My First MWS; Classic Army's AR-15 URGI 13.5"
Hello! I've recently moved on from VFC's UMP9 due to the spare parts not being available in my country in addition to the hassle of ordering them overseas thanks to the bad customs. Since I don't want to return to AEG, I figure I might as well buy an MWS. This Classic Army model is 300$ (not including the attachments of course) which seems to be the cheapest MWS in the market I believe? It comes with 2 picatinny rails adaptors for M-Lok out of the box, which is amazing.
My first impression with this thing is, it's much better than any of the Golden Eagle models I've seen, even with the 2026 batch (which is a low bar imo), stable system, mag feels very lightweight for me, crisp bolt noise, stable full auto. But I find the trigger to be very weak and terrible, as well as the replica being super front heavy. The stock grip also feels like crap, it hurts my middle finger from just holding for a while. Definitely needs some time to get used to it. 💀
I'm not new to GBBRs in general, but I am to the MWS platform. From what I've heard, this MWS is basically a 1:1 clone to the original Tokyo Marui's, meaning all parts are compatible. I installed Unicorn's low power rocket valve myself to make it field-legal and found it to be drop-in fit, so I can kind of confirm.
My question is, since I intend to use this mainly for fielding, are there any parts of the internal I need to be careful of for long term use? Thank you.
