    I have a how to for exactly this if you look way back. Just search it.

    Yup pretty much this.

    Yes, I had to custom mount the UBR by drilling and tapping a mount with a screw in the rear of the buffer tube. It actually didn't take that long. There were a few fitment steps other than that, but that was the main challenge - not that it was much of a challenge. In this thread further back I wrote up how to custom mount the UBR to the KJW M4, however after reading through this thread most of these questions have been answered 2 -3 times in this thread.

    Eh you might have to file down certain parts of a standard KAC style 7" RIS. For the best effect, I would purchase a free float RIS with a proprietary barrel nut. That way you know it will fit. However, this doesn't fit some rifle "kit" looks if you're going for a dated era. I just wanted to let you all know that the serialized M4 still lives. I got this rifle way back on page (insert low page number here!) and its still a trooper. This was back when there was only one KJW m4, the full length M4 barrel type, and you had to machine your own 10.5"! My 00075.

    Its ACM, I even wrote up a HOW-TO Guide for installing it perfectly I think it was a page ago, maybe 2 pages back in this thread. Go check it out if you're interested. The ACM UBR is $70 shipped from T-Tiger on ASF, and the installation is more or less simple. It requires removal of the old tube, tapping of the rear cap, and installation of the new tube. That's about it. Took me 30-40 minutes in total, which included fiddling around with what to do, etc.

    I partially finished a build of mine today. The only thing that needs to come in is the Surefire M600c Scout Light and Surefire M76 Scout Light Mount. They're not too important for the actual gun though.

    I can't edit my post anymore, so I'll just post again... I just finished modding my ACM UBR. It was really easy. Thanks to Rookie Ab for helping me out with this and giving me some great ideas this week! This guide works well for all UBR's made to work with AEG's (AEG type buffer tubes), if you have one thats meant for a gas blow back rifle (has threads on the buffer) read the extra step. 1.) Unscrew the grub screw from the bottom of your original stock tube, after removing the stock you had on the tube beforehand. Also, at the time remember to remove the buffer and buffer spring from your buffer tube. 2.) Unscrew the rear cap from the stock tube. If you're is stuck, try using some Vice Grips and then turn them while they're clamped on to the cap. This should give you the friction you need and is way better than using some ridiculously big flat head screwdriver on that enormous cap. Once you've gotten that off, slide off your old stock tube which should expose the brass inner buffer tube unique to only KJW's. GBBR Threaded Buffer Tube EXTRA STEP: If you've got a GBBR UBR, you're going to need to wrap the brass buffer tube in some kind of heavy duty tape in order to beef up outer diameter. Since you can't use the UBR buffer tube, you're going to need to translate the UBR parts onto the original KJW buffer. I have not done this so I don't know how, but you can PM "Rookie Ab", as he has utilized this method. 3.) Now that you're ready to slide on the UBR buffer tube, you'll realize if you do this, there is a gap between the buffer and the receiver. This can be covered up in some electrical tape, or any other black tape. I used Gorilla Black Duct Tape, and it worked just fine. Keep test fitting the tube to make sure the tape doesn't stop the tube from coming all the way forward, and to see if you've covered up the gap enough. 4.) This is the fun part. Take a #8 or 5mm drill bit. Screw the end cap onto your brass insert WITHOUT THE UBR TUBE ON IT (duh, you can't!). Once its on nice and tight (its not coming off again baby, better make sure its tight) place the UBR buffer tube over the end cap and and brass buffer tube. Put the #8/5mm drill bit onto your favorite powerdrill and use the hole from the UBR buffer as a guide and drill through the end cap. 5.) After you've drilled the hole, remove the UBR buffer tube, exposing the brass buffer tube, and take your handy dandy tapping tool, and tap an M6 x 1 thread into the hole you've made. You have now made the correct threading for the screw you need to insert into the back of the UBR to hold it in place. 6.) Take your M6 x 0.75" long black screw (with one of those angled heads.. forgot the name of them right now) and screw it through the UBR buffer tube, and into the now tapped end cap that is sitting on your brass buffer tube. It should be super sturdy now, and even sturdier after you screw in the screws that hold the cheek piece over the UBR buffer tube. 7.) Slide the UBR stock onto the UBR buffer tube system, and bam, you're done! Took me about 35 minutes! Pics later.

    Lol, yeah I have a very good idea about what I'm going to do this evening and tomorrow to get it all working. Thanks for all the info. I'll post up a Co-DIY that will give both of us credit maybe at the end of the weekend or something.

    PM'd you for ideas.

    Well, since no one else really seems to know how to mod a UBR to a KJW m4, I will take the stand. I just ordered an ACM UBR through T-Tiger on ASF, and when it comes I will do a full HOW-TO on modding a UBR (AEG Type) for your KJW m4. I was frustrated that no one had made a DIY for it, and I'm sure many others have been before me. However, hopefully by next week I will have a full how-to for this application.

    Has anyone found a guide or just knows how to install the Magpul UBR (PTS, NON-WA) onto the KJW m4? I'd really like to put one on my build, but I just don't want to risk $170 to a stock that won't work.

    For those of you interested in the DD rails that use the Lite or RIS II proprietary barrel nut, the Daniel Defense Lite/RIS II Tool made for that different barrel nut is now $10 instead of $19, which is nice. I bought the tool for my real steel and I thought I'd pass on the info. T_hum, did you ever hear from Clare?

    I get 4 packs of Coleman for $8-9 at Dunhams. You guys are overpaying for Propane.
