whats the best free float rail that uses standard g.i. barrel nut

[jstalford]

The longer you go, the more apparent the short comings of the gi nut are.

i built an upper, decided to switch to a different barrel and gas block, but, the set screws in the lo pro gas block stripped like a mofo, im just to lazy to start messing with the gas rod pin and rod just to get the barrel nut off to swap barrels, just gonna keep this barrel on the upper now until it shoots out.

The G.I. Barrel nut really limits the choices on rails.

Drilling the screws out or even cutting off the gas block and replacing allows the installation of your favorite rail.

It's really not that hard to make it right.

Any good armorer should be able to accomplish that if you send it out.

And if you can't find help in Tucson you're not looking very hard.

Go with the Fortis rail, it is GTG and should be available in longer sizes iirc.


ETA- here it is in 14”

i kinda disagree with you, i prefer 15'' because when i clamp my rail with my support hand, its pretty far down the rail, i have long arms and hands, so i hate canting my elbows for short rails. also because when i brace my rifle on a vtac wall or objects, i dont affect my zero

You want a good 15" rail that uses the factory nut, with solid lock-up, that "doesn't cost a fortune".
So, just curious why no love for the 15" Samson Evo I posted on page 1 (@ under $155 shipped)?

I've been tracking this discussion and want to confirm that if I want to put a rail instead of traditional handguard on my OEM-1 Colt 6920 upper, without having to remove the front sight, bayo lug and sling attachment my best option is a C4 Centurian rail? Correct?

Yes and no. If you do not want to take it apart you will need cut off the delta ring assembly and front handguard cap, if you do not wish to destroy those parts you must disassemble it.

OK, I've got no problem with cutting off the Delta ring, cutting off the spring, etc. Is the front handguard cap also easy to cut off with a dremel? I'm more concerned about the bayo lug and sling mount.

You want to be careful not to hit the gas tube, I'd recommend tin shears on the cap. You do not need to remove the bayonet lug, the sling swivel is easily removed with a pin punch.

I am pretty that the SIONICS shop could help with that.

I kinda over looked it but since it's adaptors are able to convert to keymod or mlok I may try this out ! Can't beat the price
