Hi everybody!
I wanted to buy a 9mm(9X21 here) conversion for my PWS modern musket so i asked to a local gun shop who also build upper receivers and other gun parts. I asked for a classic conversion with magwell insert to use modified UZI magazines because i wanted to use the same lower for both 9mm and 223,they immediately told me that they don't recommend this type of conversion because the magazine inserts are absolutely unreliable specially after many rounds fired when the insert start to get loose...they suggested to buy one of their own assembled complete rifles with specific lower for glock 9mm magazines... Not convinced,i insisted to get a quotation for a classic upper with magwell insert and they proposed me an assembled upper with : Faxon arms 16" 4150 steel qpq nithride 1:10" barrel Their own brand phospate BCG also good for glock magazine specific lower Aero precision standard upper receiver SLR rifleworks magwell insert I thought to reject just their magwell adapter wich cost 170€ going for a cheaper PRO MAG i can find for about 70€. What do you think of these conversions?Are they really so unreliable?If not,does install and remove the magazine insert often can cause feed problems?What about this components configuration? Thank you and forgive my horrible english! |

9x21mm or 9x19mm NATO? Huge difference in ammo availability and cost.
Several quality lowers are available for 9mm AR15's that do not use the pinned in place magazine block. I would look at one from Rock River Arms or other sources before hiring someone to modify a standard AR15 5.56mm lower receiver. Colt factory 9mm lowers using the magazine block work fine and do not "loosen up" after being fired. Converted UZI magazines may not work 100% of the time. Brownell's or Colt brand always do. Metalform makes the good ones for both companies and would be your best choice for a 9mm magazine. |

OP is in Italy. 9x19mm is not available to him under Italian law. 9x21mm is loaded to the same OAL and same velocities, but won't chamber in 9x19mm chambers (ie, military issue guns). OP, lots of folks use the modified Uzi mags. Unless you replace the follower, the LRBHO won't work. Lots of different drop-in magwell blocks on the market, the best are probably made by Hahn. ProMag has an indifferent reputation, but might be worth it to try if you can return it if you have problems. |

I live in italy and,due to our local laws,9x19 is forbidden in pistols,although it's allowed in rifles nobody will buy a 9x19 carbine because here is full of 9x21 brasses on shooting ranges and it's the same caliber practically.
Anyway,i prefer to go with the magazine adapter because of 3 reasons,first i can use the same trigger group,buttstock etc of my 223(couldn't even imagine to buy a good expensive trigger group both for my 223 and 9mm),second because of the price,with a upper and magazine adapter i will spend about 600-700€ instead of 1600 for the complete rifle with specific lower,i don't know why there is so much difference...last but not least,here we have a limited n° of pistols and scary assault black rifles we can own but upper receivers and gun parts doesn't have n° limits.

I don't care about the hold open ?? Give the ProMag a shot, then. That mag block isn't listed on their website here in the States. Some have trouble w/ their magazines, of which they produce many different types. I have two different magazines by ProMag (1911, AR) and have had no problems w/ them. Mag blocks sometimes have to be adjusted just so to feed properly, which sounds like you can do. |
