This would have been the perfect tool......but just like the other reviews state, the front sight tool broke extremely quickly....would only recommend this product if Gerber could fix this issue or sell the front sight attachment.

Sight tool broke in less than 2 months. Called for a replacement and was told that they don't have any. Sheath is also garbage it fell apart soon after the sight tool broke. Need option for no star rating. You would think that a $100+ dollar tool would be better quality but not a Gerber tool.

I have used this tool for years, but yesterday I took it to the zero range and let some Soldiers use the sight adjustment tool, an hour later all four teeth were broken off. I chalk it up to Soldiers who don't know how to adjust their front site post correctly and have Gorilla strength mentality where they think more muscle will fix the problem. Is there a way to get a replacement part? Still love the tool would like to replace that part.

Same experience. Was on the M4 zero range, 1/2 way through, notice teeth were broken off. Replacement part?

I've had it just a little while. I think it could have some promise. But I think for an American made tool it's pretty poor. The instructions say the magnet can be used to pick up small items from the receiver. How's that possible with the magnet in the sight tool instead of the end of the sight tool shaft. Plus the locking mechanism is sloppy. Stores are asking around a 100 dollars for this tool and 75% of it is scrapers. There's a angle scraper a flat scraper which is also a punch a hook scraper another flat scraper which can be a screw driver. And a brush to clean away the scrapings. There's also a sight tool that the teeth break off to easily. Yes I made it sound simplified, but for the money that's basically what you've got. You can also use other tools that fit onto it if you buy them. You see what I mean. Come on, you guys build pretty good stuff most of the time. And your prices aren't usually to outrageous. This could be an outstanding tool but it sure missed the mark this time. Go ahead and mount the magnet in the shaft so it can be a pickup tool. Make the teeth better so they don't break. Yes it's warranted, but what goods that to the man in the field who's half through adjustments and it snaps. He could have his life depending on that rifle, but now his sights jacked up. Make a space for more and different tools that you can attach to that threaded hook attachment. Tighten up the locking mechanism or redesign it. You folks have intelligent people working there. When you build an American tool for American GI's and the American public. Build that sucker as if the soldier depending on your tool is the only one that can save the world. If that were the truth, I'll bet that tool would be the baddest tool on the planet. Now comes the hard part. Making that tool and having a price tag on it that people will pay. One thing about most Americans. If that tool is so good the can't hardly do without it. They'll pay a pretty hefty price tag. But better yet build a GOOD tool and put a decent price tag on it.

Great tool but teeth on front sight adjustment tool do break easily. Loaned it out during annual weapons quals, after just three people I noticed two teeth gone.

Got my first eFECT in 2010 whe preparing for a deployment. It worked great and lots of range days since. After a lot of use the "stub" on the front sight tool flattened out but other then that I am happy about the tool.

Love the tool, however, the teeth for the front sight adjustment tool break easily.

Very helpful during multiple ranges. Lasted two cycles (230-240 soldiers, though I didn't adjust them all) before the teeth broke. Well worth the money

The teeth broke within the first uses of adjusting front sites of weapons.

The first time I used this at range qual I let several Soldiers use it to mechanically zero their weapons' front sight. The teeth broke before the second finished. They were being very gentle with it. I in no way expected the teeth to break. I wouldn't spend the money again.

Very Functional tool however the teeth continue to break on the front sight. Gerber has been very helpful in replacing them though.

Love this tool. Very well made. I was actually surprised when I found it cheaper on this website than other websites I have looked on.

I've been using this tool for a while and I've not had the teeth on the forward site tool break. Maybe I've just been lucky, but I'd suggest putting a little bit of CLP (lubricate) on the front site prior to adjustments anyway. It should make the adjustments easier and maybe save the teeth on the tool as well.

I bought the eFect tool prior to going to a Company Range Qualification Day, to better assist my junior Soldiers in Zeroing their weapons, after adjusting the Front Sight Post on just one weapon, the teeth from the "castl key" front sight post-adjuster broke off. Very dissatisfied.

I purchased one of these tools to speed up the adjustments for other soldiers on the zero range, to help them focus on their shooting and not how they are going to adjust their weapon. The first time I went to adjust a front site, the pins broke off when turning the front sight. The tangs were not long enough to dis-engage the front sight for moving the post up or down. The other parts of the tool work great and provide great functions.

I purchased a eFECT at a PX at my camp and the first time I tried to set my front site the tool failed and the teeth broke off.
I was not happy about the $82.00 dollars that I lost for a failed tool.

Love the tool and how it is interchangeable with Otis tools since they're standard issue. Keeping the weapons cleaning packed and the tools you need quickly on hand on the EFECT is nice. Same issue as a previous comment though, I snapped all the teeth off the front sight tool the first day I used it within the first three magazines of Zero. I wasn't abusing it either, I paid attention to line everything up and not force the front sight around and they still all broke off. Other than that I love the tool and the fact it fits into the butt of the M16 especially since our unit switched back to them from the M4. Good tool, I'd buy it again.

This tool is awesome! All of the builders within our company were issued these for use at their stations. I am a little confused as to why it says credentials needed to purchase this tool when it should be made available to the civilian public so that people like my self can purchase one and have it sent to their house. After all, the AR-15/M4 weapon system is immensely popular amongst today's shooting public. Our marketing department found last year that the number of AR-15/M4's in the public hands (not military or LEOs) is equal to 3 Rifles per person living in America! This is an amazing number and we'd love to get it to 20 Rifles per person in the next two years...but for statistics like this to grow the public needs access to handy tools such as this one made by the greatest Outdoor Knife/Tool company in the USA - Gerber Legendary Blades. Thanks Gerber!

I love this tool, but the teeth on the sight adjustment tool are a little flimsy. All the teeth on the A1 side got broken off and i'm down to only one tooth on the forward sight tool.

I was given one of these to field test. Love it, worked on all or our weapon systems. Have to guard it, the Infantry guys are always looking to steal it.

Looks like a very handy tool. I plan on purchasing one in the near future. I would love to find a multi tool that can make adjustments on the front sight post for M16/M4, M249, and the M240B.
