I knew when I first heard some of the bold claims about the Geissele mrgg rifle that I was going to want one to try myself. When they started showing up at Euro and a few other places I went ahead and put an order in. Initial impressions were positive. Fit and finish is unreal. I personally think it’s a super sexy rifle.
Rifle ships in a nice pelican case with gun lock, manual, and a sweet beanie. Which brings up my first complaint. Give me a freaking magazine with my 6k rifle geissele. Yes I have plenty but it should be standard. Yes I understand ban states etc but literally every other company makes it work. Let’s start back to front.
STOCK-Ships with a Magpul prs lite. I honestly thought I would change this out. I like a short lop on my rifles but after shooting with it I believe I’ll keep it. No complaints.
PISTOL GRIP-I like the grip they use on their rifles and it will stay on my rifle. If anything I wish it was a hair more vertical. It fits the hand nice though.
TRIGGER- Comes with a geissele ssa-e trigger which is my favorite offering from geissele. No complaints.
RECEIVERS/CONTROLS- The receivers are machined beautifully. Like work of art beautiful. One complaint I have, and this is carried over with the gfr. They’re to tight. I like a tight upper/lower fit with minimal wobble. What I don’t like is having to use a plastic punch to pop the pins out to field strip. There is a spring loaded plunger in the lower that keeps fitment tight. Maybe a little less powerful spring would split the difference?
The left side ambi controls are great. I have zero complaints there. The right side is growing on me. The right side bolt release is pretty stiff but has seemed to wear in a little and I can now depress it with my index finger. I do on the other hand struggle to reach the dust cover which actuates the catch on the right side without breaking my grip substantially. With that said I have the hands of an 8 year old girl.
HANDGAURD- I love the handgaurd. Super solid and has a tab at the 12:00 that interlocks it to the receiver. Full arca rail with mlok slots on the bottom. Two steel qd cups that are positioned closer to the receiver and an included geissele mlok qd cups.
BCG- The bcg has nice machining and a slick finish. I’m a fan of the nano coating as it cleans up great and has a natural lubricity feeling to it. Bolt has dual ejectors and gas key has good staking. It appears the carrier has some sort of plug/weight? In the rear. Not sure what this is maybe someone will chime in with the answer on that.
CHARGING HANDLE- Comes with a nice Geissele charging handle. No complaints.
BUFFER/SPRING- The Mrgg uses geisseles super 42 braided spring and a h2 buffer.
Geissele advertises the barrel as “user changeable” (isn’t that every ar?) . Here’s the barrel nut pictured. The handguard screws are captured which is nice.
I struggled to get pics of this but the Mrgg has two sets of feed ramps. One in the normal spot that interfaces with the receiver and another set before the chamber. I assume this helps with bullets not getting deformed.
Now for the accuracy portion. All groups were shot from a bench. A bipod and rear bags were used for all shots. Upon getting the rifle I fully cleaned the bore and shot 10 rounds to zero and season the bore. A Schmidt 5-20 ultrashort was used in a badger comm mount. I want to also mention I tend to shoot much better with a suppresor. All these groups were shot with the hux brake.(haven’t decided if I want to order a hux flow or not)

Group 2 the 5th shot was the flyer. Unfortunately it still counts but I will say that shot didn’t feel good. I still included what the group would have measured as a note in the target.

It definitely seemed to like the 140s better. I was also a little fatigued trying to make y’all proud and the rifle was hotter. I noted two groups that I didn’t wait as long to shoot on between 5 rounds. Being a gas gun I wanted to see how it did a little warm.
I REALLY think this rifle has potential. Keep in mind this a chf chrome lined barrel! Geissele has their barrel making down. So far I LOVE THIS GUN. Will definitely pick up a 16 inch and 14.5 when they drop. I plan on shooting more when I get a suppresor mounted up. Will get some more factory match ammo options and post up results. I experienced no malfunctions as one would expect. It has a really nice recoil impulse that seems “slower”. I’d encourage anyone who has one to post your findings and results! If anyone has questions for wants info on something specific just ask!
