Heavy Metal Airsoft talks about these outer barrels for Hi-Capa GBB pistols from Sanctus Customs. These have 1mm+ internal threads for use with suppressors/tracers. They have non-tilting/non-shifting design; the outer barrel is fixed and does not shift like the stock outer barrels... "After 4+ years of use and abuse I can say these are the best bang for your buck!"
Some airsoft players gleefully installed the Wolverine BOLT M HPA Engine on the Silverback Airsoft SRS A3 sniper rifle after it got released. Heavy Metal Airsoft shows you how easy it is to install it... "Installing the Wolverine Bolt M HPA engine in my Desert Tech SRS was super easy and really the ultimate upgrade for this replica."
Heavy Metal Airsoft shows how you can install a folding stock for an AR-style AEG using the G&P Folding Buffer Tube Set for M4/M16 Series Airsoft AEGs which is the v Strike Industries Viper CQB version for airsoft... "This Is A Repost, The First Video Got Messed Up After A Re Edit And Was Just Shyt So."
Heavy Metal Airsoft took upon himself into doing a video showing how to install the Redline Airsoft Gen 2 Airsoft to help others... "I looked for this video before buying this, but I could not find one. I installed the airstock myself and thought you would like to see how it works also."
