can you install a carbine length quad rail to the psa marauder?
cesar on Apr 21, 2018
BEST ANSWER: The good thing about this rail is that you can use the magpul moe rails to this item for sights, lights, laser, whatever you want attached to your weapon. This works the same way without the cheese grater feel. I have this exact same upper and enjoy it. I hope this is helpful.
ETA on when this will be back in stock?
Gunnar D on Sep 26, 2018
BEST ANSWER: Right now. I just bought one.
When will they be back in Stock?
George U on Feb 7, 2019
Can you remove the flash hider and install a different one?
Bryce H on May 8, 2018
BEST ANSWER: Nope. You would have to change the handguard to a free float system.
What is the overall length?
How long is the flashcan?
Rhino on May 9, 2018
BEST ANSWER: If you install on lower with a KAK Shockwave brace it measures 24 inches
What am I going to need to complete the upper?
Cody P on Aug 19, 2018
BEST ANSWER: You will need a bolt carrier group and charging handle. Also what ever optic you want to run on there. I opted to do the psa bcg and charging handle and have been pleased with its performance
Not having BGC does it need
To be sent through a FFL to receive it?
William R on Aug 30, 2018
BEST ANSWER: This is an upper receiver. Upper receivers never need to go through an FFL regardless of whether or not they come with BCG. Only lower receivers need to go through an FFL since they are the part with the serial number.
What type of grouping are you seeing out of this upper?
Ryan J on Jun 11, 2018
BEST ANSWER: That was my question as well before I purchased it. I was very surprised. It performs very well. I sighted it in at 50 yards. I have not fired it farther yet. However, at 50 yards my group was a half dollar size groups if properly stabilized and fired with strict trigger control and sight alignment. I recommend.
Can you swap out that moe handguard to magpuls new SL handguard or would strike industries 2 piece handguard fit there?
Daniel K on May 19, 2018
BEST ANSWER: most hand guards are interchangeable, though some may require their own barrel nut to proper fit
Does this muzzle device throw a fireball, or does it hide the flash?
RangeToys on Aug 11, 2018
BEST ANSWER: The muzzle device this item ships with is set up to hold the hand guards on as well. To answer your question, yes it throws major fireballs. It’s a good range toy or my use for it is a SBR to keep in my dozer where I work for eradication of varmits and predators. It functions flawless and looks neat.
Can you put a suppressor on It?
Phil J on Nov 27, 2018
BEST ANSWER: You can't with that muzzle device, It's made to hold the handguard on and isn't threaded. You would have to get a different handguard that is free floated and remove that muzzle device. You would probably be better off buying a different upper if you want to use a suppressor
How long does this take to recieve?
Lowlife on Dec 7, 2018
BEST ANSWER: I'm sure this is mostly influenced by your location in the country. I live in the western US and it took 10 business days for it to arrive, however it has been worth every day and every penny! Super fun addition to my collection!
does this have the normal 1/2 x 28 threads on the muzzle?
Collin F on Dec 3, 2018
BEST ANSWER: Yes, you can swap it out with any other 5.56 muzzle device.
Is the muzzle device pinned?
Dave L on May 16, 2018
BEST ANSWER: NO it's not pinned, it's threaded.
Do they make the marauder in 9mm?
John C on Sep 26, 2018
BEST ANSWER: I don't think so. Go on the PSA site and look under AR 9, you may find an upper like it.
Can you make the handguard in olive drab green?
Gooseman on May 7, 2018
BEST ANSWER: Usually the special Palmetto offers is the exact one that is showed on the email you received.
Different colored handguard most likely will be different price but to be sure you would have to call Palmetto customer service on the Olive Drab colored handguard price.
Would an Adarms Arms xlp piston pistol
kit fit under the hand guard ?
J E on Nov 30, 2018
BEST ANSWER: If the piston plug is same size as gas trap on pistol upper. The gas piston issue would be the width not length.
Own this upper and is paired with a BCM lower AR pistol receiver with BCM BCG and Radian charging handle. Used H, H2, and H3 weights with 3 different springs and 2 different types of ammo and cannot get it to cycle. Any recommendations ?
Doug S on Oct 14, 2018
BEST ANSWER: if it won't cycle with an H buffer than it's more than likely the gas system. I would check the gas block to barrel interface, it may be twisted and not allowing enough gas thru the gas tube.
Do you make a 300 blkout version?
dangloc89 d on Sep 3, 2018
BEST ANSWER: I don’t believe they make the maurader in 300 blk. It’s a pretty fun pistol in 5.56 though.
what buffer weight are you guys running in this upper?
Daniel h on Jun 8, 2018
BEST ANSWER: I use a H2 buffer. It is heavier and slows down the bcg. Also helps with some of the recoil. The buffer had two steel weights in it. Makes it a lot heavier than the standard carbine buffer.
Any chance this exact configuration will ever be available in .300 AAC Blkout?
Tyler on Feb 2, 2019
What size buffer weight are y'all running?
DANIEL H on Jun 7, 2018
Can this be shipped to New York State?

Great Pistol Upper
I paired the Marauder Upper with a complete PSA PA-15 Multi Cal SBA3 lower. I am running a Brownel's Nitride BCG. The pistol runs flawlessly on any kind of ammo. I mounted a Bushnell red dot on it and it is plenty accurate to hit plates even out to 100 yards. This is my second PSA upper and I think they are a great value and good products for the money.

Great upper. Great AR pistol
Had a great time completing this build with my son. Put it on an Anderson lower and added a hologram sight. We used a BCG I had laying around. Fires great.

Palmetto wins again
Very happy once again with PSA. Wanted a first AR pistol and decided on the Shockwave lower then added this. The hardest part was catching it in stock. First range trip was trouble free and also worked great with my .22lr drop in conversion. Great product and service once again.
