I just picked up the AFV M1134 Stryker (ATGM) kit #AF35134 and am looking for recommended books, photoetch or resin upgrades that are available.

Voyager make a PE set for it,they also have lenses.Etmodels make a wheel set for them as well.

This is a great book:
STRYKER MGS IN DETAIL: STRYKER M1128 MOBILE GUN SYSTEM
Zwilling, R.
Published by WWP, 2009
ISBN 10: 8086416933 / ISBN 13: 9788086416939

Eduard do PE sets.
Real model do resin wheels, multi-media stowage sets and updates mainly aimed at the IFV but may be of use on the MGS.
DEF do resin wheels.
AFV club do an accessory set. (basically a repeat of what's included in the kit)

Enjoy it's a great kit.

Thanks for the great input. I ordered that book and also the Eduard giant pe set.

Now to just get my workbench back and start back into the hobby after a few years of Life Got In the Way!
