Franken AR 6940

[DesertFox]

Here's a custom lower that alone cost me more than a M&P Sport. CMC flat 3.5# trigger, KNS anti-walk trigger pins, oversize mag release, Mako butt stock, Pacmeyer Vindicator pistol grip, Magpul aluminum enhanced trigger guard, Noveske QD receiver end plate, Mako magwell grip...

I looked at the M&P15T and the Colt 6940, decided I wanted one or the other, then ended up building my own.

Now I can get on to figuring out which Night Guard is going to follow me home next.

Sweeeeet! I like the trigger, never seen one of those. Thanks.

If you free-floated the barrel on a Sport, prolly nothing and I think M&P15 Sport are super, by the way. I had most of the parts for the lower accumulated over time. So it was more like $5 here $20 there - not all at once. Plus I was searching high and low for specific parts that I wanted - flat trigger for instance.

The upper is a Colt 6940. Like the monolithic rail, QD attachments and flip-up sights and it ends up being lighter than the 6920. So far, I'm thinking it is the most accurate M4 upper I've shot. Typical Colt 1/7 twist. Need to pump some more off before I get a good idea of group size.

Now I'm drooling over the Colt CRP-18... Grrrrr... Better grab the 310NG first... Hope my wallet doesn't put out a hit on me...

I've desided to go with that "general route" and build my own from the ground up after finding too many likes and dislikes on all the AR's. I also want something that's good to 300 yards (at least).

Also want and like the SR556 and will have one down the road (Mini 14 needs a cousin).

IF I can find a good deal on an AR 15T that will also be in the collection.

You will not regret building your own. Beware that certain grip/stock choices can make other parts unnecessary. For instance, the Magpul MIAD grip means you do not need a trigger guard, which is a $8 or $15 additional part otherwise. Get the receiver end plate you want, not just the standard one. I like QD points so I went with the Noveske QD endplate.

Better trigger is the other great reason to roll your own. Better triggers can be had for $45-$250.

300 yards is completely reasonable.

There are parts of the SR556 I love and parts not so much. No Mini-14 on hand here so I'd be more inclined to go with a 6940P upper if piston was on my chart.

The M&P15T was on the shelf at $1,399 or something at the LGS while the 6940 was $1,500. I'd go Colt for that kind of money and a monolithic upper. But for $750 budget, the M&P15 Sport is just what the Dr. ordered.

The last build I did that was just a basic stripped lower, LPK, CAR stock kit, optics ready M4 style upper, FFL transfer and shipping came to under $625 with no sights or scope included. The build pictured above was over $1,500. Lots of room there, depending on parts used, for a wide range of budgets.

Just so you know a $600 sport and a $150 scope and rings will shoot 300 accurately and easily. As the barrel heats up it loses some accuracy but when you free float it that problem goes away. When you are prairie dog hunting you arent shooting fast enough for the barrel heat to be a problem. I was shooting them with a stock Sport with an 8-32x42 scope at over 250 before I free floated mine. And I do agree with smart parts shopping you can build a heck of a rifle but if you start with a Sport you have solid quality parts and an extremely accurate barrel to start, plus enough money left over for quality additions and ammo. I built this and bought a 1000 rounds of Federal ammo for well under $1500, way under.

Nice shoot'n irons gentlemen.
I'm looking into Mag Grips...any suggestions anyone

 

[oneyeopn]

I like the mako magwell grip, the only issue is if you have a plum crazy/new frontier lower it doesnt fit as well around the sharper corners.

I (obviously) like them too. I've screwed up a couple grinding on them to fit some non mil-spec applications - like enhanced trigger guards, 15-22, etc.. I actually tend to not grip the magwell there but rather like it as a magwell funnel.

Recently started using an AFG2 and am liking it more. So if I was going to go with one or the other, the AFG2 would win out for the money, for a grip.

I dont shoot that particular rifle offhand, I dont know many people that can shoot sub-moa offhand. I have a rifle that I shoot offhand that I built for less than $600 as she is right now:

This is the rifle I shoot offhand, I am entirely pleased with how she shoots to a little over 100yards.

So. Fill me in on the likes and dislikes of the SR556.

That's about what I'm looking at for a S&W AR. Is there a difference in the barrels between the 15 Sport and 15 T ? Heard rumors the "T" had a better barrel ??? Definatly going/doing freefloat reguardless. Is that the "yardage adjustable" scope ? I also want Iron sights (back-up if scope takes a dump). How do you go about that with the free float barrel ??? Thinking it would loose some accuracy with heat if mounted on the barrel (???). ...nice Deere,needs a wax job. (I have a 445).

I'm already hot on that trail. "Driving myself nuts" Imput overload ha ha. All I know is,I'll end up with three different AR's in the end.

Ruger SR556

So. Fill me in on the likes and dislikes of the SR556.

Carrier tilt? Unknown as to if it is a problem with the Ruger piston implementation. I do not have a piston AR as of yet. I'm about to pull the trigger on a Sig 716, which would be my first piston AR.

Jury is out as to if a piston is even needed. They do run cleaner and cooler. But as of now, I'm not doing any full-auto or surpressed stuff.

They seem heavy? I think they are 7.5# or so - not unreal heavy but seems a bit front heavy.

I do like adjustable regulator. But I like the Colt CRP-18 adjustable gas block better. So for the money, I'd get the CRP-18.

The bolt looks really cool with Ruger etched into it. Flash hider looks cheezy to me. It isn't a monolithic upper. I don't think it has any QD sling swivel holes.

This 6940 upper is exactly what I was looking for. My wife's setup is a 6720 upper for max weight savings. The 5.45x39 upper has even less recoil than the 5.56, which is also very easy for her to shoot.

The M&P15T seems nice but at $1,300+, I start looking elsewhere. Even if the barrel is better than on a Sport.

thats a 76 Deere, needs more than wax LOL. I dont know what barrel the "T" has. If it has the 1:8 5R barrel then that is what is on the sport. If it doesnt and has the 1:9 chrome lined barrel I dont believe it has a better barrel. When you buy a sport there are a few things you do not get, i.e. a dustcover and a forward assist but you do get a barrel that will blow your mind as far as accuracy. Before you get it broken in you will be amazed at the accuracy, I was and thats when I decided to go the big scope route, You can get a free float quadrail that will enable you to put BUIS on it. you may not be able to shoot a fly off of the gatepost but it will be more than accurate enough.
Yes the scope has an Adjustable Objective (AO) that adjusts by yardage and I really like it. It is a Bushnell and I have the same scope on my 308. the only difference I see with the free floating barrel is after a bunch of shots shooting real long distance other than that there is no appreciable difference.

Don't like the twist (1:9 too fast ? or ???) or is it the chrome ?

Doing my homework and trying too keep up with you younger shooters. This "old dog" still likes new tricks. ;o)

 

[storeyteller]

Same barrel.

Product: Model M&P15T - 5.56 mm, Tactical

1:8 is faster than 1:9.

My bad. I had it backwards on the twist.

Barrels are the same (in that info). Thanks. I seem to run into conflicting info at some of the Dealers. Could be old style or new style. Gonna have to start writing down model numbers,check double checking before I'd order anything.

 

[storeyteller]

Happens to me all the time. I'm backwards most days myself, and its kinda counter-intuative anyway.
