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.

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.

For Builders

For someone who enjoys messing with different set ups and equipment but doesnt have an unlimited supply of money, this is incredible. Yah sure there may be a few hiccups and of course this library of parts isnt exhaustive, but its more then enough to figure out what I wanna spend my hard earned money on. Brownells and the devs of this are geniuses for creating it, will definitely be using them a lot more to buy gear because you can tell they care about the market and they want to inform and educate their shoppers. I love the fact it gives you information about the product, allows you to check down the sights to see if anything would interfere with your line and allows the Animations to move or operate some of the adjustments of the gun, like extending bipod legs or stocks or flip up sight to see how they fit and the placement. Also love the fact it gives you rough calculations on price, length, and weight of your configuration. Its definitely helping builders.
