12 Standard Size Nock .244"-.246"

First, I'd like to say that overall this is a great product. It's well made, and works exactly as described...with a few catches. I ordered four packs total, three packs of G nocks, and one pack of S nocks. The G nocks seem to fit loosely in my Victory VAP shafts, and VERY loosely in both my son's sets of Easton Inspire shafts. So loosely in SOME of the Easton shafts, that I had to wrap the nock shank in a piece of black plastic bag to get them to stay in. Now...I understand completely that this is a consistency issue with the arrow manufacturer, as switching nocks around didn't change which arrows were loose. That said however, no other brand of nocks I've purchased had as loose a fit, and some brands (both F and G) are actually quite tight in the same shafts. The S sized nocks don't seem to have this issue with my daughter's Victory Venus arrows.This brings me to my second issue. That being that with lower poundage bows, the 'hooks' don't seem to disengage as they are supposed to. My boys shoot very low poundage at this point at 19" draw and 18 and 20lbs, and my daughter is at 32lbs and 25" draw. Once I got the nocks to stay put in my boy's shafts, I noticed drastically poor arrow flight (the arrows leave their bows quite slowly at that low poundage lol) both coming off the bow, as well as down range...with all of the poor accuracy associated with it. Switching back to the factory G sized nocks for the arrows corrected the issue. My daughter had the same problem at 32lbs as well. I however, have no issues with my 62lb, 27" draw Xpedition Xcentric. Even with the 'looser' nocks, arrow flight is clean and the release crisp.Anyhow, all of this said, I'd definitely recommend this product if you are an adult shooter, with something over 30lbs of draw weight. The slightly looser nock fit in my VAP's are actually a bonus, as I made my own lighted nock assemblies, and being able to pull the nocks out makes them very easy to shut off.

You can definitely hear and feel the difference. The strings don't vibrate into the riser as much as with normal nocks and when the arrow leaves the strings I no longer hear that whipping snap sound! It just sounds awesome! Definitely hesitant to buy this but not regretting my decision a single bit. I bought the blue and pink color because they seemed easy to find in case you're shooting in the woods. I have leaves everywhere and it made it so much easier to pinpoint.

Pricey, but looks good! (Hot pink arrow wraps, pink Starrflight FOBS, and these) Stick out like a sore thumb in nature!!!Didnt really notice any difference in shooting, but honestly just bought for looks anyways. One of the inserts did come out just yesterday. I popped it back in pretty easy so we'll see how it holds up.

There seems to be a production/quality issue with the interior (Delrin black) component of this nock. They WILL break much more than you would anticipate. I have at least 3-4 per dozen with broken interiors - after no more than 2 to 3 shots of each. My application is not unusual - 64# of draw, 29.5" drawlength and vapor trail strings. The good people at Accunock seem willing to replace broken ones, but only .... after/during your next purchase :-(. They also seem to stock-out of some desirable combinations, such as Black within Smoke.

I can't believe these have the rating they do, no added silence to my bow, no added speed, not durable at all and most disappointing is their accuracy, they have a chance to majorly throw a shot off randomly by breaking on you as you shoot themSo here is my experience with these guys so far. I'm all excited to get them in the mail and they arrive on the early end of their estimate even. I put 3 of them onto my gold tip hunter xt arrows and leave three with the ones jacks outdoor gave me for free when I purchased the arrows, they fit perfectly and look great. I am very pleased so far, now to the testing, first at 50 yards. I shoot my groupings both groupings are very similar and very tight, tighter then things that won't fly on amazon reviews.Spreads were:3" 5" 6" 3" on my free knocks5" 3" 4" 16" for the accuracyYou notice that last number there? Well there was a reason for that, the knock engage didn't on one of them and sent it way to the left, when I got to the arrow I noticed the knock had lost its insert. It ruined my shot and broke itself by not letting go of the string after 4 shots!! I found the insert and put it back in but it had a tiny bit missing kept coming back out. AND there should of been plenty of speed and force coming from my string to make it engage. I shot these out of a 70lb pse omen xforce bow. The omen models have always had a cam design and draw cycle that will make it the worst 70lbs of string you will ever pull back but reward you with impressive speed and massive kinetic energy... So yeah, not a problem with a lack of pressure on the knock.Bottom line is that these are trash, you don't want to have this s*** break on you and fly off somewhere random at a critical moment and my free ones performed just as good without even including the shot that flew off target.Ok so they are pretty spiffy looking.But they don't quiet your bow down.They are delicate and WILL break.They are not accurate.Epic fail

Several nocks broke during just the second Vegas shoot (separate targets). Don't waist your money on this garbage. Potentially dangerous to shoot. Note: I'm only shooting 60 pounds......

I thought the black and red would look cool with my bow but you cant really see the black unless you study them very close. Nothing like the picture.I haven't shot them yet.

These are the best nock made !
