I just picked mine up. I ordered the blem m-lok pistol. Mine is item 516446311, which has been removed from their site. I think it got replaced by a similar item with a slightly shorter handguard? My hardguard looks like it has 1 more picatinny slot than whats on the websiet now. I've got several blems from PSA in the past and this one is the first one that's actually looks blemished. Its not terrible, just a few scratches. Nothing a light coat of dirt won't hide.
Enlarged ejection hole and the BGC is engraved with 45acp so you know what kind of bullets to put in it.
This is how close my hardguard comes to the muzzle device. It has one of their handguards that mounts with 4 screws and has anti-rotation tabs. Some of the guns I have only have 2 screws and no anti-rotation tabs.
This is the ass-end.
It looks like they thought about staking the screws here, but I can't tell. If they did try to stake them, this is a terrible job. I'm not sure that it matters too much on a blowback gun. If they do ever come loose, reckon I'll send it in.
Here's the ass-end of the bolt carrier.
MY only concern with the gun is the magazine fitment. I tried the Glock mag it came with and a RWB 26 round mag. Both of them lock in and are fine side to side, but rock a good bit front to back. I didn't have a ruler handy, but I'd say the end of the magazine can rock close to 1cm front to back. Here's a picture of the gap in the magwell. As long as it shoots reliably, I don't care. The mags don't feel like they're going to fall out or anything.
I'll try to get out this weekend and shoot it and report back.
ETA -
I tried testing out how it feeds and cycles live ammo. I cycled about 10 rounds of FMJ ball ammo. It pulled the rounds off the magazine and fed them into the chamber fine. It was pretty difficult to pull the charging handle to eject the rounds. Hoping it loosens up a bit after a few mags.
