"Okay. So I just received this rifle this morning. It comes with a large and small spring buffer, already installed; I took out the large and left the small in place for a realistic ROF and to enable the bolt lock. Also included are a magazine and basic speed loader.

As someone who has owned several high-end AR-15s, this GBB is the perfect airsoft weapon. 1:1 scale, aluminum receivers, carry handle and iron sights. It was like Christmas came early. Checked out the internals for any possible issues, found absolutely none whatsoever. This rifle has very tight tolerances. The magazine fits very tight in the magwell and definitely needs to be broken in. Weapon manipulation is just like the real thing and extremely satisfying.

As far as the magazine is concerned, it performs flawlessly. No leaks at all. I was skeptical of it after reading several poor reviews, however after testing it I am extremely happy and confident in using it.

I tested it outside, this afternoon, about 15 minutes ago. It was about 68 degrees and cool out. Fed it 5 magazines with .20s to test its reliability and accuracy. It is amazing right out of the box...I had only 1 jam on full auto, which was easily cleared in under 5 seconds. Accuracy is wonderful and I plan on further testing its capabilities. The fun switch and recoil is utterly amazing, and is quite the guilty pleasure!!!

I highly recommend this rifle!!! It is perfection, especially with the Colt licensing and trades; absolutely gorgeous...I'm am planning on upgrading the externals to either a SOPMOD Block I or II kit, not sure which yet...

"This is a great looking GBB Rifle with the best looking marking on the whole-wide world on it! COLT!!

Western Arms / G&P System - Easy to find spare parts and lots of upgrade parts
Bolt locks when mag empty
Easy to find spare mags
As real as it gets!
Good gas compression.


As a GBB nerd, I highly recommend this!

"Great starter gun for GBB. Be aware though that GBBs generally need a little extra TLC than those sewing machine sounding AEGs.

Accuracy is top notch
FPS is adjustable
People get terrified when they hear you
Very real feel and realistic field stripping
Good hop-up
Removable top rail exposes a rail for a scope if you want to DMR

Gotta keep it lubed up
Magazines extremely prone to leakage
Firing automatic could risk a misfire and a broken loading nozzle (one of the only plastic parts of the gun)
This won't cooperate in cold weather
