[Set] MK11 Short Sportsline Semi-Automatic Rifle Replica [A&K] + 220rd Enhanced Grip Polymer Magazine for AR-10/SR25 - Black

I bought two of these.
The spring inside stuck after the second use on both mags, even though I was careful not to overfill, and used only BLS premium BBs.
Then, after trying to unstuck it by shaking one of the mags, the spring flew out and the mag disassembled itself as if the bolt and nut at the bottom were not placed and tightened properly. The other mag is still in stuck position as I didn't want to risk a spring in my eye bc of shaking.

Overall, the plastic seems fine, but the final assembly seems poor.

Just what I was looking for, wanted to get an SR25k and saw it on a discount, took a chance and it is good.
Hits consistent shots at 40m on a target smaller than the front of a plate carrier(0.40g BBs used). Feels sturdy and the weight isn’t too much even after adding attachments.

Only things I don’t like about it is the stock, doesn’t have a rubberized stock so it isn’t the best to shoulder but it’s an easy swap for any M4 fitting stock, and the front sight doesn’t stay in the upright position, it’s a bit flimsy, but obviously you are putting a scope on the gun so it doesn’t matter to me, but might to some.
Overall pretty satisfied with it and would recommend it, it is maneuverable enough to use inside a building, just make sure to practice.
