And it is very well made. Considering they made the Syrac kit there are a lot of similarities as you will see. There are some key changes which I thought I would share. Unfortunately I didn't take pics of the Syrac kit to compare (I sold it to get this one). I ordered the Carbine kit for my SBR build.

Nice boxing in foam, not just flopping around in a tube.



Here are all the parts which we all know what they are. They do include the bushing for the upper and installation tool if you choose to use it. After talking to the owner he said most people use the bushing when firing FA. Even then it's not needed but it's extra insurance.



Here is the gas block with the bleed off port on the side of the adjustment screw (vents to the front). Once again the machining on this was outstanding. The plug and adjustment screw were very smooth (except the detent, but that's a given). The detent system is way better on the adjustment screw than the Syrac kit.



Here is the adjustment screw. This is where I wish I took pics of the Syrac version to compare. The part all the way on the left is where the main interaction with the gas happens. As you can see it is smooth and would build up minimal carbon. Also, the detent is not milled grooves which could easily build up carbon (on the right). It is now just flat spots (it's a square basically). It works. I have to purposely try to get it to the next adjustment setting. So I assume there is 4 adjustments per rotation.



And lastly the bolt carrier. I finger fucked this thing all over the place and let me tell you it is smooth. I consider this a very crucial part and there was not one rough edge or burr anywhere. It slid into my upper super smooth.




I was going to install it this weekend but I had to work. I just wanted to post my pics because a few of us have been talking about it. This kit is completely serviceable without taking your handguards off or anything else. Hopefully before the month finishes I will build it and give you guys a range report. I am still waiting on my stamp but my buddy has a registered lower which we will test it with.

Oh, and I heard Rainier will be carrying this kit soon.

UPDATE:

So my stamp was approved last week and I finally shot it today. The system ran flawless. The first round ejected hard at 1 o'clock. After 2 or 3 rounds of tuning the brass was ejecting perfect at 3 o'clock. The bolt always locked back on an empty mag. I only ran about 200 rounds but it was perfect. Needless to say I am very happy with it!! My Comp M4s should be here tomorrow.
ETA: To those concerned with the bleed-off making the hand guard dirty, it is no worse than my AA kit. I think it actually runs a little cleaner in that aspect since it directs the gas forward. I had just a tiny bit of carbon just under the front sight on the right side, and it wiped right off. Also, my KMR never got too hot to hold, just a little warm.

I would say no to the AA carrier. But I hear there is a low mass carrier in the works. Email them with your requests/questions. The owner will get back to you or you can call him and he will explain things in full detail. Like I said I am using this kit in my SBR build and I have been bothering the shit out of him, but he always answers the phone, or calls me right back, or responds to my emails. Give him a call on Monday or email him now.

I don't foresee any issues with the adjustment at all. IMO it is an improvement. If you are worried about it you can take out the adjustment screw and clean the piss out of it after each range trip anyway. And why would you want a non adjustable model out of curiosity?

Well then you could set this kit to the max setting and never have to worry about it again. Kinda the same thing. Just change springs and buffers as you see fit.

Better to have and not need, than to need and not have.

Could you do me a favor and take pics of the gas block from the front with the rail on? Pics of the top, bottom, and sides would be appreciated. Thanks!!

Hand guard on for all pics. Take all of them from the front. I just want to see the clearance from all angles.

Thanks!! There's more room than I thought under there.

How did you get the gas block perfectly straight so it didn't touch? Just by eyeing it like the instructions say or did you have to put the hand guard on and test fit it a few times?

So when can we expect a range report?

Nice. Did you see I got mine installed?

Yea I started another thread. Here.

I really couldn't tell you. But if I had to guess it would be less using the piston kit since there is no gas tube going back into the action.

Good to hear! And quit posting so much.

Clamp on specs.



Solid specs.
