Awesome, inspiring project and setup. Based on this thread, I just grabbed a Streamlight TLR3 for my trunk gun mounted @ 12 o'clock.

In my opinion forward assist isn't needed. If your bolt won't close under spring tension, you probably have a problem and should remedy it not force the bolt to close or you may cause yourself an even bigger problem.
On this rifle since the carrier didn't have forward assist notches I removed the forward assist from the gun and installed a delrin plug available from ADCO. The JP carrier is as durable as any other carrier (it's made of stainless steel and is IonBonded IIRC twice from speaking to JP). These lighter carriers actually require a little more gas to make them work correctly, on a midlength this isn't a problem. They sometimes will short stroke in ARs with rifle length gas systems and small gas ports. It's all part of the momentum equation (they run out of rearward momentum sooner). This was the whole reason why I shot a lot of Radway Green ammo through it to test for function. The Radway Green I have won't run some of my guns with CAR gas systems. This rifle eats it up.
JP LMOS carrier with key = 6.25oz.
M16 carrier with key = 9.47oz.
Very nice!
I like that lightweight upper. I'm planning to use that same Troy rail in my next installation. I've searched through the entire post but couldn't find any mentioning of the Troy handguard installation method, so here is my question.
Do you need any special proprietary tools to install the Troy rail? i.e. Troy specific barrel nut wrench, etc.
Thanks.
nice weapon
I don't like the Troy wrench. What I do is really grease up the barrel nut with Brownells Action Lube Plus and use a DPMS or Smith Enterprise wrench and torque the stock Troy bbl nut up very slowly starting at 35ft lbs and adjusting the torque wrench adding 5ft lbs each time between loosening. This keeps me from bending the teeth on the nut.
On most I'm finding alignment between 40-55lbs. Just go slow and steady.
The really early Troy barrels nuts were thin like USGI barrels nuts and the last 9-10 TRX/VTAC TRX rails I've installed had beefed up barrel nuts. The old ones were super easy to bend barrel nut teeth.
gotM4,
Who, other than Sun Devil, makes a flat top upper w/o an FA? I'm not sure if Sun Devil has feed ramps in their non-FA upper.
