| I have a Colt HBAR flat top issued to me at work. 20" barrel with the carry handle. What would be a good, reasonably priced mount to use for my EOTech or a scope? |

Be sure to consider eye relief as well as height - the Picatinny rail on a flat-top may not let you mount the scope far enough forward for a comfortable position, especially in prone. I use an extended riser (1/2" high) made by Accuracy Speaks (available direct or from Brownell's) combined with standard-height rings. There are now a similar ones available from Compass Lake and White Oak, among others. This gives me an extra 4" of rail to let me mount a Leupold 6.5-20x50 LRT (a rather long scope), and gives me the option for an extra 15' of built-in elevation for long range work. For ranges up to 600 yards, a simple rail extender like YHM's <http://www.yhm.net/store/rails.html> should do the job for less money. I'm using Burris Signature Zee rings - they are inexpensive and work well, even though they don't have the macho look many seem to like. They use a floating plastic bushing to minimize stress on the scope tube and simplify installation, and offset bushings are available. Bushings with a 0.010" offset are included with 30 mm rings, and 0.010", 0.020" and 0.030" bushings can be purchased for 1" rings. They're inexpensive and work very well. I use them on my spacegun to mount a VX-III 6.5-20x50 LRT and have never had a problem with them. Removing and replacing the scope has never shifted the POI. Also remember that your windage range is restricted when you are at maximum or minimum internal elevation. You can't apply maximum elevation and windage simultaneously due to the round scope tube. You won't need large amounts of windage at 100 yards, but you could need 20+ minutes at 1000 on a windy day. There are minor optical distortions that may be more apparent off center, but the biggest reason to stay on center at long range is to have adequate windage adjustment available. |
| Thanks, that's a lot of good info. In law enforcement it is doubtful the average shot would be made at more than 50 yards. However, I work in a rural/desert area in So Cal and it's conceivable I might have to take a shot at 200-300 yards. That's why the 1/2" riser sounds about right. I doubt I would shoot so far as to need built in elevation. |
