Yes, but isn't it possible that given the different lengths and sizes of low profile GBs, that the distance between the gas port and the back of the block may vary from GB to GB, which will effectively vary the clearance between the HG cap and delta ring.įrom the hole where the gas tube roll pin goes and forward is irrelevant.
Same goes for a front sight or optic (scope or RDS). If the laser is going to be your primary aiming device, I think most of us would suggest that you don't mount it on a 2 piece non free floating rail. I am planning on mounting a green laser, vertical grip and light onto the quad rail. What you're asking can be done easily, as Diesel mentioned, with the addition of a handguard cap mounted behind the GB, but the low profile GB has to be the same length front to back as a standard FSB or your 2 piece handguard will not fit or fit properly between the delta ring and HG cap. I think we need a little more information, before we can help you.ĭo you have just a stripped barrel? Or do you have a complete barrel assembly with a FSB/GB and delta pack?
#10 FREE FLOAT QUAD RAIL GAS BLOCK INSTALL#
My question is simply if I install a low profile gas block such as a troy on my 16" carbine barrel, Can I use a standard 2-piece quad rail or must I use a free float rail or simply remain with a carbine length rail? Thank you. I am working on my first AR-15 build and have a question regarding handguard and gas block compatibility.
