The TechT
MRTv2 (MASS
REDUCTION TECHNOLOGY) Invert Mini Bolts have been
engineered with efficiency and consistency as the most crucial design
elements. Over the last few months we have tested many
different crazy looking super light bolt designs and had mixed results.
After long months of testing on the field and shooting over our
high precision chrono, we found that using the stock type bolt face
oring as well as having no cuts between the two rear orings yielded
the best consistency and efficiency.
My results found
that removing the stock-type face o-ring and replacing it with a
standard o-ring reduced our velocity at any pressure and dwell by
about 15-30 fps and decreased consistency. We think its because
the stock type o-ring seals in the barrel really well. We also found
that placing a groove between the two rear orings for added weight
reduction actually decreased consistency. Instead of a standard
deviation of between 3-4 FPS with no groove, we got a standard deviation
of about 15 fps with the groove. Weird, huh? We hated that our more
cut down versions didn't test better....but what can ya do. Invert
did a really good job when designing the bolt for this gun.
The MRTv2
are our newest bolts that will produced less kick, peak efficiency,
and great consistency.The MRTv2 offers deeper cuts for greater weight
reduction in bolt the GOLD AND Delrin versions.
The MRTv2
GOLD is 30% lighter than stock, and the MRTv2
Delrin is about 60% lighter than stock.
Currently the
best bolts we have made are the ones you are seeing. If you can
think of a way to better this or any of our products email us as
