This has been my 2nd geissele mk4 rail. My first mk4 was actually the 9.5" and more recent is the 9.3". You cant go wrong using the MK4 system!!! Durable, reliable and solid!! The ris ii Quadrail cant compare IMHO.

This is a no nonsense quality built rail!!! I would reccomend this for any pistol/sbr build !! The machining fit and finish is just top notch!! Has all the rail space you need for anything you want mounted and gives your firearm a serious business look!!

This rail has the most complex and smooth machining I've seen. It's far beyond anything I've had (BCM, Noveske NSR, DD, etc.).Light and VERY strong, Geissele is my go to for rails now (Radian is my go to for CH now).

I have purchased geissele products for the past 7 years and have always been happy with them. Ordered this hand guard with same expectations of quality that i have come to expect from geissele in the past. Upon inspecting the hand guard i noticed some really rough machining marks near the mounting area. I thought that it may just be how they manufacture the rail but doing some research online, from looking at friend's geissele rails, and noticing the the machining marks are not uniform came to rhe conclusion it isnt how the area is supposed to be. There is no doubt this is a great and durable product from a reputable company but the quality control on this particular item was over looked. I believe if i am spending $250 on a product that the quality of craftsmanship and finish should be high. I would recommend this product but not this specific rail for the maine reason i stated.

It's great, wish I had the QD steel reinforcements that come with the newer ones but I can live with out it. Solid construction and build and no surprise from Geissele. Installation was a breeze but kind of meh about having to buy a proprietary nut wrench separately for it. The set screws that provides another way of preventing the handguard from rotating is a little bit antiquated an will mark/mar the lower receiver. I would give it 5 stars if they would just change that to tabs that interface with the sides of the lower and include the wrench for installation.

Nice handguard if you can get OpticsPlanet to send all of the parts with it. You can buy this directly from Geissele for the same price. When I received mine it didn’t ship with the barrel nut or screws.
