I purchased the gas piston system. Have not used it yet but want to give 5 stars for their customer service. I am sure the gas piston will also rate 5 stars.

Great experience.

I've used several of your conversion kit on carbine's for my self & family members. I also have several rifles of yours I am very happy with all of your products that I have bought & used

I've bought 2 piston kits so far at separate times. Received both in timely fashion and no problems. Will use on any future builds.

Always a pleasure doing business with Adams arms

I wanted to upgrade my AA-15 with the newer M-loc handguard, bringing my rifle up to speed and more versatile and to float the barrel. The customer service assisted with getting the correct parts and the rifle looks great and functions flawlessly. Great customer service and speedy shipping.

I love your piston system , although your inline instructions need to be updated , I got the no bushing note , but a washer came with my micro adjustable , that if it wasn’t intended as a spacer for piston rod it is now ( for thermal expansion per the online instructions ) and I have one gun that has your adjustable micro drilled and pinned , but you “ don’t recommend “ doing so , is there a specific reason ? And my kit came with a bent rod , I never could get it to not bind if it rolled , would work fine with the port up , but not rolled down , vice versa ,I sent a email , hoping it would be a warranty replacement situation , I never heard back , and have since bought a new one and all works perfectly , yes I did try the bent rod , it would cycle far enough back to pick up another round or lock back on an empty , it would bind it very last of the stroke , after not hearing from you I tried to straighten it ,,, didn’t work . But again love your piston setup , currently running three , suppressed no issues . Kevin

Most recent is the 4th AA kit I've purchased over the past 11 years and shipped fast. Quality, fit, function, and price point are great for these products. I especially like piston over di because they don't sh*t where they eat. Much cleaner and overall easier to disassemble and clean.Would be nice if AA offered 3/4" ID peel washers for establishing an easier method of gapping the gas block/op rod, but certainly not a deal breaker for me. I've used the peel washers I found elsewhere successfully for gapping. Great stuff from AA, keep it up!

Outstanding customer service! prices are excellent and most importantly, top notch products!

The Adam’s Arms rifles are excellent in quality and performance. Their short stroke piston set up is all I shoot now.

Nice experience except some parts did not arrive, that was corrected later. They went out of town for a while and were incommunicado. It was frustrating because they did not say that they were going out of town on the voicemail and I thought they just weren’t returning my emails and calls. Their tech-support was very helpful.

Piston kits are a great product, no drama. Fast shipping, no surprises.

Your customer service is excellent.
