What is the Raider compatible with?
The MP17 RAIDER is compatible with the Sig Sauer® M17/M18/P320™ series full size, compact, X-five™, X-five™ Legion, VTAC, and Tac Ops™ versions.
It works with 9mm Luger, .40S&W, and .357 Sig models but IS NOT compatible with suppressor height sights or with .45 ACP models.
The Raider DOES NOT WORK with any other pistol make or model than what is listed above.
It WILL NOT work with M17/18 manual safety. You need to install a safety delete pin for the FCU to drop in.
Modifying the Raider chassis in any way (including but not limited to, optic mount chop or removing manual safety notches) will void the lifetime warranty.
My M17 has a manual safety, how do I install the FCU into the Raider?
We recommend that you install the manual safety delete pin from Sig. This pin will allow you to convert your FCU to one without the manual safety.
Modifying the Raider to fit the manual safety levers voids the warranty.
We highly recommend you do not modify the chassis in any way.
Do aftermarket P320 magazines work with the Flux Raider?
Yes, many aftermarket magazines do feed but some may not drop free easily from the magwells.
Aftermarket magazines tolerances vary widely and can have a very tight fit. We always recommend you use Sig P320 factory magazines as the Raider is designed around those tolerances.
It does not work with 15 round magazines.
What happens if I had a product in my cart but by the time I checked out it says it is no longer available or if I missed the restock altogether?
Unfortunately, due to a polymer shortage we have not been able to make large enough batches of our products to satisfy demand. We are working as hard as we can on sourcing more material to make more products. This results in Raiders selling out in less than a minute every time we restock.
Having the item in your cart does not reserve the product. The product is only reserved once the order has gone through and you have received your order number.
We also have seen that some people who use autofill and or apple pay have been able to checkout within 10-15 seconds. Manually inputting your information does take longer and could lead to you missing out on the restock.
This should not be an issue in the near future once we are able to manufacture larger quantities of our products.
I did not receive an email notification for the latest restock of the product I wanted, what do I do to make sure I am on the notification list?
We are now using a newsletter to let you now of the exact dates and times of our restocks. This is a subscription and you will receive every restock notification for all our products when they happen. No need to sign up again and once you have made an order of the product you want you can unsubscribe at any time.
You can signup for the newsletter on the homepage.
Why don’t you do backorders or pre-sales on your products?
This is a question we get a lot and we will try to explain it the best we can. Right now we are experiencing a polymer shortage and we have not been able to get our parts made in the quantities we once could. We are looking into all options open to us to get past this hurdle. But because of this issue we are staying away from taking pre orders or backorders because we would have no idea of how long it would take to fulfill your order.
We also used to do preorders and it took us almost a year and a half to get out of that hole. We don’t want to take your money unless we have product that we can ship to you in a timely manner.
When will the Raider Holster be available?
We are currently working on the Raider holster and are wanting to have it available sometime next year. The old MP17 holster was not compatible with the Raider so we had to start from the ground up on a better holster that would work for both left and right handed shooters.
Are pistol braces legal?
Pistol braces are legal.
The Flux pistol brace is neither designed nor intended to be shouldered. Unlike a stock, the brace’s unusual thin shape is designed to curve around the users forearm and has no texture on the back for grip.
As a company, we do not offer legal advice. We are not responsible for any future legislation made regarding pistol braces.
It is your responsibility to know and comply with all local, state, and federal laws.
We do not ship to California, New York, New Jersey, Connecticut, or Massachusetts unless you are active LE/MIL. We do not ship outside the United States.
Is the flashmag/spare mag carrier a vertical grip?
No. The flashmag is designed and intended as a spare mag carrier not as a vertical grip.
There is no designed texture for gripping. Furthermore it is specifically designed so you cannot wrap your thumb around it like a vertical grip. There are multiple other spare mag carriers on pistols on the market.
As a company, we do not offer legal advice. It is your responsibility to comply with all local, state, and federal laws.
Do we offer an LE or Military/Veteran discount?
Hell yes we do! We also offer department and unit pricing. Send us a copy of your credentials or email us from your department/work email for the individual discount code or send us an email request for more information on unit/department sales to [email protected] We will not retroactively apply discounts after an order is placed!
Can you holster the FLASHMAG?
Yes, we currently have a holster for the Flashmag but due to manufacturing issues it is taking longer to get back to making them.
Will the FLASHMAG hold other lights?
No, but we do have the Flashmag Rail that will fit most handgun lights and lasers. (Patent Pending)

You can’t use the brace along with a backstrap on any glock.
We don’t recommend stippling where the brace comes in contact with the Glock but it’s up to you. Fitment is very tight and could damage stippling.
Some extended slide releases will not work with our products.
Will you make models for other pistols?
Yes, we’ve got a lot in the works!
What lights does the Flux Brace work with?
Most Inforce®, Surefire®, and Streamlight lights are compatible. We’re currently compiling a list of compatible lights. If you’re unsure your light will work first check rail clearance before installing.
We are not aware of any lights/lasers that do not work with the Flux Brace.
Is there an FDE version?
Sorry, not currently.
The brace currently only works with our holsters, but other companies are currently working on light compatible holsters.
Does it work with the 6-Second Mount?
No, sorry, we tried. We are working on our own non-reciprocating mount.
