You would have to use the rifle length super42 spring with a vltor a5 buffer. If the question is about using the vltor A5 system on AR's...

Just went and reviewed my data. The barrels lengths I've chrono'd recently enough to have used a common load between them are: 13.7, 14...

I ended up with a VLTOR MUR upper, VLTOR A5, ADM UIC ambi lower, Geissele MK4 13.5" and Criterion 14.5" hybrid barrel. I ordered the...

Personally, if i was in your shoes, I would NFA the 12.5 and put a 1-6 on it. Then I would get a new hyper accurate barrel for the 16...

Best “one gun” is a high quality medium contour pinned 14.5”. No stamps or braces, no 5320.20s if you live near a state line…. If NFA...

I must not have made it to the advanced classes.

11.5"+3.5"= 16"? Not to mention a muzzle device with a 3.5" oal will only add 3" ish to the barrel length. Never heard of an...

11.5 with a 5" pinned brake/hider? That sounds absolutely stupid.

Never said flex with fanboy parts. If that's what starting over and building something with quality parts means to you then guess I'm a...

The Vltor A5 buffer system is what you seek. 12.5” is my “do all“ rifle. The velocity loss from a 16” is worth it for the 4” shorter...

Also yes, but let's be honest on why 11.5"

X2. Only barrel length you need in 5.56. Regardless of barrel length, that 22cal bullet still loses a lot of energy down range anyway...

Just build another one 🍻

I don't know who the credit goes to for this graph but this should give you an idea of velocities with certain rounds and barrel...

If you have to... ditch the 16" ( other wise keep it for any anti shorter than 16" barrel laws that might be coming down the pike )...
