Disappointed

by -

The short version, this product was found lacking. It will not latch /secure magazines of any sort. Im sticking to a dedicated lower.

RETURNED

by -

I tried old, new, factory and aft mrk and not 1 magazine would stay locked in. I may have gotten a bad unit but I'll pass for now. Returned, I'll opt for a different brand next time. NOTE: Lowers used :Anderson and Matrix.

so far so good.

worked great w/a PSA upper. ETS mags were too tight, Magpul were snug & factory Glock mags fit just right. I was concern about the negative review but haven't noticed any damage to my mags after 2 range trips. I will update if I anything changes.

Easy to install, fit and finish appear excellent.

Received today. Fit and finish appears excellent. Have not test fired, but I installed and cycled in several AR lowers and it fed flawlessly in my upper. Hope to get it out this weekend, and update.

Ran like a clock

Picked one up on sale to try out.

<br>Ran flawlessly on all rounds ran through it. Perfect cycling, loading, extracting. Excellent.
<br>
<br>Magazines do not drop free and must be pulled out of the unit. Takes a few times to get used to the mag-release, but it is very workable where it is located. Basically grab magazine from rear (like a grip) index finger pulls release, pull out mag. Magazines insertion is actually more positive than my dedicated glock mag lowers.
<br>
<br>No LRBHO. Of course, neither my PSA or QC10 units with LRBHO actually hold the bolt open reliably so no loss really.
<br>
<br>If you don't have a dedicated small frame glock mag lower, here is another way to get in to the 9mm pistol caliber carbine game. If you've already got Glock mags, they will work in this adapter without modification (unlike the TorkMag which requires a mod to the magazine to use the standard AR magazine release).

Works Great!

Works well with my PSA lower and PSA 9mm upper. Easy to install and easy to load & eject magazine.

Great product!

I have 2 of them. The fit is snug, and the factory mags work great, while aftermarket mags are tight. No rattle, no movement. I like this block a lot!!

Too many issues

by

Issues with fit in numerous Mil-Spec AR receivers and damage caused to the Glock magazines used by sharp edges inside the magazine well and the Magazine catch will not allow me to recommend the Sylvan Arms 9mm Glock Conversion Block at this time. I had written a lengthy evaluation but the character size limit prevents me from posting it here. I have contacted Sylvan with these issues and will update this review if they address my concerns.
