Home Forums Hunting & Shooting AR and Tactical Rifles My first AR platform in 7.62 Nato/.308 Win

The discussion went like this with my oldest son on speaker phone with wife and I.
Son: "I'd really like to buy a AR10 platform before they ban assault weapons!"
Wife: "Do we have one of those honey?"
Me: "We have a few 308 hunting rifles but not on an AR platform"
Wife: Then WE should get one.
Me: ON IT!

Seekins Precision SR10. I dressed it up with a Magpul bipod, Bushnell Nitro 5-20 x 44 FFP scope, and a sling.
Before I got the scope, I put it on paper with the iron sites then moved it out to 100 yards (last photos). Super accurate with my 308 reloads (41 gr of IMR4064, CCI 250 primer, drop tubed to make room for a 165 Hornady SP)

What is the purpose of this post?

Nice, congrats on your AR-10!

Nice rifle. Looks like it has some potential.

Holy cow ! We are damn near neighbors! Just attempted to fish Canyon Ferry for Walleye before that first big storm blew in. We bailed out Thursday with boat and truck camper just in time. Never dipped a line in the water.

Well, it was interesting and contributed to the forum, unlike most of yours.


Sportsdad, nice rifle. I'd been using a lot of the Hornady and Sierra 165gr SP bullets, but have been even more impressed with the 175gr SMK over Varget and the accuracy loads for both are closer to the same speed than I expected.

Thanks for the feedback!
I'm still looking for what the rifle likes. I'm going to try some Varget next. I do have some 178 gr pulls I may put to the test.

LOL! Yeah, she's a big girl. Weighed in at 9 lbs upon delivery but now weighs in at 13 lbs.

She's a "Vote from the mountain tops" rifle for sure.

SD,

The video was a reference to DLA, not your new rig.

Personally, I like the looks of it and look forward to additional range reports after you've worked with it for awhile.

Yonderings suggestion of SMK's and Varget doesn't sound like a bad one.

LOL antelope. Roger wilco.

That's cool. Wife and I were in your backyard recently too. Just a day trip up through the Swan Valley, and down the east side of Flathead Lake.

How are you liking the shape of that handguard? Does it have a good feel?

Try some 155 scenars man. I still need to try some in my ar10..

So the purpose was to show off a purchase? To get your ego stroked by a bunch of forum commandos?
Do you feel better now about your purchase? That's nice!

You mean kind of like your original post made you feel?

Nothing wrong with a little show and tell every once in a while.

Yeah, no kidding. I thought that's what this forum was for. Personally, I like to see what other guys put together, it gives me a lot of ideas. I think he's jealous.

Sportsdad, nice gun. Thanks for posting.

Thank you gents. Like I said, it's my first. I am primarily a wood stock hunter. This one is for fun, or SHTF.

I enjoyed the op. I appreciate Sd6 taking the time to put together a nice photo spread and show us some groups, and his wonderful attitude that lead to this new source of joy for him. It's nice to see what a Seekings rifle can do, sure it's only one data point, but one more than I had before his post.

There's enough griping an moaning on this forum, why not share our small joys in ways that also help inform others?

If we are too nice to each other down here in the Black Rifle section, please joins up in the top forum. There plenty of politics etc. if complaining is your purpose in life.

They seem unconventional to me as hunting guns, but I've found the AR-10 platform to be pretty user-friendly when it comes to actual use. My .308 weighs about 9lbs scoped and loaded, and my wife and teenage daughter were shooting it to good effect from the bench this weekend, just for fun and practice. Neither are big-time shooters. The combo of the weight, action style, and soft pad make it pleasant.

My wife joins me at the range now that she is retired.

She has 2 - AR15's and she really didnt the recoil was bad at all when she tried the new 308.

I really like my 308, but like my 6.5 better.

I considered a 6.5 "Swedemore" but I have the dies and what not for .308.
I may have to look into the 6.5 some day.

I've thought about dropping a Creedmoor barrel in mine as well, but this is my only 308 left and I still like having both calibers. Not much reason for that other than loonyness though.

I was considering trying the 178gr ELD bullets, but hadn't got around to it. I do have some 168 ELD, which beat the 175 SMK's b.c., but haven't shot many of those yet either except to figure out max charge weight and velocity. Too many rifles, not enough time to shoot...


I made a brake from 17-4 SS for mine since I'm using it for target shooting rather than hunting; it's a little louder but a real soft shooter. The gold color is from heat treat, not a coating; I left it that way just for grins. Topped with a fixed 6x SWFA, it's a good intermediate range gun for cross-canyon shooting with a bit more thump than the -15 platform.

I was talking to an ar shop owner a while back about switching out the barrel on my ar10 308 and he said, "you'd be better served if you keep the 308 as it is, and just buy a 6.5", so thats what i did. There's a lot of utility in the 308 and it makes good sense to have one.

Nice work! I was a machinist for 16 years, wish I had a bridgeport!

Thanks. I've been machining stuff on the side since the mid-90's but finally picked up that mill and matching lathe a few years ago to upgrade from some others. It's a Jet rather than a real Bridgeport but essentially the same thing, right down to the Meehanite cast base. It sure opens a lot of options for gun projects; most of my AR stuff ends up with some machining work sooner or later, and of course the whole world of suppressors is wide open when you can make your own.

Nice Yondering ! I may have to look into one of those. I gotta slow down on my other retirement hobbies first though! I had to retire because my job got in the way of my hobbies!
I sent you a PM regarding another subject.

Very nice. Congrats on your new AR-10!

I bet you voted for Obama and Hillary. Ignore is where you belong.

Be glad you live in the good old USA. A lot of other places, You'da been stoned to death for being so phugking stupid.

What kind of a place would this be, if we couldn't share our new toys?

Were you late to the circle jerk formed for this noob to brag about his purchase?

Probably less lame.

Congratulations. You're in the .00003% of Fire members that don't like looking at other people's new guns.

To put it in perspective, you're like a Beto voter.

Hell, it interests me to see other's builds. Especially the AR10 platform because we really don't see much of them here. I think it's really cool when someone posts up good targets in the black rifle challenge with them too. I've only managed to shoot around 1.5 moa with my AR10 308, but the 6.5 cm went sub moa right out of the gate and with no load development (per se), just used my other ammo I had laying around for my bolt guns... As it is, 3 of the top shooters in that challenge are using AR10 platforms. I just posted up the results of that challenge there a bit ago... Guys, get out and shoot... If you are having to use "$33.00/box of ammo", learn to load your own...

The point of posting build pics/descriptions is to inform the readers of the possibilities for our own builds.

The point of liberal trolls is to stir up crap that they are jealous about, then to project their own inadequacies and mental instabilities upon others.

To be honest, I shrugged his comment aside like a typical troll that I've dealt with since the interwebs formed. Aka Al Gore Invented The Internet Days.

That was a "bought", not a "build" dumbshlt.

Nice rifle, Sportsdad. I love shooting mine, hunting too, but the weight can make for a long day after a while.
