Modify SSX 6.03 Stainless Steel Tight Bore Inner Barrel for VSR Spec Hop-Up Units
(Length: 430mm)

"Perfect drop in upgrade for SSX303.

Tested with G&G 0.40g over 10 shots, using Novritsch/ASG mk23 magazines (green gas). Bucking was swapped to Modify X-Range 55 deg, but hop was turned off during chrono tests.
Chrono results:
Stock (303mm): 1.6J - 1.8J, avg 1.68J
Modify (430mm): 1.9J - 2J, avg 1.94J

Grouping is similar, if not barely better than stock. Planning on testing with high flow valves, and mag gaskets in the near future.

"I took a chance, and glad I did! Working on a SSG10 Wolverine bolt build. The stock ML 430mm barrel brand new kept throwing curves to the left ( a known issue). I swapped out to a tridos TDC and tried various buckings (flamingo, modify xrange) but they all kept throwing curveballs. Well nothing I did could get the BBs to go straight so I bought a modify barrel and used a Maple Leaf autobot (the OEM bucking), well that solved it. I put 5 BBs .40's into a 4 inch circle at 125 ft (backyard test distance) right off the bat! I was blown away. And it was dead straight. I used the Tridos BLACK R-hop patch that the kit comes with. 2.1-2.2 joules using a HPA setup with 80 psi (the minimum operating pressure for the wolverine bolt). I need to get a shorter barrel now :D to tame the speeds.
