holy crap. that, sir, is a beautiful machine. i would normally think that the only thing missing would be a pair of perfect breasts but really, where would you put them? aside from that dilemna, it's a beauty. great job, sir.

They would go great in the back ground...but i might get kicked off the forum lol. Thanks for the compliments.

Since this is part two of your build, does this mean they are double GGs? Very nice build. Is a range report in the future?

Just the one Grendel for now. That's the same rifle on my previous thread, i just broke it down and upgraded it. Definitely a range report to follow as soon as i get a day off of work. I'm curious to see how much the matched parts will factor in, the rifle already shot fantastic.

Beautiful!

Beautiful!

Thanks!

[ricsmall]

nice stick!

[biggdawg]

awesome gun!! that looks like one i would love to build and shoot

[COLDSTEEL77]

Thanks yall!

While you're working, I could do the range testing for you. All you really need to do is ship it to me, and the rest will be taken care of...simple. I'll even take pics of everything for you, and you can post them yourself.

That rifle is sexy-sleek. You spared no expense on the components for sure. What loads will you start with?

Haha sure no problem, I know you'll take good care of it...


Honestly hand loading is my next project, I still have to buy all my stuff and do the research. I have some friends that have it down to a science so I'll definitely consult with them for advice once I start. The rifle loves 123 gr A Max, i can cut holes with it...or could before the upgrades. I don't see matched parts hurting it any but you don't ever know until you test it. Thanks for the compliment!

That handguard is rowdy! Let us know how she shoots

Sure will, thanks man!

Very Nice Indeed!!

Looks alot like mine and ThomasA's rifle. Great looking stick

[COLDSTEEL77]

Thanks guys!

[wiuprof]

Great looking rig! I'd be very curious to see what kind of velocities you get from a 28" barrel. It might be close to a 260 Rem. out of a carbine length barrel. Keep us posted.

[Variable]

That is truly one awesome looking build!

If i remember correctly, last time i put it on the chrony while it was on the old upper it shot 2816 with 123 gr Hornady A Max. I'm going to do some testing with the adjustable gas block and see if that has any effect on velocity.

That's a nice setup you have there! Your lower was made about an hour and a half drive north of me.

[LRRPF52]

Now you're just rubbing it in...Since you're at it, can you take a pic of the bottom of the mag well to show how much funnel there it? Those look like great receivers for a heavy barrel build. Oh yeah, tell us more about the bipod.

Thats cool, I like the look of the lower but theres a lot of play in it. The rainier arms upper fits like a glove on my other lowers so i'll probably swap it out for a seekins precision lower

Sure, i'll take some this afternoon.

The Sinclair bipod is the best bipod I've ever used. It's all billet and stainless steel construction with precise movements. It has a very solid pin through locking system that goes all the way through the sling stud and pressure locks with two tri-blade thumb screws. It has spring loaded notched legs with quick release buttons them incase you need to take them off. The thing I like the most about it is the dual adjustment legs which not only go in and out to adjust height but also side to side which enables you to have a wider more stable shooting platform and also lowers the rifles center of gravity also increasing rifle stability.

YOU WIN!!!!!!!!
Very sweet love to squeeze one off or two.........

123gr @ 2800+ is smokin' right along.

Excellent build.

Gorgeous gun. You should frame a picture of that.

Thanks man, i might just do that.

[LRRPF52]

Thanks for taking the magwell pics. That answers my question. Looks like they could have gone with a more flared magwell opening, but that wouldn't be necessary for this stick. There's a lot of meat in the front strap of the magazine well, as well as the rear junction with the trigger guard.

No problem man. I like everything about the lower except that there's a lot of play between the upper and lower even with a accuwedge. Thats a big enough problem for me with this rifle that i will most likely replace it with a seekins precision.

I had the chance to see a couple Seekins rifles two weekends ago, and they were were beatifully executed! A guy I deeply respect, who is a top 20 National Level 3 gun competitor was shooting one, (Not sponsored by Seekins), and he told me that it absolutely was the best 5.56 rifle he has ever shot. He has built his own in the past, and built 3 different guns trying to achieve what he says Seekins achieved with their 3 gun rifle.

I wouldn't hesitate to buy one based on what I saw and what he said.

The problem, at least from what I heard at the match, was that they are a bit "unobtanium" right now.

I agree 100%. I had a seekins sp3 rail on order until I decided to use the adjustable gas block. The rail wouldn't fit over it. I was highly disappointed that I couldn't use it.

I dig those Sinclair bipods. It's what I have on my .308, though I haven't had much time spent with the bipod yet. There is a little slop, but it works well. I like that the legs come off so easily, and can be stored away in a pocket. this is so much handier than their F Class bipod.

[OLd Man]

What did the bipod set you back?
