My first AR15
Tweaker
Member Posts: 19 ✭✭
I recently purchased a complete Bushmaster 20" HBAR. I want to try a Bushmaster 16" HBAR upper. Will my Bolt Carrier Assembly drop in without any adjustments?

I am not sure how that relates to my qustion?
No offense meant, but where I live a Tweaker is a hard core Meth user, that nobody in their right mind wants to see running around with anykind of a AR. To have somebody call themselves a Tweaker, has a very negative connotation. Almost like their proud of it.
When you change that length you change the amount of pressure going through the tube. The three ways this is dealt with is "pig-tail" gas tubes, different buffers and drilling the gas port "DON'T DO THE LAST ONE!"
Dropping the 4 inches of barell may or may not cause you problems. Try it out. If you have function probs, this is why. Good luck.

I'd rethink an HBAR anything. They convert a neat lightweight carbine to
a heavy, unwieldy clunker.
You can get excellent accuracy from a medium weight 16" barrel and still have the handiness the AR was intended to provide.
I trimmed the barrel under the handguard of a medium wt SS 16" OLY to the same diameter as the front of the barrel and still get beautiful accuracy in a lighter gun. It's not much heavier than a featherweight barrel but much more accurate.

Neither bother me. As a hobby, I tweak many things for better performance. I'm saddened to hear another good word has been poisoned.
