Guys we are adding different profiles as well as working on conversion uppers on top of keeping up with normal demands. We are trying our best to add more stuff and different profiles. We have added in the past few months 20" Gov't profiles, 20" LWs, 16" Mids LW, and 16" Mids in 1x7s. These were all requested by our customers, so we delivered. It is just a matter of time before we have a different profile, but keep in mind that there is a little more involved in the process.
So, I took a few minutes this morning and weighed some things ALL IN LBS, +/- a few thousandths...
You can use the VLTOR VC-1 on your 14.5" barrel, but it has to be pinned/welded. Using a A2 Flash Hider pinned/welded on a 14.5" will be under regulations.
Standard birdcage A2 hider weighs .1270
VLTOR VC-1 weighs .1278
YHM Phantom 5C2 weighs .1328
I then weighed a 16" M4 upper with standard options, which BCG and charging handle = 4.0164lbs.
Then barrels with just the FSB (no guts), HG cap, and barrel nut...
14.5" M4 barrel =1.9894
16" M4 barrel =2.1424
16" LW barrel = 2.0068
16" H-barrel = 2.5608
16" MID H-barrel = 2.6736
16" MID LW barrel = 2.0348
20" H-barrel = 3.2656
20" LW barrel = 2.3788
20" Gov't profile barrel = 2.5820
Hope that helps!
