Group Buys Aftermarket AI "Obsession" Chassis - Group Buy

I received my chassis today. Looks awesome I’ll have this thing together later tonight can’t wait to get it to the range.

edit.
From start to finish it only took me 45 mins to do the conversion. Sam made the instructions super simple.

FedEx had mine arriving Friday. Now they say Tuesday. Either way I can’t go get it in and installed
Bummer...I hope it comes on Friday and isn't delayed. Unfortunately with the Holiday weekend some of them are getting pushed to Tuesday. I know the Ground option was 4 days to the west coast :(

Not the end of the world. Friday would be awesome. But I work all weekend. And wife is off Monday so she will want my full attention so it will be Tuesday before I can do anything but drool all over it anyways. I’m just excited either way. As I’m sure you remember when I first messaged you. I bought the AI for your chassis lol. And I couldn’t be Any happier that I did

damn, that black looks fuckin ( o )( o ). makes me question getting the FDE. Glad you got it together. Youre going to fall in love with your AI all over again.
 
I don’t know what’s up with FedEx, but I hope the shipping times go back down for you West Coast guys. The longest time was 4 days via ground, so sending them out on Tuesday (which don’t get picked up til 6pm) should have been Wed-Thur-Fri-Tue for the delivery. I’m at a loss as to why that would be pushed out to Thur or Fri of next week.

Then at the same time, guys in NC are getting theirs today.

Damn, these look good.

I have quick question regarding the brass washer. I notice they have a slight conical shape, they are not completely flat. Does the orientation matter for assembly? I didn't pay attention to this when disassembling and I don't see a difference in the mating surfaces.

The washers should be flat. My suspicion is that when they were removed/pried out of the epoxy during de-bonding that they got bent. As long as the old epoxy is cleaned off prior to re-assembly, I think you’d be good either way. The torque on the action screws during assembly should be more than enough to flatten the brass washers back out. If you really want new ones I believe someone said Mile High has them in stock.
 
These are brand new from Mile High and it does look like they are stamped, which causes it. The ones I removed also looked slightly conical too with slightly more epoxy on one side. I know they are brass and should flatten pretty easily, but I wondered if the torque of the action screws would be enough.
Sounds like it's not an issue, I will just keep them facing consistently when I assemble it.

On another note, has anyone considered using a tapered applicator syringe to apply the epoxy. That way you can get a nice consistent bead everywhere you need it. Or is the epoxy to thick to be pushed through even a larger opening of the syringe?

If they are punched and have a sharp edge of "flash" on them, you could always lightly sand them on a flat surface with some sandpaper.

The first couple times I re-bonded the action back to the chassis, I used the Devcon plastic-steel epoxy (the kind that comes with the AX buttstock kit). One time I mixed them first, then put them in an epoxy syringe. Another time I bought the syringe nozzle that mixes the two parts together as it comes out. It's definitely way more of a pain than using the putty with the brush. Not only are the syringes extremely hard to push out the epoxy, but they become messy when the epoxy comes out when and where you don't want it to.

From what I've heard the factory AI techs use the aluminum putty and a brush, which is what I have come to prefer using as well. My recommendation is to do it that way as well. The kit has everything you should need, other than some rags and alcohol or degreaser. The application doesn't need to be perfect, so as long as you have enough epoxy to fill the 0.031" gap, it'll be all good. And if you completely botch it you can clean it all back up and I can send you a new epoxy kit.

If you go the syringe route, I would recommend "West System Epoxy"" syringes found online at West Marine or most any Marine Store, the tips are easily cut to provide the perfect application bore size and angle.

Those are the exact ones I tried with the lower viscosity plastic-steel epoxy, and still didn't care for them in this application. I think the aluminum putty is even thicker and will be more difficult to apply with the syringe, until you open the tip up so large that more comes out than you want.

In any case, try what you think will work best! Chances are it'll be fine. As long as you don't go overboard in the Quick-Loc barrel retention area (make sure to tape off the ID of the barrel tenon threads on the action!!!) you'll be good no matter how you apply the epoxy.

I would agree, looking at your video, that is thick stuff.

Couldn’t get stuff sold fast enough to jump on the bandwagon... maybe I’ll get lucky 🍀 and Mr. Sam will do another run... HURRY UP!
Still unsure if I will or not, but I’m making a list of interested people. If you haven’t already, shoot me a PM with your name and contact info and I’ll mark you down.

Almost back together. I would highly recommend fully watching sams videos then doing it. I didn’t do that. Lol. And not working with the video.

Also do the butt stock first.

I did get it all together in time. But I think the Florida heat just helped the epoxy cure faster so it was close on the butt stock.

Sadly I can’t get it all back before bed. Hopefully tomorrow after work I’ll have it fully back together and get some good pics.

btw Sam did a awesome job labeling everything. You definitely went above and beyond.

Looks great man! And thankfully it looks like I did the math right on the 16.5” barrel haha

I apologize for just throwing out the full install videos. I was intending to edit them so it’d be easier to follow along with, but that stuff isn’t my thing and I decided to be lazy and leave the uncut versions instead. Definitely better to watch the video first; following along with it will be very slow.

I still wouldn’t recommend doing the buttstock first, since that will really throw the balance off to the rear and make it more difficult to assemble the chassis to the action.

yeah. I horrible at following directions. More of a Just do it type person. So I actually slowed down in parts following the last video. So by the time I was ready for the butt stock it really was pretty hard. But it worked. And it wouldn’t of been the end of the world if I had to buy the other stuff just for it.

And yeah. The barrel length works out perfectly. Or well so far. Lol. I’m sure I’ll develop a method to make it easier to take on and off.

Well I got it together. And I couldn’t be happier with the results. That being said. I want everyone to know that hasn’t installed there’s yet. Reinstalling the magazine catch is the hardest part of the entire thing. And @samb300 really made it easier with the assistance of the instal pin he put in with the other parts.

now I just can’t wait to get to the range and hopefully a match soon.

Looks great man, thanks again for the support throughout the entire design and manufacturing process.

The mag catch is a pain in the butt for sure, the installation dowel hopefully helps. It’s one of those things that you either get on the first try, or it takes ten times and you’re swearing the whole time haha

yeah I again didnt fully look at everything. And I struggled and struggled until I finally looked and found the installation dowel. And then it took like 5 seconds. lol.. Of course I was in a time crunch to install it all. So that made it take even longer lol..

and your welcome for the support. But Thank you 1000000 times more than that for designing this chassis and making it happen.

So were the pics taken in a shoot house? Or do you just live in a REALLY bad neighborhood haha

Its the last remaining building on a old Air Force Fuel Depot. The city I work for now owns the property, however kids are always trespassing and doing graffiti on the building. Actually the area is a low crime rate higher class community. However you know how teenagers can be.
 
My kit will be here in three days and will post pictures soon after. FedEx also changed my arrival date possibly because of the Labor Day weekend. Can't wait to get this thing together. Thanks Sam!
Labor Day has messed things up, but the shipping times to the West Coast have sucked! There are a couple going to WA state that claimed 4 days ground, and are now being estimated as 7 business days.
 
Fedex Ground - when it absolutely, positively has to be there whenever we feel like it.
Certainly seems that way. I’ve had good luck with them in the past, that’s why I’m surprised by the flip-flopping delivery dates. The other thing that sucks is that when I dropped them off at 8:05am on Tuesday, they didn’t actually get picked up until 5pm.
 
I have my balance point about 3” in front of the magazine well, which is about perfect for using Game Changer type bags. That’s with the prototype chassis with the 1.5# internal weight and one MDT external weight up front. I think with the production chassis and 2# internal weight it’ll be just about perfect.
