We arr still working hard on the new shop but hoping to be 90% operational early next week.
In the mean time Ill dig through the photo gallery and see what I find. This one is called things that happen when the guys are tired at the end of the day but still want to screw around with stuff around the shop.

Lots of work still to be done but everything is now here and the old place is empty. I still dont think its hit me yet that this is the new place because its happened so fast but it really is a huge upgrade! Setting machines in place tonight and I'll get them trued up over the next day or two. Still need to build benches and get all the small machines running too. Test box and cerakote booth are in place so once we get the exhaust ducting done they will be operational pretty quick.
This new place has almost as much warehouse space as the total footprint of the last place, plus another 2k feet of offices and a storage area with a secondary lockup for ALL of the work order bins which I'm sure our customers will appreciate. It will also allow me to do more videos in the shop without worrying about exposing customer info.
More area to stretch out. More secure. More capabilities available to us in house than ever.
Thanks to everyone who has helped us make this possible and to everyone who has helped us with the move! Thank you to our customers who have been so patient over the last week. You all really are the best!

We are closed to walk-ins for the time being. We are moving to our new location and will open the doors again soon but it may be a while before we do. Theres a lot of work to do before the front is ready to go. You can still send in work to the old address for now just like normal. The shop should be fully operational with mail in stuff again next week.

That gap shouldn't be there. Someone has broken the barrel extension loose on this Mr. 556. Whether its a factory defect or from shoddy craftsmanship is hard to say, but that pin and weld sure wasnt factory. Unfortunately if your barrel extension comes loose the barrel is dead. While I don't know what HKs spec for a barrel extension is, standard AR extensions are 150 lbs so I doubt theirs is too far off from it.
The first sign of trouble was the gas block that was canted slightly. There were no obvious reasons why beyond a misalignment between the index pin and the notch in the barrel for the gas block, which honestly wasn't a very German thing to do.

What a wild ride the last few weeks have been and it's just getting started!
If you haven't heard already, we are taking over production of the Allen Engineering AEM5. This has been in motion for a while but we finally have a bunch of the components here and ready for assembly. I also started page so if you are into clones or AE cans in general, make sure to follow for updates. We have already been fitting collars and that sort of work for a long time now so it's awesome to be able to bring this legendary suppressor under our roof with Ron Allen's guidance.
On top of that, we have already outgrown our shop in less than 2 years! We have reorganized the shop several times to make things work but we are standing on top of each other quite often. An incredible opportunity came up that I couldnt pass up so we will be moving soon (hence the redacted location, for now). It will also enable us to offer more in house services we couldn't before like cerakote along with purchase some machines we have wanted for a while. While I don't anticipate much down time for the move in regards to upper builds and machine work, we won't be able to take serialized stuff for about 30 days once we submit the address change to ATF. I will post more details about this soon but if you are thinking if sending work in, get it here ASAP.
Speaking of machine work, we are picking up another gunsmith lathe today so we should be able to significantly increase the throughput of barrel work at the new place.
I'm incredibly thankful for all of you who have supported us over the last couple years! I'm also super proud of our team who have worked so hard to build this. This company is much more than just me. Trajectory Arms is a dedicated team of people joined by a mission to always put our best foot forward regardless of what we do.
I'm humbled and excited by everything ahead of us. Thank you for coming along with us!

You don't understand, I wasn't asking.
This is that barrel nut I posted in the stories a little while back that broke the armorer wrenches. The index pin and receiver were damaged from too much torque applied to the BN during installation in an attempt to get the holes to align for the gas tube. The barrel nut was the type that needed to be aligned with the upper receiver for the tube to slip through. The excessive torque in combination with whatever schmoo was used on the threads locked it up tight. I was given permission to scrap the BN in an attempt to save the barrel and receiver if possible. After removing the out ring by cutting relief cuts in it and prying it off, even the pipe wrench wouldn't break the nut free. So it went in the lathe and I relieved the barrel nut. Eventually after relieving enough material, the tool snagged the nut and twisted it off.
This one gets a prize for most difficult barrel nut we have had to remove.
The good news is with a bit of fitting and trickery, we can probably make the receiver and barrel serviceable again.
The gunsmith that did this likely didn't have much experience with ARs. Gunsmith =/= AR armorer and vice versa. Be careful who you send your work to.
Remember that I post these things not to shame anyone but to reinforce why we do things a certain way so we can all learn from it.

Many won't know the extent has helped our company grow, directly and indirectly. From taking time to give business advice to letting us jump in as a vendor on machine gun days so we could demo guns, along with all the work he and the guys at have sent us over the years, my heart is truly full of gratitude. Rest easy Neal. You will be sorely missed by many.
