I'm looking at two different uppers to finish my build, and would appreciate the inputs of the experts here. I'm open to other options as well, but have worked with this seller on some other parts, and he's been great so far.
Option 1:
M4A3, 16", mid-length, $740 depending on other options (sights, flash hider, etc).
Custom M-4 A3 with UTG Quad rail - Top Notch Top Ends Store
Option 2:
Custom MK-12, 16", full length, price a little over $1000, depending again on options.
Custom MK-12 5.56 - Top Notch Top Ends Store
Purpose: General self defense and shooting range entertainment. I'm not joining the militia and planning on burning 10,000 rounds/month in combat training, and I'm not planning on routinely engaging in close-quarters battle with trained soldiers. Is the full length system worth the extra $300ish? Or should I be spending that $300 on pushing my BMW farther down the slope to being a full-on track car?
Thoughts?
Thanks in advance,
Dan
