In this video I show a option to installing a the AR-15 Front Sight Base using set screws instead of drilling the barrel and using standard locking pins. Thanks for watching!

Where did he get that 5 inc handguard at?!
Thanks for the idea, I'll be headed to home depot tomorrow for the set screws!!
I love the creativity but I have a question can I do this without using the gas tube because I want to make a dissipator AR
What cute lil rail is that on the pistol?
what bit did you use to drill those holes? thanks
Dude I wish someone would manufacture these you'd make a killing!
if i put it on my 10.5 inch 300 blackout barrel can i put a bayonet on it?
thanks
What size drill bit and tap did you use. I like your idea and I can't find anyone around to drill the barrel.
this is a great alternative ! here I am researching A2 sights and cringing of the permanent placement.
awesome tip ! thanks man. this makes life 100x easier if you want to convert gas blocks / sights !
Great idea! I'm not a fan of set screws, I always use taper pins, especially on barrels with functioning bayonet lugs but on this short one it's fine. I've had that idea too but often wondered if the set screws would need a flat on the barrel to hold. I knew the side mounted screws would. In fact I can't believe they didn't do that but it's good to hear that the bottom screws are holding well. Thanks!
what size drill, tap and screws did you use on this front site?
Thank you very much, I don't know why I haven't thought of this!
I don't see any pin holes on the front sight that you drilled and tapped .. what kind of fsb is that ?
What size screw did you use ?
how well has this held up? i'm wanting to put a f marked front sight base on mine, but i don't have the base or anything (changing over from a heavy full float rail because i thought it looked cool, yeah, my first ar15 lol). if the armilite clamp on would be stronger i would be willing to go that way, but from what i understand they don't have a sling swivel mount. i want the sling mount.
where did you get the m16 retro handguards.
thats what I did too, I also put a small resting notch on the barrel when the end of the allan screw touches……nice vid
Great vid!!! Great option for those who wanna keep the ar15 sight post or options for a dissipator setup.
Thank you SKI, and many thanks for your advise in the past, your method works great! Ray C.
Nice vid Ray. Keep up the good work…….SKI
just throwing this out there, but I want to do something similar to this. I want to build a dissipator upper but the combinations are not optimal. the barrel I have found is a adams arms melonited 16.5" ultra light barrel. I want to use the standard handguards and a a2 front sight post. if I were to drill and tap, I think that creating a flat spot under the set screw would make it about twice as bomb proof. have you ever filed drilled or machined anything with a melonite coating? I think a steady hand and file will do the trick.
That is a good option Ray if you don't want to do any drilling on the barrel. I have found the same thing, in that set screws never seem to hold on a round surface. In a year or two when I think I am proficient I will have to tackle a barrel project. I have a Garand that somehow never got refurbished after WW2 and it is in good shape except the muzzle got dinged up a little along the line. I am debating just taking off a couple of thousands just to clean it up, but it is within a month or two of when the receiver was made so not sure which one would effect the value more?
