Which BCG and charging handle for my PSA 300BO upper? Don’t need super tacticool just basic solid parts. Too many choices. Any help breaking it down? Thanks in advance.

Are the MOE Dissipator uppers still in production?

How do I report a damaged part in my AR15 build kit?

I just bought the PSA 16ā€ mid length 5.56. It came with a really inferior owners manual. Picture inside the manual isn’t even the same gun. I need to know how to take it apart, proper users manual , etc. Is there a better manual that really explains EVERYTHING about the gun ? It doesn’t even tell me how to install the front and rear sights ….any help out there ?

A link to the exact rifle / pistol that you bought would help us help you.

Anyone know when the PSA 16" MID-LENGTH 5.56 NATO 1/7 NITRIDE 13.5" LIGHTWEIGHT M-LOK MOE EPT RIFLE W/MBUS SIGHT SET, FDE will be back in stock? it was in stock then I went to get my credit card and it went out of stock 2 min later, need this rifle bad, if its going to take over 2 months then I’ll just find another one. let me know thanks!

Ordered the basic PSA starter LPK.
I don’t see any markings on the hammer or trigger. Are the forged or MIM?

You could buy the complete upper, and the complete lower separately. Might even save money that way. I bought two EPT MOE PSA lowers, one PSA MOE 16" midlength gas upper and the other Aero Precision (because PSA didn’t have a 20" MOE upper in stock).

P.S. All PSA lowers free shipping this week.

I am trying to custom order a PSA CUSTOM 5.56 NATO 16" NITRIDE 15" MLOK RIFLE W/ 3.5LB CURVED BOW FCG with a custom paint job but can not find out how to order it, I need help

Hi,
Looking to build a 300blackout using my Colt M4 - LE6920 lower.

Will the PSA upper PSA 7.5" 300AAC BLACKOUT 1/7 NITRIDE 9" LIGHTWEIGHT M-LOK UPPER WITH BCG & CH mate with it?

Thanks,
jt

anyone know the difference between sku 5165451017 (tab says psa ar 10 upper in 224 valkyrie) but in the detaiks it says: The 224 Valkyrie upper is designed to function with any Mil-Spec AR-15 Lower Receiver and is to be used with a standard 6.8 SPC Magazine.*** . Sku 5165450176 is 224 valk. also, tab just says psa 20", product details and features are the same for both

Can anyone tell me what the differences are between these two? 516446780 vs 5165447638

I’m having the same problem, spoke with CS and they inquired with a product specialist who claims there is no difference.

Just relocated to Ca and never put an upper and lower together and wondering if the psa 10.5 1/7 nitride upper with bcg and ch is compatible with the Psa ar15 complete lower moe ept stealth lower and if I can have them both shipped to my home in ca.

Can I find a date of manufacture on my AR15 with a serial number? It’s 4783. Thank you
