What is the difference between this kit and sku ending in 142?
Marvin J on Mar 31, 2019
BEST ANSWER: Based on the pictures, the rail appears to be different, although the description doesn't indicate a difference.
Is the gas block adjustable? (The Magtech subsonic .300 blackout ammo sold by PSA suggests this is recommended)
Berwick L on Apr 25, 2019
BEST ANSWER: It’s not adjustable out of the box, but mine has been 100% reliable with subs (suppressed, because why would you shoot subs otherwise?) I’m running the buffer and spring provided in this kit.
How long would it actually take to receive this if I ordered it? Last time I ordered something, it took weeks.

What is the weight of this kit, either with or without Lower Receiver?

Great build with law tactical G3 folder
Haven't fired yet, need to buy some 300 aac, but built on a PSA spacerider lower, bought when it was a daily deal and ordered the law tactical adapter for sale on Brownells, so 320$ upper and build kit shipped 69$ lower shipped and 204$ shipped law tactical g3 adapter and for 600$ I've got a great looking truck gun that's 20" long folded and I do t know if it was a mess up on PSA's part but my bolt was black nitrided not phosphate coated, I recommended to everyone I knew before it was sold out, if you missed out you should be upset about this one.

Great price for a .300 pistol kit
Went together easily as expected from PSA. Paired with FDE lower, grip, and mags for a two-tone black and tan finish.
