KAC UXR 4 origin

[SuperHog]

Doing a new build.

Anyone purchased the 13" KAC UXR 4 rail from Airsoft Store? I was about to order it on-line but the description does not say if it includes the shim kit or it is actually made in the USA. Its says KAC on the webstore but it also says DYTAC hong kong.

It's DYTac therefore made in HK

Thanks. I think will pick another Noveske NSR by Madbull to replace the DD rail. All of my Madbull rails fit perfectly. And the bonus ... real licensed trades.

Chances are these DYTAC are make in China. I bought an ACM one last year and all the holes were off and the screws stripped out on me. What a waste of $$$.

If it was real KAC it would be much more expensive than that.

I know that. Unfortunately the ACM stuff is hit and miss when it comes to fit and finish.

I bought almost all Madbull rails and never had an issue.

I just picked one up a little while ago, redicilously comfy. Ya, it comes with a shim kit, and it threads on very easily.

ACM stuff is hit and miss because that's not a brand name. Literally everything coming out of china can be called All China Made.

Dytac is a very reputable company

I guess the big question, where exactly is Dytac manufactured? I am also assuming that the rails are not legally licensed from KAC. I have also seen a few close up pics, but no trades on these rails.

Their country of origin isn't a mystery its right on their website.

To answer your original question - it doesn't come with shims but you can buy a 30 pack of .25mm shims here:

You may also need the install tool if you want to correctly torque it to spec. Alternatively a modified steel pipe would work.

Dytac's stuff - some of it is made in HK, some of it in China. But they do make rails that nobody else does - case in point the URX4 and URX3.1 series rails. They also made a really sweet Noveske Shooting Team rail.

If you've seen close-up photos of the Dytac URX4 rail and noticed that they don't have trademarks stamped on them, then you must know that the RS one circa 2013 Shot Show version (the one on which the Dytac one is based) also does not. Also, the latest generation of KAC's URX4 features integrated sling swivels on the 3 and 9o'clock positions, which are absent on Dytac's version (easily remedied via a Magpul RSA-QD) On a side note, the Dytac URX3.1 (now discontinued) is actually the only URX3.1 replica to feature engraved trademarks - something that no other clone has. Dytac's anodizing could be better though.

Madbull's stuff is good and I have a few of their rails but they aren't without issue:
DD MK18/M4A1 RIS II series of rails requires the use of washers to correctly tilt the rail straight (install on a King Arms receiver)
Noveske/SWS series quad-picatinny rails absolutely require barrel nut shims (which aren't included) to get the rail to line up correctly
All Madbull licensed rails do not have provisions to allow for the gas tube without modification. This is a personal beef of mine actually - why go into the trouble of making great rails but force users to sacrifice realism by blocking off the gas tube? (presumably to prevent users from using it on real steel - although this is easily remedied via a drill press so why they went into the trouble who knows)

Funny thing - I'm actually staring at an ACM NSR rail on my desk right now and not only does it fit the VFC receiver I'm installing it on, has correct trades, but it also features the correct Torx hardware that the RS one has. (Madbull's has hex). Minor details...

It's unfortunate that you had bad luck buying ACM rails from overseas or another retailer but we test them out on various receivers during our T&E process so you'll always get something that fits.

That is because under the license agreement, Madbull can not have their lower cost airsoft rails fit a RS. I guess that is why you don't sell Madbull.

Clones makers can allow a gas tube because it is a clone and don't pay a dime to the RS companies.

Newsflash - Madbull rails fit RS. Their barrel nuts are manufactured to such loose tolerances such that they fit both Metric and Imperial threads. As I said, about 3-5 minutes on a drill press or grinder is all it takes to remove the restrictions Madbull has put in place. The ACM NSR that I was talking about last night has the Keymod sections on the bottom with correct Keymod dimensions, something that the Madbull NSR rails lack. In my mind this makes it a better clone than the Madbull version.

If royalties and supporting RS companies - purchasing the real deal is always an option. Besides, if you want to ensure complete compatibility on your PTW (presumably) with your RS accessories AND support the RS companies, why not buy the real deal? You won't have to deal with blocked gas tubes, modified Keymod dimensions, unknown metallurgy metal, painted metal, etc. Conveniently One Shot Tactical is now a retailer on ASC.

Airsoft rails are just an inexpensive way for me to own and test-drive rails' aesthetics and ergonomics. If I like something enough, I'll go buy the real deal (as is the case with the various Geissele, VTAC, Fortis and KAC rails I have owned, and currently own). Because let's face it, an RS VTAC rail is $160 while the Madbull one is $120? The choice is clear. For other rails, it's a bit fuzzy as a RS KAC rail is upwards of $280 and understandably out of reach for many. For this - clones like the Dytac URX4 rail are the answer.

[SuperHog]

Very good explaination. Never looked at it from your point of view.

Guess you guys rather sell only products you use and feel good about.

Does the Dytac URX 4 have correct keymod dimensions?

[Stealth]

The spacing is right, the wall thickness is not. So most screw-down keymod accessories will work but not the polymer ones like the NSR rail panels.

Now whether or not this issue exists with the RS KAC URX4, I don't know.

Are you going to be selling the ACM NSR?

[Wilkie]

Mine actually came with 5 or 6 shims, but it sounds like it wasn't supposed to, lol.
