Are there any .5 MOA semi-auto rifles currently available?

My Colt HBAR upper 1:9 with a CMMG lower, A2 sights is a .5 MOA gun. All for the low, low cost of $500.
 
Well, I was going to say that .5" with a semi-auto rifle is asking a lot but it seems that everyone and his brother has one that can do it. What do I know?

Don't despair, it is asking a helluva lot to get a semi auto to consistently shoot 1/2 moa groups. Not the odd "accident" here and there, but consistently. It can be done, and LBC makes a damn fine rifle, but don't let people fool you into thinking everyone is doing it and it is the new standard. This is the internet, people stretch the truth more often than not.
 
The FNAR with the heavy barrel is probably the one rifle that is fairly available these days and is said to be sub MOA. They go for around $1400 give or take $100. The M1A can definitely do it but you will either need to buy an NM model or get a Loaded model and do the accuracy upgrades to it (unitize the gas system and bed the action). An AR with a match weight barrel and a match trigger should be able to do it also. Of course any will require the proper weight match ammo or handloads.

stretch?
if one is able to hold 0.5MOA with any kind of rifle, he should give the olympic committee i call, they might have a job for him in the national shooting team.
heck, if you are able to consistantly hold 1MOA, still give them a call.
0.5MOA goes quiet a bit beyond 'stretching'.
 
Well tuning a semi auto and handloads to shoot sub MOA is one thing. To actually shoot sub MOA is an entirely different thing all together. And yes there is a lot of BSing about shooting at range and I am assuming no one is really calling anyone out because either they do it also or don't want to be embarrassed if they are really the only bad shooters out there.

Oh and also there is a big difference in shooting well at 25 yards then at 300 yards no matter what they tell you at appleseed.
 
Benchrest shooters regularly shoot groups much smaller than .5 MOA, but last I checked the Olympics weren't interested in benchrest shooting.

True, and to make matters worse, the OP was talking .5 moa, not moa.
 
A good point is being brought up here. Yes my les baer will shoot under .5moa. NO not everyone who shoots it can do it. I can under great conditions with a very good bench. In the real world shooting prone with a bi-pod if I shoot 1.5 moa its a good day. I once shot a 2.5" 5 shot group at 400 yds prone off the bi-pod but the same day I shot a bunch of 5 to 6'' groups so I could say "hell yes I can shoot .5 moa at 400 yds" ONCE out of maybe 5 or 6 groups if the wind isn't blowing. I would say most rifles are capable of way more accuracy than the guy behind them.
 
Guys,

You need to remember... 1 or even 1/5 MOA at 100 yards is a LOT different than at longer ranges.

I honestly don't see what the big deal is. I've had PLENTY of deer rifles that held 1 MOA or less over the last 30 years. I never considered that all that exciting.

Now... lets say this... am I talking about 5 or 10 shot groups with a sporter barrel hunting rifle? No-- because you NEVER FIRE a sporter barrel hunting rifle 5 or 10 shots on a hunt.

I expect different things from competition-grade rifles than I do hunting rifles. However, you CANNOT discount a rifle that you can EXPECT to fire a sub-MOA group at 100 yards any time you set up and do your part-- regardless of shooting 3 shots, 5 shots, or 10 shots.

I think this thread needs a heavy dosage of reality check

(1) 3-shot groups are used for a reason. Unless you let your bore cool down significantly, anything more than a 3-shot group with a large rifle is going to start opening up, regardless of rifle. With semi-automatics, there's a tendency to fire multiple shots back to back. If you want your rifle to do its part, you need to do your part.

(2) I said some can do it, not all. Occasionally you'll get a bone stock PSL that'll shoot incredibly well. And I've also seen some people perform modifications to their rifles (partial free float modifications by reaming out some of the wood and more) to get them to shoot even better. The newer ones seem to be better, as the Cugir plant further modernizes with new equipment.

Fact is, some platforms can do it. Most can't. But there's such a thing as accurate enough for most people. Unless you're doing competition shooting, 1 MOA is enough for most people. Find a gun you like within your price range, and go for it.
 
I didn't mean for the focus of the thread to be .5 MOA. Les Baer advertises their 6.5mm Grendel Super Varmint as being capable of .5 MOA, so I was looking for other options with similar accuracy.

My question should be: What is the best semi-auto rifle (larger than a .223) in terms of cost/accuracy, that is not on back order for 6+ months, and has readily available magazines and ammo. The intended use is shooting 250+ yards with a scope.

I really like the Les Baer 6.5mm Grendel Super Varmint, however I'm concerned about ammo availability (I don't intend to reload).

DPMS and Armalite are backordered for 1+ years. The LWRS and POF gas-piston 308 ARs are expensive, and I heard they aren't as accurate as direct impingement 308 ARs.

I also thought about the LaRue OSR and the Fulton Armory Titan, however I know nothing about their backorder time or accuracy.


What would you buy?
 
I suspect that you'd get a Larue before you got a special-ordered LR-308, and you will pay a similar price on Gunbroker for the DPMS or the Armalite.

