Recently I was given the opportunity by IPMS USA to review Aires Messerschmitt Bf 109G Gun Barrels for the 1/48 Eduard 109G series of kits. One of the first things to notice with this product is the excellent presentation of the packaging with the sealed flap on the back of package to allow for easy access to parts.
The molding on the resin gun barrels is excellent and they come off of the resin block with little effort. You receive 2 sets in the packaging, one set is of the MG 151/20MM canon that was used on the Bf109G. The G series 109 was designed to accept a variety of field conversion sets that allowed the changes to be made in the field. These were numbered from R-1 to R-7 with the MG 151/20MM canon under each wing being labeled R-6. These barrels make a good addition to the Eduard 109G series although there is not much difference in the look of both the resin and the one provided in the kit.
