PianoBlack Posted January 16, 2010 Report Share Posted January 16, 2010 The ridge is a removable insert that you can swap with a flat insert. Â -Piano Quote Link to post Share on other sites

MunkyMo Posted January 18, 2010 Report Share Posted January 18, 2010 Sorry, I'm out of town on business for a short period. I had zero issues getting the Rail kit to fit. I removed the front sight post, and left the gas tube out, but it fits on just fine. Â I found the easiest way to mount it was to tighten the friction lock down some, but not all the way, then slip the rail kit on and turn to tighten, which should carry the friction lock with it and align your top rails. Turn to tightness, then put in the screws to set everything in place. It looks quite good to my eyes, there is a small portion of the outer barrel still showing, approx 1-1.5 inches from the rear of the flash hider to the beginning of the rail kit. An interesting side effect of the rail kit is an audible metal "twang" sound to be heard with it each shot. Â I'll be adding noveske MBUS and a Noveske flash suppressor soon as well.

WhiteHawksan Posted January 18, 2010 Report Share Posted January 18, 2010 just what I was thinking, Although I did notice that the G&P Troy Style BUIS are not actually correct to the Noveske Rifleworks N4 as the front sight the leaves bend outwards not round. Quote Link to post Share on other sites

PianoBlack Posted January 18, 2010 Report Share Posted January 18, 2010 How sturdy is the Low Profile Gas Block in holding together the original outer barrel? Thanks.  Since I haven't tightened down the screw all the way as I'm still waiting on a gas tube (You will need an AEG gas tube to use the 5KU gas block), it suffices as the compensator sleeve (B2) does most of the work holding the outer barrel sleeve (B4) onto the outer barrel (B6). At the rear of the outer barrel sleeve (B4) there is a threaded hole where a grub screw could be installed in order to tighten up the outer barrel sleeve (B4), but no grub screw was included with my KJW.  -Piano Quote Link to post Share on other sites
PianoBlack Posted January 19, 2010 Report Share Posted January 19, 2010 The front sight assembly base screw (B12) fits the hole in the outer barrel sleeve (B4) so if you swapped out the stock flash hider for something else and still have it laying around, you can use its grub screw to help secure the outer barrel sleeve, though there really is no need as the flash hider does that job fine.

Phenom1 Posted January 19, 2010 Report Share Posted January 19, 2010 I was experimenting yesterday and I was a little disappointed with the results. Â I am considering putting some Pmag shells on my PTW mags, so I tried inserting a Pmag into my PTW. It fit perfectly. So I say to my self, "Why not try the KJWM4 while your at it?". It does NOT fit. Â Has anyone else tried this with the same results? Quote Link to post Share on other sites

If it's too tall, then there's no problems (chop the top when fititng the new internals), but if the mag is too long/wide then it's a bit worse; nothing that can't be solved with some sandpaper or a dremel, mind.

johnyew Posted January 19, 2010 Report Share Posted January 19, 2010 Being the cheap guy that I am , I just couldn't bring myself to buy the PTS MOE grip when I found Element's G27 grip much much cheaper . Â So, installation was simple and straightforward and no wobbes at all with the original screw. Â By johnyew, shot with KM90 at 2010-01-19 Quote Link to post Share on other sites

Â I undertsand about the mag being too tall, so I installed it with the receiver open. Â The markings left behind on the mag indicate that it is very tight by the spine of the mag. Â My concern is that if I start sanding and dremeling will the KJW mags become too loose? Â This is all looking far into the future for the release of T-hum's new mags.

t_hum Posted January 19, 2010 Report Share Posted January 19, 2010 (edited) I have a pmag that fits it my gun. Its had the top cut and the slot for valve components milled out. Â It didnt fit at first. If you look inside the magwell you will see a flash line left from the casting process. It catches parts of the mag. If you look at your KJW mag you will likely see marks from where the stock mag rubs as well. I got out some emery cloth and a small square file and took down the high spots. Â Also note that the valve knocker will not completely recess in its hole and rubs on the back of the mag. It is probably the single largest contributor to really tight fits. Â My stock KJW mag always was really wobbly. The pmag fits like an absolute dream. No wiggle. No wobble. And drops free by gravity power. These cast lower receivers are going to vary from batch to batch so mileage may vary. Â Raven1 fit a RS pmag in his gun no problem with the upper off. I think Dahm had the same results I did.
