Please fix your Unity risers and mounts. ### 5/5 — Great app *2025-08-14, version 10.21* Only issue I’ve had is you can’t mount anything to the top rail on the Burris Pepr scope mount. ### 4/5 — Unity tactical glitch *2025-08-13, version 10.21* This is an amazing app, I have never seen anything like this before. One thing I wish was fixed with the unity tactical magnifier mounts. They don’t operate whenever I click the operate button, and one of them mounts in the air! Please fix this. ### 1/5 — Trash *2025-08-12, version 10.21* I had this idea and found this.. You can’t really do anything on the app you can’t really build what you wanna build they don’t really have all the products it’s clunky… not worth the try ### 3/5 — Good but incomplete *2025-08-02* It’s definitely good for visualizing builds to see how components will look together BUT there are a lot of missing mounting options, and components components, and some pieces just straight up don’t work. For example: there’s a 9.5” geissele mk 8 rail, and a 15” but nothing in between. The Unity FTC won’t attach to a rail at all and a magnifier won’t attach to it either. If you want to use a flashlight, your only option is pic rail mounted, because the scout lights don’t have any other mount so they’re just there for show. I would love if these issues were fixed it would make this app so much more useful! I would rate 5 stars if they just fixed these issues! ### 4/5 — Best rifle builder out there *2025-07-07, version 10.21* By far the best way to visualize a potential gun build. It is super convenient and I can easily get an idea of how my projects will look like. I would give it 5 stars but I do find some things lacking. o The latest Glocks modeled are GEN 4 Glocks o The lack of the Glock 45 o No pistol compensators besides the strike industries one o The lack of Holosun products. Holosun is a pretty well established company and I know many people would love to see it. ### 4/5 — great app *2025-06-26, version 10.21* i love the app, but the attachment configurator doesnt work on mobile. please fix this :) (edit: the attachment config works, but its really buggy and sometimes doesnt work) ### 5/5 — PISTOLS *2025-06-17, version 10.21* This app is awesome I don’t have one complaint other than lack of selection but that fur sure takes time but can we get more pistols -1911 -M&P 2.0 -Walther PDP can we also add more modern opticts and increase addvertiesment all so add gen 5 and 19x shadow sistems parts zev and p80 options ### 4/5 — For the developers *2025-06-10, version 10.21* Can you possibly add some more guns next update like 2011s or some more rifles even some more SMG and DMR’s it would be great and appreciated ### 5/5 — It’s the best gun builder game but we need new guns *2025-06-09, version 10.21* It great but we need some sniper rifles like the sig cross, and 50 cal and we need some new pistol like the colt 1911 , sig m17x , and some new assault rifles like the mark 18 , M4A1 , M4 ## Frequently asked questions about GUNSTRUCTION ### What is GUNSTRUCTION?
