Hey guys, So its been a while since my last post, but I thought I'd update my original DMR project post. The build list as of now stands: Gun: KWA KM4-A1 (Old version, I'm assuming as it is rear wired.) Gearbox: -Stock Gears -Stock Motor -M125 Spring (Don't know brand, but around 420-425ish with a .20 -Stock Compression assembly (mostly) -Stock Trigger, Tappet Plate, and trigger sears/connectors assembly -Stock Wires -Prommy Piston and Piston Head -Stock Wires -Stock anti-reversal latch -(Everything else is stock, KWA Makes a solid gearbox) Hop Up & Barrel Assembly -G&G Green Bucking (Flat Hopped) -M Nub (HS5 I believe, great product.) -Stock Hop-Up Unit -Modified Hop Up Arm for the Flat Hop -Madbull Steel Bull V2 509 mm barrel Variables -I run mostly .30 gram bb's, but I am curious about how .32s might work. -11.1 Lipo Battery (Valken) Externals: -AIM 1.1-4 x 25 scope with fake larue mount. -G&P TMR Rail System -Worn externals for "that look" -Krytac Stock for better storage -Madbull Gemtech Barrel Extension -KWA Goodness Questions: 1.) With .30, the tech at my local shop claimed 290 feet. I believe this, but my home field doesn't present many opportunities for uber long range shooting without the interference of branches or bush. Does 290 feet seem about right? Measured on google maps, my gun accurately goes goes beyond a 240 foot benchmark with accuracy. 2.) With flat hop and around 430 with a .2 considered, what would the ideal BB weight be for my gun? I have not tried .32s yet, but .30s have yielded remarkable success. 3.) Are there any further upgrades or mods I should have installed into my gun? Thank you very much everyone, I look forward to hearing from you.
