Rifle Scopes GA PRECISION GAP-10 SPUHR Scope Mount Question

[Millionaire]

Hello,

I am going to purchase a SPUHR scope mount for my GA PRECISION GAP-10 and VORTEX RAZOR HD GEN II 4.5-27x56 riflescope.

I know I want the 6 MIL/20,6 MOA cant built into the scope mount.

I'm wondering if I should get the cantilever or non-cantilever version?

Spuhr - SP-4616 Scope Mount 34 mm (Cantilever) Picatinny

Spuhr - SP-4602 Scope Mount 34 mm Picatinny

Thank you in advance for your help and input.

Cantilever if you don't have a rail on your handguard or cantilever either way.

Something else to consider-- with the raised scope rail integrated into the handguard on the GAP10 the scopes sits higher than on a "normal" DPMS or AR10... I used a standard 1.18" height 20MOA Spuhr mount for an S&B 5-25 on my GAP10 and even then the cheekrest on the PRS stock was nearly maxed out on up adjustment to get my eye lined up with the scope. The cap on the objective bell barely cleared the relief area in the handguard.

With a 1.46 tall cantilever Spuhr on a GAP10 there's no way I would have been able to get the cheekrest high enough to get into the scope without adding padding or something similar to it.

You probably don't need a cantilever on the GAP10 as unlike a standard DPMS or AR10 the GAP10 rail continues well forward of where the upper receiver stops so there's plenty of room to scoot the scope mount forward. My S&B 5-25 was just fine in terms of forward/back fitment even with a standard Spuhr and the S&B 5-25 is a pretty long scope.

However, a 56mm objective is a very tight fit to the handguard relief on a GAP10 with a standard 1.18" high Spuhr-- your Razor Gen II may or may not fit. Personally I'd look for a mount that's about 1.25-1.30 tall-- unfortunately Spuhr doesn't make a 20MOA mount in that height. Spuhr does make a couple 1.35" height mounts but they're 0 MOA only for now.

IMO, the 20MOA 34mm/30mm 1.27" tall Badger mount included with the GAP10 is just about perfect.

Thank you for your input.

I did not realize the scope sits higher on the GAP-10 compared to other AR-10 platforms.

I will try the 1.18" height instead of the 1.46" height.

I will use the Badger Ordnance mount that comes with the rifle in the worse case scenario but I really like SPUHR mounts above all after installing/using the SPUHR separate rings on my bolt action rifle.

If you really like the Spuhr mounts, no worries. They offer 1.34" in height. You can sell your BO mount, and put that towards the Spuhr, I would

Check the eye relief before you roll with a cantilever mount. You might find yourself ridding off the cheek weld.

I like the badger that came with my Gap-10, I don't see any reason to spend more money on a Spuhr. I have a S&B pm11 5-25 on mine it fits perfect.
