can you install a carbine length quad rail to the psa marauder?
cesar on Apr 21, 2018
BEST ANSWER: Yes you can. I have a drop-in 2 piece carbine length quad rail on mine.
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
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 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
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.
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.
Is the muzzle device pinned?
Dave L on May 16, 2018
BEST ANSWER: NO it's not pinned, it's threaded.
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.
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: Maybe, but make sure to check for how the hand guard attaches. if the new hand guard has its own barrel nut, you’ll need to uninstall the nut on this one, and install the proprietary one. The muzzle shroud on this is a direct attach to the barrel by 1/2x28 threads.
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.
What size buffer weight are y'all running?
DANIEL H on Jun 7, 2018
Can this be shipped to New York State?

Make the smallest badass 5.56 ever
I purchased this and built the pistol of my dreams! Its acurate and unbelievable but true! 50 yards all shots (from rest thats true) were right in the ten ring. I put on a SBA adjustable pistol brace? wierd but its legal, I added the LAWS folder. a put on a vortex spitfire 1x prism with two rings and a 1moa dot , if you need light it can be turned on green or red. I never bother. I change the front wnd to a Mag Pul SL which is longer and covers everything up front. its so small wven with my D60 drum that I can put it right into my pack. oh! i forgot I put a Binary trigger on it! holy cow when Ol Hillary finds out she'll [...]

Great quality upper.
This thing is so much fun to shoot! Fit and finish are great, shipping was fast, and snapped right on to my Polymer 80 lower with no fuss. Shoots great, and has the added benefit of looking like an old musket. You have to have one of these in your collection.

Great deal. Shoots great for a 7 inch barrel. No issues at all. Just bumped up the buffer weight to an H2 to slow it down a bit
