Is this barrel chrome lined? Is see the steel type but no reference to the lining.
Tffrost on May 28, 2018
BEST ANSWER: Remember these are made from chrome moly vanadium steel. they ARE chrome, just not extra chrome lined. Clean yours up and look down it with a bore scope and it will blind you. I think they are better than nitride diped. I can hit a can of pork and beans( a small can ) at 200 yds with a carry handle sight.

Will. This upper fit on my carbine lower?
jeff k on Jun 1, 2018
BEST ANSWER: If you put this upper on a carbine lower you can be subject to a fine or jail time or both by the ATFE.As of now you have to have a SBR (short barrel Rifle ) Stamp and ID. What is nice and LEAGLE is you can attache this to a pistol lower or build a lower with a pistol BRACE.
So as long as you build a pistol this would be legal to buy and install? No nfa papers?
Jason W on Jul 4, 2018
BEST ANSWER: Has to be a designated pistol lower, Pistol buffer tube, and if using one an ATF approved pistol brace like a Kak Blade. but it is up to you to check your state and local laws
Can the front sight assembly be easily removed?
JimKy on Dec 20, 2018
BEST ANSWER: Easily is a relative term but it's an A2 gas block/front sight so you'd have to remove the whole gas block as well as the A2 birdcage in order to slide the gas block off the barrel. Then you would need to replace the gas block with (presumably) a low profile one. Honestly it's probably easier and cheaper to just buy a different upper that already has a low profile gas block and free floated handguard or buy this one and keep it as is and just cowitness a red dot with the irons. Alternatively you could saw the front sight off and make it into a low profile gas block suppose... But I'd recommend the above options or just look up a video on removing an A2 front sight.
this come compleat with bolt ?
leonard cousino on Jul 15, 2018
BEST ANSWER: No, when you see without BCG this mean no bolt carrier group or charging handle. You need to order those separately.
Can this upper be attached to any “standard” at lower ?
Joeyp on Jul 8, 2018
Can you use a 7.5" pistol lower with this 10.5" upper? Would there be a difference with the gas ( ejection) and buffer/ spring?
Jay K on Jun 8, 2018
BEST ANSWER: Yes you can, if your 7.5 functioned well, it will run even smoother with a 10.5 using the same buffer and spring. The longer gas system in my opinion is superior from the pistol length
can it be shipped to my front door?
gunner on Aug 21, 2019

Since this is not a firearm, you can have it shipped to your residence.

Just SBR'd...
So once again I purchased another one of these for my most recent SBR build and I have no complaints. It shot my .223 reloads without a hitch and it looks freaking sexy with the XM-177 hybrid muzzle device, A2 carry handle and slim hand guards. Plus I gave it an OD green and battle grime finish to top it all off. Looking forward to sending more lead downrange with this SBR. Thanks again Palmetto State Armory.

Great Deal!
Best possible deal for the money, palmetto state always delivers excellent stuff for a great price. This is one of many products I have purchased over the years and does exactly what it’s supposed to. Put numerous rounds of many types of 223/556 from 55-77 grain ammo and not a single hiccup.
