宮川ゴム - 東京の下町工場で作られた最高品質のエアソフトガン用カスタム部品をテストしてみた。[Latest Japanese Airsoft Bucking Testing]

In the process of testing many products from a Japanese manufacture for airsoft buckings. More content on this and an explanation video on why coming soon. Testing for both for AEG/HPA as well as GBBR which includes the TM MWS and VFC M4 GBBR Systems.

Brief shooting tests were split into two sections, the typical 350fps for indoor/CQB Fields, and the mostly standard 400fps for outdoor fields. These two FPS limits were measured with a 0.20g bb. See below the chrono results for each test. The Flat Hop Bucking did not go through a break in period. I was also recording and shooting at once, so the HPA rifle may be moving slightly as shoots are fired.

Outdoor fields typically do not have a bb weight restrictions as long as the initial FPS Requirement is met (400fps with 0.20g BB). However, some fields may measure in other ways.

Indoor or CQB fields/arenas typically have a max of 350 FPS limit and are usually restricted to only 0.20g bbs, or in some cases 0.25g.

From there, the first shooting test was using 0.32g tracer bbs at roughly 100psi. The second shooting test was using 0.25g tracers at roughly 80psi.

Shooting Test 1 Chrono Results (0.20g ~100PSI)
Currently still looking for my data sheet. However, the 10 shot group was an average of 400fps with roughly 100psi. Using the 363mm EDGi inner barrel.

Shooting Test 2 Chrono Results (0.20g ~80PSI)
Currently still looking for my data sheet. However, the 10 shot group was an average of 350fps with roughly 80psi. Using the 363mm EDGi inner barrel.
