View Full Version : Addax GPU Side Charging Handle Upper

We are currently testing a side charging handle upper receiver on one of our Addax GPU builds.

The Side Charging Handle Upper is from American Spirit Arms and we have several more on the way from ASA built to our spec for our Gas Piston Uppers.

This Side Charging Upper has a non-reciprocating charing handle, and it is really fantastic idea over the standard top charging handle on a standard AR.

So far we have put close to 300 rounds through this upper in our testing, and we plan on testing the side charging handle upper receiver allot more.

If it passes more of our testing and full auto testing, we will be offering a side charging handle version of our Addax Gas Piston Upper.

Stay Tuned...:43:

Will you be selling just the side charging upper (plus bcg) too? I was always interested in one of those.

We will make a product announcement once we get them in.

Thanks,

Great work!

Thank you Sir.

I am happy to report that this upper is working out very well for us.

I have some tests to run next week in full auto with PWS in Idaho, and after this, we will make a final decision if we are going to use this upper in our Elite Series GPU's.

I was there, too. Man...those are some great pics, but they sure don't beat handling it in person. One word...SWEETNESS!:43: Thanks for letting us shoot it, Addax. Please keep in touch;)!

Oh yes, BTW, do you have a price?

I am currently working on this.

I am building a new model called the Elite Series, which I plan on using the ASA Side Charging handle upper and barrels from Sabre Defense.

I will also offer the Side Charging Upper as on option on all of the other series of GPU's we currently build as well.

These uppers retail at $375, and I am working on a bulk buy price, so I will let you guys know as soon as we are dong testing this upper and negotiating the price with ASA.

Thanks,
Chris

I'll warn you all now...

If you are familiar with the AR, beware of this type of side charging upper.
If you rack the bolt back and forget to manually return the charging handle to the forward position, then depress the bolt catcth to let the bolt forward, you will get one of these:

That's after 2 days of healing too.

With a normal AR, nothing happens if you rack the charging handle back, lock the bolt, then press the bolt catch to release the bolt.
The charging handle closes, but your finger will not be in it's path.

I remember seeing that battle wound ^ last time the side charging upper was brought up. I really like the idea of the upper, but would have to go with an ambi bolt release lower to avoid that.

Ouch.

Thankfully that has not happend to us during our testing.

We figured it out when we put the upper together that the charging handle should be pushed into the forward position before releasing the bolt, much like a FAL.

The Side Charging Handle addresses many of the complaints I have personally heard from users who do not like using the top charging handle.

The ASA Side Charger is a very nice system, and so far everyone who has had a chance to handle it loves it.

If this upper passes our testing, and we add it to our parts list, I will make sure to provide a little instruction guide for the side charger to help users avoid pinching their thumb.

I charged it a couple times, it seemed fairly basic and easy. I didn't get hurt. Then again, I was being very careful since it wasn't mine. But I really want one! Put me on the list for one of these, Addax! I've got cash in hand, so I'm good to go whenever you guys are.:43:

Chris still sells them as GPUs though I doubt his stock is good, but its worth a call if you are truly interested. As far as the side charging upper itself goes, ASA sells them. I bought one and love it, the top charging handle design that the AR uses feels so much less ergonomic and less comfortable to use now. With the side charger you can charge the weapon from the hip or from your shoulder easily and you can charge the weapon on the prone much easier as well. IMO a much better design than top charging AR.

Back from the dead... What ever happened to these?

We built a few Side Charger GPU's, and we still have a few more backorders to fill.

Due to all the buying frenzy that was occuring during the past 7 months, supply of the side charging uppers were non existent, and what I picked up, I built and sold very fast.

We just received a huge shipment of Side Charging uppers 2 weeks ago, and I decided to have them Cerakoted Black since I have been very impressed with the performance of Cerakote in a few other recent builds.

Plus they are equipped with Young Mfg. Full Auto Bolt Carrier Groups, so the upper with Cerakote and the chrome bolt carrier group is just slick.;)

I plan on catching up on my back orders over the the next month, and I am also releasing a small batch of our new ATAC Gas Piston Uppers with the Side Charger Upper option, which I have been working on the past week.:cool:

Stay tuned.

If you guys want a Side Charger ATAC GPU, send me an email, and I will get you added to the list we already started.

Thanks,
Chris

Basically we are building Gas Piston Uppers with a Side Charging Upper Receiver manufactured by ASA.

We are building some of our Mid-Length GPU's with the Side Charging Upper to fill our current backorders, and we are planning on building our new ATAC GPU's with the side charging upper receiver.

Shoot me an email, and if you want to know more details.

wasnt some modification needed to the bolt catch for these uppers? i remember talking to someone about this and as much as they loved it they had to slightly modify something to make it work smoothly

I supply a modified bolt catch with each of these uppers.

The top edge of the bolt catch I supply is machined so that there is no intereference with the charging handle when installed.

If you don't mod it the charging handle will be slightly obstructed. I ran with a regular bolt catch and ASA recommends just forcing it forward. It scratches the bolt catch a bit but it isn't hard to push the handle forward. I think Chris cuts off the top tip of the catch. I used one of Ken_BTC's extended bolt catches and I decided to just take a dremel with the sanding wheel attachment and shave it down. Works perfect and looks great. I got lazy refinishing it though and just used a sharpie. I think later on I went over it with Birchwood Casey's Super Black Pen, it doesn't look that bad because its only the top of the catch.

How easy is it to manually lock the bolt back if the bolt catch and charger are on the same side?

Same thing. On a regular catch you have that nub on the bottom, it is there on Chris' catch as well. I used Ken_BTC extended bolt catch so it is even easier for me. I just use the side of my trigger finger to push up on the extention.

I think my AR belongs here :D

so in other words its probably advisable to hold off on putting the stock catch in if you plan on running one of these uppers. dont know who else has had to remove one once its in but its not fun.

I would.

The modified catch will work with the Side Charger upper, and with a standard one. All I do is machine the first 2 lines off the top of the bolt catch.

Yes, we can use the Side Charging upper on the new ATAC GPU.

I am currently having some made for our new upper/piston system.

The first and only complaint I remember from some friends in Coronado who have been using the new FNSCAR is they hate the charging handle. Crawling around and shooting while laying sideways is the concern. Most of us normal folks may never shoot like that but.........an ar with a side charging handle is very similar. Just fyi something to think about.

That is why we offer both types (with the standard charging handle, and a limited run with the Side Charging Handle).

I have a few LE and Military customers who love the Side Charger, but it does take a little getting used to.

1) Unlike the SCAR the charging handle folds down very low profile and is locked in place
2) Unlike the SCAR the charging handle is non-recipricating so you cannot hit yourself with the charging handle while shooting the rifle (big complaint I hear with the rifle)
3) Unlike the SCAR the charging handle it is much closer to you so you have less chance of it getting near the ground and zero chance of getting hit with it in the prone.
