Originally Posted By tnbigdawg: 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. Form1 on top, Form4 DDMK18 on bottom: https://i.imgur.com/hYzcxYZ.jpg https://i.imgur.com/Y15bwSy.jpg View Quote 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 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). https://i.imgur.com/NjNuPt5.jpg https://i.imgur.com/Tf33Get.jpg 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. https://i.imgur.com/zjP1Ov8.jpg View Quote 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. Attached File |

CD View Quote 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? |
