It looks like there are more and more bullpup stock kits entering the market all the time, well here’s one from Bullpup Unlimited I just stumbled upon for the popular Remington 870 shotgun. As with any typical bullpup kit, the overall lenght of the firearm is shortened with no loss of barrel lenght as the 870 action sits further back. The kit does add a little under a pound of weight to your shotgun but the weight is transfered further back, so I’d assume it would actually improve the balance of the shotgun. The Bullpup Unlimited kit uses an AR-style pistol grip and has plenty of rail space for grips, lights or lasers. At $359 it’s almost the cost of an actual 870, but if you’ve always wanted a bull pup shotgun then this might be a sweet project to play with.
