Magnetic Buffer Review

When it comes to AR parts, everyone makes something similar. That is what I thought until I heard of the magnetic recoil reducing buffer from Frytech. This is a mil-spec buffer tube that uses magnets to dampen recoil instead of the standard AR buffer weight. This system is currently available through Pamax Tactical.

I am almost always hesitant about products that claim to reduce recoil. At least if they aren’t a standard muzzle device. But since I had been watching Frytech experiment with these for some time, I thought I would give it a try. I understand the concept of using magnets, as do most 5th graders. When the magnetic fields oppose each other, the magnets push away from one another. This field is progressive, so the closer the magnets are pushed together, the more force they resist. This is used to dampen the recoil in the Frytech Pamax buffer. It also allows the buffer to work with various calibers and barrel lengths.

The Frytech buffer system includes a few parts. As it arrives, you get a mil-spec 6 position buffer tube, castle nut, and end plate. Inside the buffer tube is a short spring, more on that later, and the magnetic buffer weights. There is a cotter key installed though the front of the tube. It has a tag on it that says something like “remove before flight”, but really it says “Warning, Magnetic, Do Not Remove Pin.” So do not remove this pin until the Frytech buffer tube is installed on an AR type firearm. Then you can remove the pin. The pin keeps the spring and the magnets in the proper orientation. If the parts go flying, you can install the magnets wrong and then the buffer will not function correctly. So, install the buffer tube, then remove the pin, and then head out to the range.

Now that we are at the range, I will give you my first impressions. The first time I had the Frytech magnetic buffer out at the range, I took 3 different upper receivers along with a standard lower to compare it to the Frytech one. So shoot 10 rounds, install the same upper on Frytech buffered lower, shoot 10 more, etc. You could definitely tell the difference. It was more noticeable when going from the Frytech buffer and then back to a normal one. I then tried the other 2 uppers I had at the range. Same scenario and the same outcome, less felt recoil. Two of these were 5.56 and one was a 300 blackout.

The Frytech buffer ran without any flaws until I tried a piston upper with it. The next time at the range I took my VKTR 10.5 inch piston upper and the Frytech magnetic buffer. The Frytech buffer did not like this, it would short stroke sometimes. Since the VKTR piston upper is finely tuned to run with VKTR’s setup, this did not surprise me. I only note it because it is the only upper that did not work well. I fully believe that if the VKTR were adjustable, or had an adjustable gas system, I could have made it work with the Frytech buffer. So if you are installing the Frytech buffer on a finely tuned firearm, you may have to make some gas system adjustments. But after that, you will get the benefits of those magnets in the Frytech system.

Since I wanted some real data on the Frytech buffer, I found my Mantis X10 and used it. When it comes to stuff like the Frytech buffer and claims of reduced recoil, I needed some actual data. So again, off to the range with an upper, two lowers, and the Mantis. I was able to get the data I was looking for. As you can see in the photos, all 4 of the metrics were reduced. Some by a pretty good margin. I now have data to show you, the reader, that the Frytech magnetic buffer is the real deal.

Because of all the testing, I ran the Frytech magnetic buffer with a bunch of different uppers. I definitely could tell that “magnetic” difference. I like this thing. I did notice a small, non-important hitch with it though. When cycling the bolt manually and slowly, the bolt wouldn’t always close on a new round. So I finally got to use that forward assist thingy to push the first round into battery. If you let the bolt release like you are supposed to, this doesn’t happen. Just thought I would remind people to let the bolt slam down instead of easy. This is also the reason the Frytech system has a short flat wound recoil spring in it. It is to help drive the bolt that little extra distance into battery. So did I mention the buffer uses magnets? Because of this, it likes to pick up allen wrenches off of my desk. They stick to the buffer tube. This could be a benefit, as you won’t lose the wrench for adjusting your optic. I know these things are minor, but I figured they needed mentioning. Speaking of annoyances, that buffer spring twang you sometimes get in a normal AR system is essentially non-existent in the Frytech system. Imagine that, magnetic waves are quieter than springs. Hmmmm, it is almost like they don’t make contact with anything. As I mentioned earlier, the Frytech magnetic buffer works. I really like the reduced recoil impulse, and it is softer feeling because of the way the magnets progressively slow the recoil down. The tube is also not some cheap imported tube, it is of nice quality and has the Frytech/Pamax logo etched onto it.

