Accu-Wedge for ARs

[poak]

So, I was doing a little late night reading in regards to my AR build (yep, still waiting on my Del-Ton order). Anyways, I was reading about Buffer Technologies' "Accu-Wedge". It seems a lot of people have issues with getting a nice tight fit between the upper and lower, but the Accu-Wedge (a $5 part, remedys the problem). Are these things just snake-oil, or should I go ahead and order one for my soon to arrive kit?

you may want to see if you have a "nice tight fit"

Yeah, I figure I could just wait until I get my upper, then decide from there...

I guess I'm just kinda being anal and wanting it to be PERFECT when I assemble it, haha

They're junk. Had one years ago, and used it (briefly until throwing it out) in a DR-200 rifle. Just more pieces of fouling to deteriorate and jam up the inner workings (just like the plastic seals that you can get that go under the trigger group), IMO.

Save your money. Most guns run smoother with some play between the lower and upper receivers, anyway.

Cool, I'll save my $5.

I have a JP Tensioning pin in mine to take up some wiggle the down fall is you need an Allen wrench to take it down now.

I have a few of these and they do what they advertise.

[Guest sling]

Yeah.. they do do what their advertised to do. Its just a little plastic wedge that smells funny.

I had to shim some of the plastic off of it though just to pin my upper back on...

[Guest EasilyObsessed]

I have one for all of my AR15's. Does nothing to effect the functioning, but it does take some of the rattle out of the guns.

[poak]

Well, it seems some of you have had a positive experience with the wedge.

Hmmmm... with it being a $5 part, maybe I'll order one when I need something else...

[Guest sling]

Whats sad is the current AR part whoring has even left most places out of stock of those as well.

[Guest Verbal Kint]

You can use an old recoil buffer, and trim it to fit, to do the same thing.

Hell... you could fold up a piece of paper several times and get the same result. I'll stick to my opinion that they're junk. But to each their own.

Another interesting piece of reading : http://www.armalite.com/images/Tech%20Notes/Tech%20Note%2055,%20Receiver%20Tightness.pdf

[poak]

Thanks for the info Verbal, I think I might give a DIY solution a try (but I'll wait until my rifle kit arrives to start experimenting). I know I've got a small block of Delrin around my house somewhere (hope that isn't to hard) that my Dremel could go to work on.

[Guest GUTTERbOY]

Something like this never even occurred to me. Hell, I have difficulty getting my upper and lower together without needing to cram anything in there. I suspect it'll loosen up after I throw some more rounds through it, but for now it's plenty tight.

[jeffmem]

Should be more like 3 for $5 ...

Buy a lower that has a tension set screw and you dont need that little rubber POS

Speaking of which, got more Tactical Inovations lowers in yet (those DO have the screw, right?)?

That's the lower I think I'll be using for my SPR build...

[Guest Verbal Kint]

Sun Devil billet lower receivers also have the tension screw. Very nice pieces, IMO.

I have 100 more inbound from them, along with another 150 from Spikes.

I heard a little rumor that there would be a little company in middle TN. that will be featuring billet machined lowers on their rifles in the very near future

Yeah... think that thread is around here somewhere. But you might have to dust it off.

I'm still waiting on the Mug o' Death.

Battle Mug is a go.

Our team is traveling Friday to seal the deal with the CNC and anodizing facilities.

I hope to see the first 100 mugs available by SHOT 09.

[Guest Verbal Kint]

Cool... I want one. Wife shook her head at the idea. But that just sealed the deal and made me want one even more.

Out of curiosity, do you guys do the design work in-house, or have you contracted someone?

It was all done in-house.

I conceived the concept and design, and my machinist hand turned two prototypes.

We did send it off for CAD, but other than that, its all HG.
