Will this work in an Arsenal SLR-95 w/milled receiver?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on January 27, 2023

The Fostech Echo AK-47 Trigger 4702 is designed to work with Stamped AK47's. It can work with milled AK47's but some adjustment or fitting may be required. That particular rifle is not listed as being compatible so fitment cannot be guaranteed.

Does the Echo fit a Zastava M70, without drilling or machining?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on September 09, 2022

Due to the different specifications between AK variants there may be a need for adjustment to get the FosTech Outdoors Echo AK-47 Trigger to fit in a Zastava M70. I recommend contacting Fostech to confirm compatibility.
