Looking for a new sight for one of my 16" AR's Either the 556 or the nice compact MRDS. Does anyone have either of them? Might I be able to try?
Has anyone put the MRDS on a slide mount for a pistol? Would it be to big? Can it handle the recoil? Anyone?? |

The MRDS is plastic. I hope this answers MOST of the questions.
I was unhappy about it's performance per it's price. I have been using 4 moa JP JPoints for years (2005 staring in Iraq) at half the cost. I would not put any of these on handguns. I look at it as something else to break. As for comparison to Docter metal sights..."The entire electronics package of the JPoint® is in an epoxy sealed chip with no exposed wiring. This results in improved recoil tolerance and water resistance. The JPoint® will tolerate submersion in water with no damage. The battery may short out momentarily, but it will not be damaged. The Docter has exposed wires and is therefore much more sensitive to water intrusion.- JPoint" If you put a HIViz front, ghost ring rear or both on your handgun and practice with it, I am sure it will pay huge dividends over something fragile (Reflex dot electronic type) in comparison. IMHO, on a rifle as a 2ndary 45 offset yes, nothing else. 
ACOG with a RED chevron will give you a bombproof magnified scope (4X is all you need with the 5.56) and a red chevron for close quick shooting (CQB red dot type work). You'll never buy another sight, nor replace or repair it. V OUT |

I have experimented with this concept using a G-17L
I installed a Leupold DeltaPoint optic with the supplied dovetail mount. Good news. Spooky accurate. I liked the dot size, the lightweight and the fact I didn't need to have the slide milled. Bad news. The Deltapoint was very fragile. One of the TINY torx adjustment screws stripped immediately despite my scrupulous following of Leupolds directions. I sent the sight in for repairs and they turned it around quickly. The next issue was battery life. The Red LED is activated by any small motion. Any slight disturbance switched the sight on. The battery died very quickly, within a week. Replacing the battery requires removing the sight and re-zeroing. See the tiny torx screws. In the end I couldn't trust the sight to illuminate when called on. I was very afraid the adjustment screws would strip and I would be stuck. I returned the sight. With a Trijicon RMR milled into the slide I think the results would have been quite different. I am now saving my pennies for that project. Jeff |

I am familiar with what was called the "doc optic" witch was affordable and durable before Trijicon got it's hands on it and jacked the price up. I thought about the 556 for the AR, but really want a ACOG, but they cost a small fortune. |
I bought one of the 1st of the mini red dots and put it on hunting handgun. Bad idea. Sight was a Tasco Optima 2000. Uses same exact mounting bases as does the JP and Doctor sights, so size is identical. Don't know about function though. The Optima 2000 had automatic brightening capabilities, and there was no on/off switch. It had a hood to cover it, and put it in "sleep" mode when on it. I installed it on a Ruger Blachawk in .45 Colt. I used it for deer hunting, with heavy handloads. 
1st issue.. in the tree stand opening day. 30 minutes before sunrise on an overcast day, I take the hood off. Nothing. No red dot. It wasn't bright enough outside to activate it. It began to glow faintly about 10 minutes before sunrise. Luckily no deer came along in that 20 mins. NOT a night sight by any stretch. Might've been OK on a 9mm used for target or competion in bright daylight, so maybe my use wasn't intended. It was accurate... when it worked. 2nd issue. It took less than 1 box of shells (heavy 300gr handloads) for the recoil to destroy it. |
