Another Great option are the Micro Master 20mm guns. The detail and crispness of these parts are incredible:
What can I say but highly recommend the Bunker Studio 1/700 USN 40mm quads and twins. Nicely printed, captures the detail including surrounding rails. 40mm quads come with shield and without. 40mm twins with open railing and solid railing. 8 quads per sprue and 12 twins per sprue. In black resin which could be a problem for lighter paints.
With the demise of 3D Model Parts and the three part assembly challenge Fine Molds offered in 1/700, nice to just paint, cut sprues away and install. No more cutting or bending shields to fit the quad mount or the intricate process of installing guns in the mount. Best no more stupid placement of attaching sprues to the detail you just purchased. Cut the sprue and lose the detail. Bunker Studio seems to have given some thought to this for attaching sprues are from beneath the piece.
I wish I could give praise to their 20mm singles and twins. Excellent printing and superior to that of Blue Ridge but they do have a fatal flaw. They placed sprue attachment points on the shoulder harnesses. Too much stress in cutting away those sprues and you lose the shoulder harness. Even the Fujiya cutters would have a problem with this. But same could be said of Blue Ridge who put attachment points on the crew footings of their 1/700 1.1s and 3”50s. So I guess hobbyist choice if the detail is worth the effort and expense in 1/700 scale. Myself I will stay with the 20mm singles and twins from Blue Ridge. 2 attachment points and none in a critical position that you will lose detail.
In my humble opinion Bunker Studio raised the bar in 3D printed weapons and will be tough to beat in quality or simplicity. They would be a power house for 1/700 USN hobbyists if they corrected their 20mm single and twins attachment points.
Waiting to see if they will offer 3”50s 1.1s, 5”25s and open mount 5”38s in 1/700.
