    Great set.

    Swapped my PSA set for this one and was super happy. I read reviews earlier discussing how tight the set was and would verify it’s true. It has a small amount of play, but it has a placement for a tension set screw to remove any movement. Awesome set!

    CM4 5.56 FORGED RECEIVER SET

    Bought this forged receiver set as part of a SDM rifle. Impressed with the fit and quality of this receiver set. Would definitely purchase again and recommend to my friends.

    CM4 Receiver set

    Just got these receiver sets (2) so I haven't had time to assemble them yet. Quality of machining and anodizing is excellent and lower to upper fit is tight with no slop. Order was handled in a timely fashion as an FFL was involved. No complaints with Centurion from me!

    Best Quality for an Unbeatable Price

    You really get more for your money with these receivers. All of mine gauged good with SOTAR gauges. The finish is very nice and matching between the uppers and lowers (for those that place an importance on that), the fit between the upper and lower perfect on my sets (not too loose or too tight), and the uppers are slightly “undersized” at the opening for the barrel for a tight fit. So a torch may be necessary to heat up the upper to get the barrel extension fully seated. It’s amazing at the quality you get for the price you pay. Centurion is truly a top tier brand at a mid tier price. I can’t recommend these receiver sets, or the company, enough. HIGHLY recommend to anyone looking for parts to buy with confidence from Centurion.
