Ergo grip 2 ar15/ar10 - Ergo 2 AR15/AR10 Ambidextrous SureGrips Kits

I recently purchased one of these grips for installation on an early '90's Armalite AR 10. I had been searching for an acceptable substitute for the supplied A2 grip for quite a long time. I had bought one of Ergo's earlier two piece units some years back, but found it lacking in aesthetics and function in terms of access to the trigger for my short fingers.

I was surfing the web when I discovered that Ergo had developed this newer one piece model, advertised to fit both AR 10s and AR 15s. I am usually suspicious of anything that purportedly is a one size, fits all solution. But, because I was well satisfied with the standard Ergo for the AR 15, I thought I would give this product a try.

I wasn't disappointed this time around. It was about a 5 minute replacement. This grip follows the general form of the AR 15 model, and requires no extra part to make it fit the Armalite lower.

I did discover one minor problem though. I noticed immediately that the pressure to operate the safely was greatly diminished. It hardly required any force to operate it at all. I was concerned about this as it appeared that it could be accidentally moved to the fire position simply by friction from clothing or being carried through the brush. I suspected that the hole housing the spring for the safety detent was manufactured to a greater depth than on the original A2 grip. I measured them both with my calipers and discovered that indeed, the hole in the Ergo was about .10" deeper than that in the A2 grip. What to do? I looked through the odds and ends I have laying around and found a piece of plastic rod that would fit in the hole. I then cut a .10" spacer out of it, dropped it in the Ergo grip, reassemble it to the rifle, and checked the function of the rifle. Problem solved.

I mention this only because of the hazard with the light pressure on the safety. It doesn't diminish the appeal of the product. With the variety of different .308 ARs available today there could be some variation in how deep the lowers may be drilled for the safety detent and spring. This may, or may not, be only a peculiar issue with the Armalite. The dimension is different for the two grips. This is just a heads up to those who purchase one of these; always check your rifle's function when installing new parts, even one so mundane as a pistol grip.

All of that being said, I think the grip is a good product, and I am happy to bid the A2 grip farewell.
