Re: Rear Sight

Any standard-height rear sight will work so long as you have the "tall" front sight post- these now ship standard and came with my upper from Atlantic last year so yours should have one. You will need to crank the front sight up quite a bit in order for it to correctly sight in. The front sight post...

Re: New to Forum and T91 - I have 2 T91 Questions

Isn't this the same issue on standard ARs with A2 stocks? All AR models and derivatives suffer from some carrier tilt irregardless of carriers or buffer tubes. This is due to a combination of the geometry of the carrier and the gas acting on the gas key as it's funneled into the piston chamber allo...

Re: New to Forum and T91 - I have 2 T91 Questions

I would not recommend using a rifle-length buffer tube on a T91 without using an anti-tilt buffer. The rifle buffer tubes do not have any countermeasures for carrier tilt, and you may end up wearing out your tube prematurely. On top of this, no one makes a rifle-length anti-tilt buffer tube, and POF...

Re: Q for those of you who build a mil-spec FSB T91 with .750 journal 14.5/16 barrel

By the way, did you have to drill another gas port for your 14.5 wolf a1 barrel after the mil-spec FSB is installed? Nope. Luckily the gas block I ordered had the port already drilled out, and it lined up perfectly with the existing hole on the Wolf barrel. On the Anderson barrel, did you block off...

Re: Q for those of you who build a mil-spec FSB T91 with .750 journal 14.5/16 barrel

I originally planned to do this as well and did more research than I thought was necessary, but it wasn't enough. So, the gas port on the T91 IS in the same spot as on a standard mid-length AR gas system, but it is drilled at a 30 degree angle like an AK. Whether this will correctly line up with a p...
