Description
Anyone who has made the switch to a fixed mag solution knows that when you pull your take-down pin the upper receiver will drop and open your action all the way, costing you valuable seconds and possibly pinched fingers during a quick reload. The Cross Armory Flop Stop allows your upper receiver to open enough to drop your mag, but prevents it from opening more than necessary. In other words it keeps your receivers open at the perfect distance to drop your mag quickly, close your action, and get shooting again. The Flop Stop works in conjunction with the Cross Armory Pin Pal, which saves unnecessary wear on your receiver from frequent opening and closing. We are offering the Flop Stop in a bundle with the Pin Pal, or, for those who already own a Pin Pal, a standalone Flop Stop which easily attaches to your Pin Pal. The Flop Stop must be installed in a Pin Pal. Pair the Flop Stop with the Cross Armory Safe Mag and Quick Pins, and you will have the fastest fixed mag reload possible. However, Flop Stop is compatible with most other fixed mag solutions as well, such as the ARMaglock and Patriot Mag Release.
The Flop Stop is made from 4140 Ordnance Steel with melonite hard coat, and fits all AR-15 & M4 rifles.

I’m Having hard time installing the pin pals to my upper but this product allows my upper to open an enough space to release my mag. I love how fast they shipped my order.
Jason G. (store manager) –
Does exactly as advertised. A little pricey for what it is but it does help remove the “flop” and prevents your upper from swinging wide open just for magazine changes.
Michael L. (store manager) –
It is a great product and have it on a number of my setups. That said it does not work well with the BCM KMR rail as this has a smaller profile. It still works but the upper will drop quite a bit before the flop stop catches it.
Joshua A. (store manager) –
This product was a huge pain to install. When I called for support and it’s been 3 weeks and no response.
James H. (store manager) –
It works as described. Fit to the gun is not the best and the screw knurled nut design of the required cross armory front pivot thingy (additional cost – cha ching!) could be ditched for an easier to use ball detent (in the pin) or early colt pivot screw design.

Quality products, a little shaving of the Carbon lower to accept the angle of the Quick Pins but Cross Armory was helpful in sending pics to make this minor adjustment

The flop stop with safe mag /cross pin system is the best Cali compliant system out there . Just works fantastic!!!
