Question: What is the diameter size that this slides into?
Document: this product is very cool looking but doesn't fit my free float quad rail not knowing that its design was for a pacific rail, I can modify it to fit and that's probably what ill do, just shave down the lower rings paint, and maybe some jb weld or hopefully find some bigger screws, other than that its pretty awesome, and be carefull of the spikes they are pointy.
looks good does exactly what is sais its supposed to. i would reccommend it to any one with ati forend
This is a quality addition to the ATI eight sided forend. I put this on my 6.8 as it may be useful to make a solid rest off the side of a tree, but mostly to keep branches, leaves, and other debris from getting between the barrel and the forend while out in the field!
I wanted something a little different as all my AR's were outfitted with Magpul so after many reviews I decided to take a chance with Advanced Technology. This nose cone was the final touch to a mean looking outfit. The material is extremely sturdy and fits into the forend very nicely. Just a side note. I had to remove my gasblock and tube, put the nose cone on, then put the gas tube and block through the nose cone otherwise the cone will not look straight
I order for a build for my brother ar15 pistol and it made it look nice . I have  one more to do and my other brother is looking at the same nose cone if you use any other handguard other than ati you will have to modified it or the handguard . but over all it make good look
I contemplated purchasing this end piece but I am so glad I bought it. As all ATI parts, it's awesome and looks so good on my AR 15 which I custom built. I would highly suggest if you have an ATI free float barrel to make sure and add this to the list.
Constructed well and probably works great with an ATI fore end, but that is all it fits, I wish amazon would make that more clear in the description.UPDATE: I have recently purchased the ATI fore end and this fits great! Looks nice and fits tight. Definitely worth it to get the the set!
Answer: no
