Very good for visualizing a build

This app is well thought out and it is very helpful for visualizing how a build will turn out. For the developers: Of course, there is always room for improvement, so I have a few feature requests: 1) You have already added canted iron sights, but I would like to see a canted mount for small RMRs and red dots. 2) I would like to see a couple of AR-15 uppers from Cobalt Kinetics, as they have these elegant double-sided forward assists, where there is one on each side of the rifle. This is incredibly helpful for making your build ambidextrous. 3) Hera Arms CQR parts for AR-15 4) Railed top covers for AK builds. The new series of Kalashnikov rifles have railed top covers and better handguards, for example the AK-12 in 5.45 and the AK-15 in 7.62. I would love to see more options for those. 5) Official parts from Kalashnikov USA. Having USA made AK parts would be incredible, and even being able to make the Kalashnikov USA shotguns would be superb. 6) New weapon platforms. I would love to see a 1911 or 2011 handgun platforms as well as a revolver and some sort of bullpup rifle platforms. Thanks for reading, and I do hope to see these features added soon.

The app I’ve been looking for over literally 10 years

I was told yesterday about this app by my buddy, who is a avid gun enthusiast like myself, and I have to say, I am very impressed. I’ve always loved apps that let me customize guns, but they rarely had the option to buy what you built, if they did, there weren't a lot of options. This solved that by including a great amount of products to choose from. On top of that, it lets you know if said products are compatible or not, which is fantastic. I definitely bought the full version so I could make multiple builds, I feel it was worth the $2.99. That being said, it’s 100% perfect, but nothing is. There are a few things that I saw that were off, like putting a flashlight attachment on some of the rails would look like the textures are clipping, which would mean it wouldn’t work on the real thing without moving it. Also there was some weird thing going on when putting some of the fore grips on, it would say it’s not compatible, even if was in the middle of the rail, but then I moved it slightly and it would work. Also when putting some attachments on a modular rail, it would clip through but still attach. Small things in my opinion and certainly not stopping me from using it. Love it and hope they add more products to work with.

Best so far (updated dec 2020)

Great game super detailed customization, and the accuracy of the build aspect is great. I like the variety of parts but and lots of the glitching has gone away with the new update but it’s still not perfect and more in some of the smaller categories wouldn’t hurt. Quadrail options are lacking. The variety of build platforms and calibers has improved but some of the unique calibers are lacking in parts selection and at least one shotgun such as a mossberg 500/ Remington 870 would be great, and some of the muzzle brake/ suppressor options seemed to be removed which was very disappointing. The final area I feel could use some more attention is in the optics/ attachments categories, especially the bipods and red dot area. Its mostly micros and large tube designs where an eotech or aim point would be lovely. Some more trijicon would be nice too. But no other game comes close to the accuracy in disassembly and use of real part options.
