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.
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.
Is the muzzle device pinned?

Blast effect.
One of the most efficient operations of this upper is the deflection of gasses and blast effect away from the shooter and others nearby. Very effective in diverting both noise and effect away from others nearby.

One of my favorites.
I have this paired with an Aero lower and KAK blade, no functionality issues ever. This is one of my favorite builds and I would definitely buy it again.

Excellent Upper.
Great upper. Quality was top knotch. I coupled it with an “I Stand” lower and KAK Brace. Fit is tight and there is no rattle.

Not a bad choice for a pistol upper. Needs a little extra cleaning due to unburned powder but worth the effort. Make sure you wear your hearing protection. VERY LOUD

So impressed with this little upper. Shoots everything I put through it. I’ve shot it out to 450 yards( just for fun) and hit steel. Every time I take it out it puts a smile on my face.
