The kit includes three accessories that I would say are absolutely the best in their field, the Rainier Arms RAPTOR ambi charging handle, the Battle Arms Development BAD-ASS ambi selector and the Norgon Ambi Catch magazine release. It also includes the Seekins Precision Enhanced Bolt Catch and Billet Mag Release. Instead of buying all of these accessories separately, you can purchase them all together and save yourself about $40 over the usual price. Check it out now at www.RainierArms.com.
