Accuwedge gimmick or useful piece of kit?

Tell ya what r34skyline, Do whatever you want. Just don't be a disrespectful douche.

He wasn't disrespectful in the least nor was he a douche, he just pointed out you don't know what you're talking about.

I, on the other hand, will be a disrespectful douche and tell you to grow some ####ing balls.
 
Here is something from the thread that mebiuspower provided.

It appears that there are more people who are not in favor of using it than those who support its use.
Several have had one break down over time. Not surprising; it's rubber and under tension. If a person wants to keep using them, they may need periodic replacement.
Does it matter if someone uses one? Depends on who you ask. Some will say "whatever floats your boat" and some will be so vocally expressive as to be deemed offensive. Do what you want to your own firearm. Burn it, kick it, treat it like gold, take it to bed with you at night~ doesn't matter. It's yours, so do what you want.
Here is a test done by a member on the link.

I tried to keep it as scientific as possible, so here's the equipment used:

4cm diamond target with MOA grid.
50 yds.
Aimpoint 2-MOA T-1 with the 3x magnifier
COLT M4 rifle
M855A1 rounds
prone supported position (I actually put a bipod on for this test)

I shot 5 rounds with and then 5 rounds without the accuwedge; letting my barrel cool down a couple minutes in between.

The results were almost identical.

Some have chosen to go with the o-ring method of removing the rattle. In my experience, some types of rubber used in O-rings break down after a few years as the rubber becomes brittle and cracks, so regular inspection should be done when the rifle is cleaned. I can't speak for others so, when a cleaning is done, I like to use a flashlight to look inspect the upper and lower receivers for cracks or wear. My 30 years in military aviation and Aviation R&D has shown me that this is a good policy.

What does it all come down to?

It's all about personal choice. We can choose to investigate, evaluate and implement according to our individual requirements or we can be like the Sesame Street (for those who are old enough to remember) aliens going "Yep, Yep, Yep.....Nope, Nope Nope...

Colt canada uses it. It builds confidence in new shooters. I love solid builds no rattle. My iur is solid because of it. Just get one, it costs nothing or I'm sure someone on here can get you one.
 
This link indicates the differences of opinion on that board which is happening on this board. Some like it and some do not just like everything else in the shooting, bike and hot rod communities as someone thinks they know more then someone else.

What you're seeing is not a difference in opinion. There are those with experience who know damn well it's a useless piece of crap, and the inexperienced who don't. And yes a bunch of guys over there know more about the AR-15 than everybody here combined. And guess what, they don't support the accuwedge or it's concept.


What we're seeing here is a hardware solution to a software problem. END OF STORY.
 
Re; the accuwedge, or any other means of eliminating the play between receiver and lower, lets think about this for a second and break it down.
The upper is comprised mainly of the upper receiver, barrel, sighting system, forend and other misc. bits.

the lower has your buttstock, pistol grip, bolt, carrier and fire control group as well as the magazine housing.

When the operator depresses the trigger, the inertia of the swinging hammer creates torque and can cause a slight movement between upper and lower assemblies that is limited to the amount of free play between the two assemblies. Once the bullet begins travelling down the barrel, inertia on the torsional and fore/aft plane will cause the upper to move on the lower as well. Any device that causes this freeplay to disappear will therefore have a positive effect on the point of aim/point of impact interface.
Another way to think of it is; Would you knowingly shoot your firearm with loose sights or would you snug them down?

Which makes sense, but if organizations that invest in and demand performance (like the AMU) shrug and say epoxying or welding upper to lower does nothing measurable...........
 
I just had a conversation with a respected member here who is a serious AR15 custom builder , his opinion is that sloppy fitment between upper and lower effects accuracy , I find that often despite "mil Spec" declarations many companies products are just not close to being within tolerances that make for good fitment with other brands .
They fit but sloppy , some even have a slight Gap , than there is Norinco , I find only the lowers are close to Spec

If you have movement between upper and lower and all you hold onto is the lower, then yes, the release of the trigger can be enough to affect point of aim & point of impact. However, when that bullet is sent it is sent where the sights / scope is pointing it to go.
This is solved by holding onto both upper and lower receiver.
If you regularly shoot from a bipod and sock for example, and don't tend to engage with the upper receiver, a wedge, eraser, foam Plug or a dried glob of silicone will all work to eliminate point of aim/point of impact shift.
 
I have 3 higher end AR's. The first is quite snug, the second has a tiny bit of slop and the 3rd has a bit more.
I wouldn't call any of them floppy and nobody who has shot them has mentioned it.
They all shoot extremely accurately.
If I had to give a reason as to why one may be more accurate than another it would be trigger pull weight or style.
Whichever rifle i put the Geissele SSA-E trigger in will shoot the tightest groups. If Install the Geissele S3G the groups will open up a tiny bit and if I install a Mil Spec trigger with a 6lb pull it will open the groups up even more.
 
I hate to do this but I have to do this.

You better believe if you want to shoot small groups or hit at long distance consistently with your AR you have to get rid of the upper to lower play...As well, you better have a butt stock that has no play on the buffer tube.

A simple way to prove how much POI variance you are getting with upper to lower slop or a sloppy fitting butt stock...Get your rifle on a bipod with a solid sand bag at the butt stock...If your rifle has a lot of slop your not even going to need much of an optic...Now focus the reticle or red dot on a distant object and with your free hand carefully manipulate the upper or butt stock at the points that have slop and watch thru the optic at your POI dance around...If you have a reticle with MOA or Mill markings you can even measure the amount of POI error.

Yeah if you are running and gunning with commercial ammo a sloppy fit means nothing to your accuracy but if you want to bear down shooting match or hand loaded ammo with your AR and want small groups or consistent hits at long range your rifle has to be tight...Just ask Les Baer or JP.
 
^^ then why when they welded the upper and lower together, it didnt increase accuracy? I am sure the welds aremire solid than the accuwedge........

Try what I described and you will see for yourself...You need more then an accuwedge if you want a real tight accurate rifle.

The arms business is big business, outfits say all kinds of things if it suits them and there associates.
