Safely build your firearm with this Lantac Advanced Receiver Multi-Caliber to ensure smooth operation with every shot. Lantac machined these Rifle Parts from a billet 7075-T6 aluminum billet and then hard anodized them for complete ruggedness without the heavy weight. The Lantac Smoothcam Receiver Multi-Caliber is a precision-machined upper that uses their patented SMOOTHCAMTM system to greatly reduce friction and create ultra smooth operation. This upper receiver has a burnished bore that eliminates the majority of overall roughness whereas standard bored or milled uppers have an average roughness of 32-63microns/cubic inches. When used in conjunction with the CP-R360TM low friction cam pin, you’ll notice decreased wear on the bolt carrier due to reduced friction against its internal surface. Also, the barrel nut, bore, and barrel fixing assembly are all machined in one operation so that they are perfectly concentric and perpendicular to the barrel and fixing assembly. Install the Lantac ARCA Advance Receiver Multi-Caliber to upgrade your rifle build with one of the best in the business.

I couldn't be more pleased with it! Building a Lantac Raven upper and the fact I didn't have to wait 4 months on back order from lantac and optics planet had them in stock was a huge plus!

Anxiously waited 10 business days to receive my order… When I opened the package I immediately was disappointed because the annodized finish had a purple hazy tint.. This item description states that it is deep black, not purple.. I also have the Lantac Spada hand guard to compare the color contrast to and it's not even close…the upper receiver also had milling marks and blemished milling around the bolt release.. I mmediately returned the item postage free and waited another 10 days for the return verification… now I'm waiting for Optic planet to send me another UNBLEMISHED upper receiver. Side note:….The inside milling seemed to be as smooth as advertised, but not as smooth as my Vltor upper.. Im thinking Lantac is selling their blems to other online dealers… which is fine, but at least it should be stated so in the item description.. I will update as soon as I get the my upper in hand�

Amazingly smooth upper! Very clean! It works very well with my Anderson lower, and my article II lower. Very easy to clean and disassemble. And very good fitment with the barrel. I have since returned to Opticsplanet and purchased a lantac lower

Had to file both the top lip of the ejection port and the forward assist. Tried multiple mil spec and aftermarket parts. Detent for ejection port couldn't articulate until after I used a round file. Ended up using a fcd epc. The forward assist took more work. Teo different mil spec forward assist, two different roll pins. Both would bind to the point they werent functional. If i had the 3/32 punch through in place of the roll pin it would work just find. Had to file down the yhe retaining face of the forward assist unil it wouldn't bind any more. Seems like the hole for the roll pin was drilled too close in to the center of the forward assist. Overall it looks good, but I wouldn't recommend this. Both the vltor billter upper and silencer co billet upper are better options.
