Saiga 12-Tromix Monster chop and perm

Recommended Posts

Finally got it to the indoor range but they only allow slugs. It cycled 2 3/4 IN 1 1/8 oz 1410 FPS  Royal Star slugs on setting 4 of the DPH gas plug with the stock recoil spring. Still gotta get to the outdoor range to see if I can get it to cycle federal bulk pack.


I was happy with the recoil reduction while shooting slugs. I still need to test out 3 inch slugs as well as a variety of other ammo.

Not tryin to be overly critical, but a small correction is needed.  The monster brake was designed by Tromix, but it is sold through CSS. Don't forget that Greg is a business member here, plus a good guy to do business with.  Take a look at his forum add.  You will find a 10% discount code there.  Other than that, it is a good lookin build.

From a glance, it looks like about 13.5" of actual barrel.


I am wondering if part of it not cycling 100% with the Estate is due to the additional weight on the carrier assembly. The vert handle and op rod add quite a bit, for a carrier.
