Definitely practice on another lower. I screwed one up at the very last step on the 5D Tactical jig, milling out the trigger hole. Not sure if they changed anything, but at the time the setup had a fairly big endmill for the trigger hole and upon startup of the router it snagged on the aluminum and caused the router to jerk out of jig. I used a Dremel and file to clean up the hole, but I now have a lower with a very big gaping trigger hole.

I ended up ordering another 80% lower with my engravings and different serial number and the milling turned out okay on that one so it's Form 1'd. The other just sits in a box and my OCD is making me want to demill it.  What sucks is, I had both lowers Type III anodized anyways after completing them because the shop I sent them to offered the services fairly cheap.

Big oof...I hear ya.  I’ve done four 80% lowers now.  Each one of them had their quirks during the milling process but the first two were just buggered, dimensionally speaking.  The last one I did, about a month ago, is the best one both in fit and internal finish.  For me I think it just came down to how securely I fixed the lower in the jig fixture.  That and just going nice and slow and milling 1/3 to 1/2 the recommended milling dept hash marks.  I wish I had a drill press for the pin and safety selector holes, but I don’t want to buy one just to drill 6 holes in less than a dozen lower receivers.

Yours looks great though.  Very nice.  Oh yeah, would you mind telling me where you had yours anodized?  I was thinking about US Anodizing, but I’ve heard they’re not taking new work and have had issues with faux Colt markings in the past.  They also appear to be really expensive.

I forgot to mention my first one (that I might demill) was dimensionally FUBAR'd too. 1) It was off center so the walls aren't the same thickness. 2) The jig didn't allow the removal of enough material in front and the hammer would strike the receiver even when fully assembled with an upper, bcg, and bolt catch. I had to devise a way to allow the router to cut more forward by 1mm. I had a thread on it but can't find it anymore; my search abilities are handicapped, but it was titled something like "Problem with 5D Tactical Jig."

As for the anodizing, I just checked the shop's website and they no longer offer the service but they refer us to Vegas Metal Finishing (FFL).





Do they make the Insight dual pad with longer cables? I prefer the ATPIAL-C towards the rear so I can c-clamp grip the handguard just forward of it. The cables barely reach by having it this way.

I don't believe they do. What I ended up doing was removing the irons and moving the PEQ all the way forward on the rail. Then you can grip it a lot better and your hand won't be in the way of the illuminator or laser. Even without your hand there I would imaging you're going to get a lot of splash back from the IR hitting your rail and front sight.

Well, I know it’s not technically clone correct, but I went and got a colt factory 10.3”. I want to have a new barrel to install when my RC gets out of jail. That way it’s a clean slate, new barrel, bcg, upper, 4prong and suppressor.

Anyhow, here is the new m4cqb along with a new demco mueller brass upper receiver. I will probably install the m4cqb on my diemaco upper, which will leave me with the mueller upper, and a new, never shot ballistic advantage barrel. At some point ballistic advantage released a CHF, chrome lined crane spec barrel similar to the CHF dd barrels out there. I do wonder if these new colt m4cqb barrels will ever be used in the field. Seems more efficient than chopping a 14.5” every time for a colt. I know FN and DD provide factory 10.3”, it only makes sense that colt would follow suit.

My wrench was the same way. If you line the wrench up and sort of work it in from side to side, it will settle into the notches. With my wrench, same as yours, one side was slightly rounded whereas the other side has a sharp edge from being stamped out, so it seems. Use the "rounded" towards the receiver when start to rock it into the grooves.

How did the classified defense do? I'm thinking about ordering one. Have you ever seen a dd barrel nut, where you can see through a little gap in the notches from the outside to the inside? I've had two, and both ended up with little gaps where I could see into the barrel nut. I just so happen to have a pic. Barrel nut was torqued to around 35 ft/lbs. Are you supposed to get a new barrel nut every time you reinstall the barrel nut?Attachment Attached File

Thank you. I haven't had any issues yet with my cheapo ris ii wrench, but it always feels like it could slip at any time. I don't change enough barrels to really justify needing the beefiest one, but it'd be nice to have for whenever I do a barrel change.

I don't remember seeing the gaps in the barrel nut when I installed it brand new, but when I took it off recently for a barrel swap I could see the gap in all 4 recesses. The first ris ii I installed was used, and the barrel nut had the same gaps. The nuts aren't damaged or deformed in any other way. The gaps all run with the threads. To me it looks like it could be caused by over torquing, but unless my torque wrench is waaay of calibration, i don't see how that could be. It works just fine and torqued to spec without any issues, so I suppose it's safe to proceed as is? Would you feel comfortable shooting it?

that's a relief. When I didn't take notice on the new nut until my re-install, I became worried it was from being over torqued. Thanks for the info. It appears the threads are what causes the “crack”. Where the threads stop, it’s fine, but the “crack” appears where right where the threads start. Strange that it’s fairly common, but at least it doesn’t seem to cause any issue.

It honestly helps with it being that tight. It feels more solid when tightening. Just don't stray from a perfect arc when tightening. That is when the wrench tends to slip and cause issue. Glad you could follow me, I wasn't sure if it made any sense.

I recently did a Nodak and I found the best way to get the detent hole right was to cut off an a2 grip just past the mounting area. Bolt it to a finished lower and use tape on the bits to mark the depth needed. If you use enough tape, it will work as a stop as well. Then bolt it to your 80% and let it rip.

Nice. That block one does have character. I like the m4-2000. For the price, you can't go wrong. I've been wanting to get on or possibly the 556sd.(is that what it's called?) So you're going to retire the block1, and bring out the block2?

Yeah I love the m4-2000, if I could do it all over again I probably would of bought a NT4, just for clone reasons (even though m4-2000 is marked with a NSN and cage code), but at the time I wasn't thinking about clones.  Yeah, switching out an outdated system for a new outdated system, haha! But that's the name of the game in the clone world, right? Honestly though, I really just feel at home with these systems, it's a system that's tried and true.

I just got one from a friend for free. It’s awesome. Does what it needs to. I recommend it for price and purpose.

Agreed. Not much more can be done to improve upon this weapon system. I wouldn't say it's completely outdated, but it could be lighter and more current with a different handguard. (I'm a sucker for quad rails, so for me it's as good as it gets!)

Thanks for the info. I see a lot of Kac qd mounts being used in the thread, and very few of the other. Wasn't sure if it was because the other system has issues, or if it's just because...Kac? I was thinking converting a couple slings over to the qd push button, and wanted to give that one a try
