The bench says Level 2; the parts don't. The semi automatic body can't be researched at all, and a metal spring waits for a Level 3 bench, so on the evening your Level 2 bench goes down, every SAR you make starts with two parts you found. Road crates, dead players, a recycled pistol: box both from day one.
The rest is cheap. Most of the bill is metal fragments, which any furnace turns out, and the HQM barely registers. That makes the blueprint one of the first a group buys at Level 2, ahead of the semi-automatic pistol that wants the same body.
Once Level 3 stands, think before the next body goes in here. An SKS takes the same part for fewer fragments, more HQM and a second spring, and it wins the fights the SAR loses at range.
