  1. FN PS90
    For people that can only fire semiauto ps90, how is the stock trigger? Is it god awful and only meant for burst or full auto or is it fine. I’ve never shot one, It looks like it will be kind of difficult to shoot semiauto like say like an ar. Also given that bullpups are known for lesser than...

    Finally able to find a PS90 below MSRP! My LGS had one come in and I hopped on it at the price they had! Very happy. Ran some rounds through it and filed the Form 1. Now to find a barrel so I can swap it in once approved. They had some 50 round mags also so I picked up a few.

    Vortex recently released a new magnifier much smaller in size than their original version, which we use for our 3x Optic Flipper. Vortex has ironically named this new magnifier the "Micro". The new micro has an overall length of just 2.9" vs the 4.3" of the original magnifier. The field of view...

    Finally got my stamp back for an EFFEN90 receiver I purchased in October. I did not strip a regular rifle to assemble it, but put it together with parts from MGW and had the take off barrel from my other PS90 (which I replaced with a CMMG) cut down and threaded by Tros. I think it turned out...

    A customer recently sent us their ARD to try to make compatible with one of our MRO mounts. At first we could not find a way to do it. However once we realized we could separate the ARD from the flip cap cover, we found a way. Unfortunately you can't use the flip cover on the ARD, but you can...

Let us know what...

    I am starting to plan out my PS90 SBR build and trying to decide on a suppressor and mount. I have a Gemtech GM-9 and a YHM Phantom LT 7.62 can, and was wondering what everyone's thoughts are on either running a 9mm or .30cal can? I know people have done both. With the GM-9 I could use a...
