Accuwedge use poll

[Stevo]

Yellow foam ear plug. Nuff said.

Me too. I find the ear wax on the used plug lubricates the pin too.

My early 90's Colt A2 is pretty tight and doesn't need one. I've never used one either, but have heard that using a buffer like this can reduce wear on the receiver pins & holes and prolong the life of the gun. Anyone able to substantiate this? Should I start using one on those grounds?

 

[Shelldrake]

Tried it for awhile. Made it difficult to separate/lock the upper/lower. No change to accuracy or shooting performance. Smoke and mirrors gimmick is my opinion.

Ditched it.

Useless piece of crap.

In fact, it's all the opposite.
the accuwedges that the army put in our old beat up C7A1's (in order to reduced the rattle between upper&lower) is actually making much harm to the guns... why ? because the very gentle army dudes are using all sorts of crude devices (gerber multi-tools, cleaning rods, etc..) to pop out the takedown pin when the accuwedge is in place... hence scratching the receiver and crushing the pin :roll:

I purchased one for my AR (BM lower/ Armalite upper).
Firing with or without made no difference...
so I ditched it.

Same with the "new" C7A2's and the new (real as opposed to fake new) C8FTHB's
Most troops have ditched them -- but I've seen a bunch leaning into the C79A2 to close them with the "buffer elastrometric" inserted

I diddn't need a accuwedge, When I broke the pivot pin and take down pin on My C7.
CF expects to have them back when you return the gun, Pff heres 3$ for the useless piece of ####e.

 

[Hungry]

I've got them , but I don't use the little wedges. For my Bushy lower with DPMS upper, I don't need one ....

 

[89crxtech]

i bought a colt sporter from a fellow CGN'er and it came with the 'wedge. i tried shooting it with and without the accuwedge and noticed no difference and since reading and talking about this wedge with other people i am no longer using it.

 

[Savage]

Unecessary and PIA to strip and assemble rifle using it.

Very true and the claims it increases accuracy I find hard to swallow

 

[SA85M1]

Never used one,don't see the need for it...

 

[y2k]

Upper - Lower reciever rattle, like any rattle just gets worse with use. But each to their own.

 

[G37]

you can use a knife to cut down the accuwedge so that it doesn't need a hydraulic press to force the upper on the lower, if the wobbling bothers you.

I can see both sides of the debate. The accuwedge is definitely not necessary, but...

Excessive play between the upper and lower "to me" would equate to more wear over time as evertime the rifle is fired there is going to be hard contact at all the loose points. Show me any machine which has play at moving points that doesn't have accelerated wear when compared to the same machine where the play is virtually not existant (this is why we have tolerances to begin with). Now, we should also keep in mind it probably takes thousands of rounds for the wear to become noticeably worse so this all might be moot anyway. Also, as mentioned, having to force the take down pin to either open or close the rifle every time is also very bad for the exact same reasons posted above.

Think crank shaft and connecting rods in a cars engine. These have to be within a specified set of tolerances otherwise there is premature wear (both too tight and too loose).

The solution posted by greentips (custom fitting the Accuwedge) would seem like the best all around solution. I would want my take down pin to go in easily with very slight hand pressure being applied on the upper and lower.

My 2 cents.

 

[koalorka]

Nah, my RRA is tight enough.

 

[Dsiwy]

There great for target shooting but cause more greif then there worth for combat troops. Theres nothing worse then seeing pte. bloggins smash the sh*t out of his lower receiver with pliers to push the rear pin out.
