I've got a Noveske N4 Recce 16" with VIS and a standard Front Sight Post. The rifle is a build I would say is near perfection, however, my only wish is that I had went with a low profile since I use an Eotech with 5x Magnifier.
Just a few questions / thoughts, I would love feedback because I'm really on the fence here:
1. Has anyone ever ground down the front sight post? I talked to Noveske, and they said you can't have the gas block replaced (well, shouldn't since they stake it for reliability and a low profile gas block won't properly cover the holes from the front sight post - they did recommend grinding it down as an option) I've seen videos on YouTube about doing this, and it really seems like a non-issue to do, but I do have concerns.
2. Since I have a 16" that has the VIS sized for the front sight post, it obviously will fall a bit short of the front sight distance if I used a flip up front sight on the rail. I'm aware this is only for BUIS (that realistically, I shouldn't ever use unless there's an emergency), but does this loss of length drastically affect the accuracy of the BUIS or is it really a non-issue. Part of me says it really wouldn't matter that much, especially that this probably matches the length of a 14.5" barrel's sight post diference.
3. If I did grind down the post, is there any product I can order to refinish or cover the bare metal I will expose after grinding the site off?
4. Is this a completely ridiculous idea and will destroy the value of my rifle if I ever wanted to resell? I know it will depend on the buyer, but I don't want to take a $2200 rifle and make it worth $500 less because of the lack of a front sight post. It seems to me, it would more easily sell as a cheaper option for a low profile / flip up front BUIS setup.
Any thoughts would be greatly appreciated. Part of me says go for it (improve the performance of my optics that is what I primarily use), another says you don't touch a Noveske and you live with it. That being said, there's no budget for a new rifle in sight in the near future, so I'm trying to set this up as perfectly as possible.
Thanks in advance for any feedback or ideas.
