Best RetroFit Piston System
MSP has the best price for this kit. All parts look great and fit together perfect. The system works just like its supposed to. The Adams Arms system is a better piston system than many OEM systems out there, maybe less Sig, HK. The only thing is that you will get a little wear on the inside of your receiver, which will stop after break in period, so dont fret. After break in I got my reciever Cerakote finish to protect and reduce friction. Also purchased "roller cam pin" and "anti-tilt buffer tube" from POF-USA. Now its bullet proof.
These must be the best piston systems available.They are extremely simple to install if you have even a minor understanding of mechanics. MPS are also wonderful to deal with and are always eager to help. I would suggest using them for any and all purchases and will myself. I've seen some reviews of mps that suggest they don't tell everything or hold back product for other vendors ,to dispel this I would like to say they must be confused. When I called the fine lady actually left her desk and searched the wharehouse, even transferred my call to a technician to make sure they were going to send me the right part. To top it off she even took my order right then and sent it out, by the end of the day it was in the mail. Nothing but good folks at MPS. Thanks guys keep it up
adams arms conversion
The product arrived promptly, and i had no trouble placing the conversion on my rifle. In all it took about 15 minutes to install , however i had all the tools on hand to do this.
Bought my kit from brownells which was instock and is on transit as we speak! At lease they came through!...I have yet to review my order but from all the ratings and reviews I read this was by far the best conversion kit in the market so that made my decision easy!... Can't wait to install my kit so I can test it out and give another review! Oh and for msp, if you say out of stock, mean it don't be selling on another site (amazon) and say you have only 3 kits left! And make your other customers hang on your own site! When I ordered a k our site, it did not state if you had any or were out of stock! So I did order from msp 1st but only got charged for it and you emailed me saying you were expecting to receive more kits after 2weeks due to out of stock! So I waited, 2 weeks past I contacted msp again, now they say that it.s been pushed back to 2 1/2 months due to high orders! I couldn't wait that long so I canceled my order! Then I went to amazon looking around only to find that you were selling some kits you had available! That really irritated me w hen I saw msp's listing on amazon trying to sell some kits that you said you were out of stock!...... Don't be lying to your customers in the sake of trying to make more $$$ elsewhere! That's bad business if you ask me! But that's only my situation on what happened to me so buyers beware on companies that don't keep their end of the deal!................