If you are looking for something to reduce felt recoil and have a softer shooting firearm, the Frytech Magnetic Buffer might be it. It definitely does what it says it will, it reduces recoil, as the data shows. Is it for everyone? No, but maybe it should be. It is especially good for people that are recoil adverse or those wanting to get the best performance out of their firearm. Head over to Pamax Tactical and check out the Frytech Magnetic Buffer System. I’m sure there are more magnetic things to come from these guys.

SLx RS-10R Review

Primary Arms has come out with their new SLx RS-10R. This is an updated version of the original RS-10 reflex style red dot. One of the big complaints about the original was the mounting footprint it used. Well, the SLx RS-10R has fixed that issue.

As with the original, the SLx RS-10R is packed with features. More important than all of those is the “R” designation at the end of the model number. That “R” stands for RMR. I don't think Primary Arms can say it, but we can. What that means for you is that the RS-10R now uses a RMR footprint. Or a Holosun 407C/507C footprint since they are essentially the same. The only drawback to using the RMR footprint is that the RS-10R now uses the smaller cr1632 battery instead of a cr2032. But through some magic, you still get 25k-50k hours of battery life.

Now back to the rest of the specifications. The RS-10R runs a 3 moa dot. I find the dot size to be a good compromise, no matter if you mount it on a pistol or rifle. It has 11 brightness settings. Of which, the bottom 2 are night vision compatible. To adjust the brightness, the RS-10R has soft touch buttons on the left side. When you reach the highest brightness setting, the dot will flash so you know when the limit has been reached. You also don't have to worry about turning the RS-10R on or off. It uses Primary Arms’ “Autolive” technology. This tech automatically turns the optic off when it is stationary and then on when it senses movement. Worth noting is the RS-10R has 1 moa click adjustments that uses a flathead to adjust. One can even use the rim of a spent case to adjust it, which I have done before. No trying to find the correct allen wrench. These clicks are tiny, but way better than no clicks at all.

Window size in these small red dots can be hard to understand sometimes. Manufactures spec the window size out, but it doesn't take into account if it is rounded or squared. Or where it is rounded and squared. I recommended looking through them to see if you like the window shape. Even though the RS-10R doesn't have a huge window, it is very well shaped to pick up the dot easily. Primary Arms specifies it as 23x19mm. I really like the shape. It is easy for me to see. Other people who I asked about it said the same thing, it's easy to find the dot. Primary Arms also fixed the refresh problem on the RS-10R. The original RS-10 would “galaxy” out because the refresh rate was too slow. The RS-10R does not have this problem. The dot stays consistent when moved and doesn't flash.

The SLx RS-10R uses an aluminum housing. They use 7075 aluminum which is a little stronger than the commonly used 6061. I like how the housing sticks out farther than the lens, giving it a little more protection from drops. One drawback to the RS-10R's construction is the higher deck height of the mounting surface. It sits higher up than some red dots. This doesn't hurt anything, but you do notice it when installing taller iron sights.

I ended up mounting the RS-10R on the Fusion XF-Pro. The XF-Pro uses a mounting plate system. This leads to you noticing the RS-10R’s deck height even more. It didn’t bother anything and I can pick up the dot easily. The dot on the RS-10R is pretty clear, even with my astigmatism. What I really like about the RS-10R, besides being an RMR footprint, is the window. For some reason I just pick the dot up quickly with the way the window is shaped. I am glad Primary Arms updated the RS-10 to an RMR footprint and fixed the refresh problems. It performs great.

I know there are a million reflex pistol red dots on the market now, but the Primary Arms SLx RS-10R is a great option. You get a lifetime warranty. It has a side-loading battery with their “Autolive” on/off function. Plus it now features that RMR footprint everyone was asking for. If you are in the market for a pistol red dot, definitely go check out the new SLx RS-10R.
