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!
Well made set.
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.
Absolutely fantastic product and even better people standing behind this company.
The quality of these sets is next to none. Some of the coolest people in the game. If your on edge about buying take my word for it its well well worth it.
Thanks guys!
Absolutely gorgeous ano. Tolerances that are as tight as you'd ever want. On top of an amazing company run by genuinely great people. You can't go wrong with centurion. I would and have purchased again.
