I Picked up these 3 guns from a sports shop..They had $30 on them
a we bit damaged...IE missing front site / Broken front site & rear site
adjusting wheel broken...So I got them for $25 each since I took all 3.
They shoot real well....The action looks like a B2-1 with a diffrent stock.
All they have on them is ...Stirling 4.5mm / made in China.
Are they a b2-1 by a diffrent name....but either way they are a bargan.
