Hey guys,
I just acquired my first 50  I got a Barrett model 99 from a member here in the equipment exchange at a great price.
I'll be putting a Super Sniper 10X fixed scope on it that I'll be getting from SWFA. Can any of you super knowledgeable guys please give me some recommendations for a good strong set of scope rings and also the optimum/correct height rings to purchase. Thanks in advance |
I picked up a set of Badger Ordnance rings for my old Bohica upper... (full length top rail). I needed the ultra-high rings (1.450") to fit my 6-24x50 Nikon. I took some measurements to be sure I got the right rings. At $200+/set... I couldn't afford to just toss them in my toolbox if they were wrong. 
I got them from BROWNELLS You want the "MAX-50" rings. 
These are the heights available: Max-50 - .823" (2cm) Max-50 High - 1.125" (2.8cm) Max-50 Ultra-High - 1-29/64" (3.7cm) Ring height measured from top of mount to center of ring. Depending on your tube size, you may also need the MAX-50 sleeves to reduce the 30mm rings to 1".

I am actually wondering the same thing, although on an AR50. I am planning to mount a SS10X42 on it and so far, I’m leaning toward TPS Tactical steel rings for durability and affordability. Badger Ordnance rings seem to be favorer among BMG shooters, although I’ve seen Leopold Tactical (aluminum), Burris Tactical (aluminum), and TPS rings used as well. I imagine that there are a number of different brands/types that would be sufficient but I still am willing to sacrifice weight for strength and go with steel rings.
I called SWFA last week and they are out of stock of both the SS10X42 (supposed to be in next week) and the TPS rings (medium/steel) are on backorder with no stocking date insight. So, I may have to look somewhere else. I also inquired about Burris Tactical rings (medium size) they are also on backorder, but the rep told me that they did have SWFA rings in stock (handle BMG recoil?). As far as ring height, the AR15 upper guys like the high/extra high rings to get a proper cheek weld, my AR50 is a whole different animal which I believe your M99 is as well. I prefer to position the scope as low as possible while still maintaining enough clearance for the objective lense and functioning of the bolt (especially on the AR50). Your M99 is a bullpup design and shouldn’t have the bolt problem as long as the bolt handle doesn’t get in the way. From there it is personal preference. P.S. If I hadn’t found a good deal on an AR50, the M99 was at the top of my list, enjoy!

I went with some TPS rings (steel) because the price was right and they are good quality from what I understand, I also went SS but with my upper I have a 20 MOA riser and the SS only has a 42mm bell so I went with low rings. You might go look at SWFA as they have both the BA and TPS rings as well as many others. Also a sponsor. |

i went with the Precision Reflex Inc. steel mega rings with 25 moa built in on my MKII
solid mount, kind of thing you can pass on to your grand kids great if your not worried about the weight (there heavy) and if you have a flat rail and plan on shotting out past 700 yards 25 moa can help

Everyone seems to focus on getting a wide ring for their 50cal when it isnt necessary. What is critical is that the bore and mount surface are parallel. Ive been installing Nightforce rings on our rifles for about 7+ years without any problems. They take minimum lapping. Rings I used before, many of which have been mentioned in this thread, have had isues that show up in lapping.
Even though the NF rings are only 5/8" wide, the scope will not slide in the rings if installed properly. The heaviest recoiling rifle Ive had them on was one of our uppers with a 36" barrel on an AR lower (25 lb) shooting 894gr projectile at 2600 - 2700 fps. Here are a few tips; Make sure the mounting surfaces are clean and oiled. Make sure the screws are clean and oiled. Mount the rings to the rail, then the lapping bar into the scoperings and torque it all down. Remove the lapping bar and lap the rings. You should see a lapping pattern on the rings covering 75% or more of the surface in 1 to 2 minutes. Oil the ring surface, drop the scope in and torque. Use a good inch pound torque wrench. Use a criss cross torquing pattern that ends with the first screw torqued. Torque in stages - 5inlb, 10inlb, 15inlb Repete the final torque sequence until all screws remain at the final torque spec.
