Sun Devil billet upper and lower receivers
Samson handguard
Magpul furniture
Brownells 18" barrel
Vortex HS-T 4-16x44
Chip McCormick straight shoe trigger 3.5lbs
JP Enterprises scope mount
*I have not sighted it in yet, just function checked it with 5 rounds. It ejects about 4 feet at 2 o'clock and does not stay open on an empty mag, so I am goin to put the tungsten weight and heavy spring on my JP Silent Spring and see if that will put it at 3 o'clock.

Please post a range report Tacblade, I'm curious how the newer Brownell's barrel shoots.

Nice looking rifle there. I'm actually wondering if the lighter JP SCS spring is the correct fix for this. There is quite a bit of weight and spring strength on the SCS as-is, and I really think it might be set-up for a lightweight/lo-mass carrier.

I will try my low mass JP carrier out of my .223 and see if it makes a difference.

The upper and lowers look slick.

I assembled my Grendel on a Sun Devil Billet receiver set. My only complaint was I paid extra to get a Cerocoated set and when it arrived the color rubbed off on everything. I don't know if they forgot to bake it or had a baking malfunction but I had to get it done correctly here. I thought about sending it back to them after emailing them about it but I am not much for second chances if they can't do it right the first time when they know it is going out the door to a customer. That is why I won't ever own another Kimber pistol even if it was free! But I digress, no other issues with the receiver set and it made a very accurate rifle. Mine is FDE also.

The receiver set and trigger are Burnt Bronze, the rest is Flat Dark Earth. But when it rides in the Polaris Ranger for awhile, it will all be Wyoming Dirt color!!!

I am going off this diagram for my issues.

This is a great looking build. I have been looking at the Sun Devil as well as the Mega upper and lower. How did you decide on the Sun Devil set? How did it look going together?

My .223 is billet MEGA receiver set, so when a guy I know put his Sun Devil set up for sale I decided I would build a 6.5 Grendel. I lapped the upper receiver and it did not need it, it was perfect. I had no problems with anything fitting!

Thanks for the info. Since you have both, which do you prefer? Are they comparable?
I am thinking about a Mega with a side charge handle but the Sun Devil looks really nice as well.
(sorry to hijack your thread, just interested in these two manufacturers)

I guess if I had to chose, I would go with the MEGA again. They have alot of options!

I have tried low mass carrier and a light spring in the JP buffer and a heavy spring and heavy buffer? All setups throw the brass about 1:30-2 o'clock and it never stays open on an empty mag? Adjustable gas block or leave it alone, as it shoots Great!!!