If I did it again, I'd just get the Larue OSR. You can't build that rifle cheaper than Larue sells it.

Yeah because it's an easy crutch to use when you're basically trying to LUCK into one group to take a photo of and proudly proclaim that your rifle shoots X MOA "all day long"

If your patient enough 3 5 or 20 rd groups, bolt semi, or lever won't cause this "opening up"

Truth in accuracy reporting

ONE

Don't make any kind of claim of accuracy on a 3 shot group, You're only 3/5th of the way to a useful indication of potential accuracy with a 3 shot group. Just about any rifle will luck itself into great looking 3 shot groups from time to time. Even the junkiest rifle stands chance of "missing" in the same direction thrice however this likelihood is greatly reduced with a five shot group. which leads me to no2

TWO

Accuracy of your firearm cannot be claimed from ONE lucky group. You must take the good groups and average em in with the bad. In my opinion four 5 shot strings is the MINIMUM to even begin to make any serious claims.

THREE

Understand that every rifle is it's own individual, just because the rem700 you bought shoots 3/4" groups is no garentee that the rifle that was sitting behind it on the rack will do the same.

FOUR

Don't ever use the cliché "All day long" when making an accuracy claim, as soon as most read those words most assume guideline No2 applies

FIVE

I don't care if you use millimeters or inches, decimals or fractions for the love of god drop the measurements based on US currency. International members may not know how large a dime is and even if so depending on caliber a rifle that would shoot into a dime"all day long" would be benchrest grade. When you apply this claim to a 10/22 or an marlin336 people instantly don't believe you

SIX

Learn how to measure groups properly, groups size is determined by the extreme spread minus the bullet diameter. If you don't want to do the math and your groups aren't one ragged hole simply measure distance to the edge of the farthest holes on the same side

I agree with krochus that I'd never "post" a 3-shot group in order to demonstrate the capabilities of either a rifle or myself.

However, I maintain that if you can take your rifle and shoot a MOA or better 3-shot group consistently when it is called upon to do so, that in itself cannot be discounted.

Although I didn't get a lot of advice, I decided on the LaRue Tactical 7.62mm OSR.

I almost bought the Les Baer 6.5mm SV but decided on the OSR because of ammo availability and price.
 
I would have to say stay away from the ARs, not that they aren't accurate. Just overpriced and hard to get in my opinion. If you want the best get a GA Precision, but expect to pay for it and wait forever to get it. I would upgrade the PTR-91 that you already own. There are guys on HK forum that have put together a group buy for a PSG-1 style target barrel that should easily get you 0.5 MOA with other upgrades (stock, trigger group, etc.). Good luck, Mav.
 
I tried GA Precision, but they aren't accepting any new orders because of the "Obama Mania."

I didn't know there was a barrel upgrade for the PTR-91. It sounds like something to consider.

I like the ARs because I am familiar with them. I agree they are over priced. I don't want to pay 2,500+ for a rifle if something close in accuracy can be had for $1,200.

I was tempted to try the 6.5 Grendel, but the ammo availability and price made me hesitate...
 
I will say that I have toyed with the idea of a 6.5 Grendel. If I owned a AR it would be a must-have. But I don't, so it isn't on my short list. I did recommend it to a friend of mine a few days ago, the following is what I spec'd out for him:
-Alexander Arms 6.5 with 24" bbl
-Zeiss Conquest 4-14x44 AO (highly recommend for a moderate budget)
-Weaver Tactical Rings
-Harris 6-9" Swivel Bipod
-1.25" Outdoor Connection Super-Sling

He wanted a AR that would reach out about 600yds with a decent degree of repeatability. He also wanted something that would hit hard enough (at closer ranges) to harvest deer. Since you already have an AR pattern rifle I would suggest that you convert it to 6.5 using a different upper rather than buying a complete system (assuming you are dead set on a AR, not to say that's bad). Just remember to do the other upgrades like a adjustable stock and Jewell trigger pack to the rifle, otherwise practical accuracy might not improve by much. However, if it were me go with the PTR-91...it will be more comfortable to shoot (for me anyway), deliver .308 that can be had anywhere, and look pretty darn cool at the same time. :D
 
That 25" PSG-1 barrel from Rim Country looks pretty nice, but the $700 price hurts. I didn't think a PSG-1 could be made as accurate as a National Match M1A.

I was going to keep the PTR-1 as a "battle rifle" for plinking with Wolf ammo (since it eats brass), and buy a .308 AR for accuracy. I may reconsider and try customizing the PTR-91 to make it more accurate.

I'm also thinking about buying a 6.5mm Grendel upper since I already have 5 Grendel Mags and a pre-ban Colt lower.

:what: Sorry, but I had to laugh at that. A PSG-1 is much more accurate out of the box (and at about $15-18k it better be), however the PTR-91 (even with the upgraded bbl) will never be a PSG-1, or shoot as good as one, but you can get close for alot less. The PSG-1 has an accuracy guarantee of sub 1MOA and is usually about 0.5MOA. A Nat. Match M1A is about 1MOA summer (summer less, summer not). I am assuming that is what you were referring to. ;)
