Custom-built drum mag for VFC Scar-H Gas Blowback Rifle made by me. Incompatible with AEG SCAR-H or WE-TECH SCAR-H GBBR. Compatible with VFC SR-25, VFC M110 SASS, VFC M110K1, and APFG M7 GBBRs. Intended for the CoD HAMR replica build. I dislike TAPP Airsoft product (shown to destroy guns and have bad QC), and no other reputable company makes VFC Scar-H HPA drum adapter, so I made my own and decided to sell my work. Taken from a regular metal 30rds VFC Scar-H magazine, cut in half, and welded a metal plate and Angel Custom flash drum together. Durable, tested to hold at 150 PSI+ (maximum output of my own regulator). Zero leaks, zero jamming, zero misfeeds. Accepts any standard US-spec HPA lines and regulators. $120 for materials (including mag and drum) $90 for labor and shipping (free shipping to only USA) Will drastically reduce the price if you ship your own mag or drum to me. Expect ~1-2 weeks to account shipping time, build time, and testing. Will regularly update progress. Feel free to contact me for any questions. Will try to respond within 24 hours. Will try my best to answer any questions. Can accept custom modification order (electric vs. flash, other drum brand, different color) Magazine damages will be covered and repaired as long buyers pay for shipping for 60 days after receiving the drum. Depending on the damage and its cause, the buyer may also be subjected to pay for material, but it would be evaluated case-by-case. Keep in mind I am an independent builder, I would not be liable for other damages that are not the drum.
