| What I have; 9mm upper, TROS 5" 3 lug barrel, complete BCG and a SWR Octane 9 HD suppressor.All I need to attach the barrel is a barrel nut, correct? And is there a 9mm barrel nut or are the barrel nuts universal? What forearm is good to use where the suppressor will work? I like the look of the Daniel Defense 4.0 lite rail but I can't find them anywhere. Any recommendations on other short rails would be greatly appreciated. Thanks |

As Killerb6 said, the nut is usually specific to the rail, and would come with the required parts. Some rails use the "standard" barrel nut, in which case you'll have to buy the regular nut separately. I have that same barrel and suppressor and use a carbine length YHM diamond rail with it.

Quoted:
and you will need a rail with an I.D. large enough for your suppressor. I went down this road with my 5.56 SBR. I got the Spike's Tactical BAR and shoved an AAC M4-2000 partially under the rail. It gets hot QUICK. It looked cool as hell, but functionally - not so good. I replaced the rail with a shorter one and got my barrel cut/crowned so that the supressor just snugs up to the end of the rail - but doesn't slide inside. After getting my heat buildup lesson the hard way with the 5.56 - I've decided build my 9mm SBR the same way. I've ordered a 10.5" YHM barrel that I'm going to have cut down to about 8.5" so that it perfectly matches my 7.5 Troy rail. I a .22lr upper with a Daniel Defense rail and a Silencerco Sparrow tucked underneath, now that combo is tits! Obviously you don't have the same heat build up like you do with 9mm and 5.56 so I'm able to get away with it. |
