KWA LM4 RIS PTR and KR7 Full Metal GBB Airsoft Rifle Field Test Review
If you haven’t already watched my Table Top Review Video for the KWA LM4 RIS PTR and LM4 KR7 Full Metal GBB Airsoft Rifles then make sure to do so for Specifications, Pros & Cons and close up video of both the KWA LM4 RIS PTR and KR7 Full Metal GBB Airsoft Rifles.
In this Field Test Shooting Review I only test out the KWA LM4 RIS PTR GBB Airsoft Rifle since both the RIS and KR7 are virtually identical in terms of their build and internal components, the KR7 has a a slightly shorter barrel but both KWA Airsoft AR M4 Rifles should perform very similarly.
To begin this Field Test Shooting Review of the KWA LM4 RIS PTR GBB Airsoft Rifle I first place 5 shots through my Chronograph using .20 gram plastic Airsoft BB’s and a full mag filled with propane gas. The rounds varied anywhere from around 330-360 fps but averaged a nice 345 fps which is perfect for most Airsoft games.
Next I placed a fresh paper target 30 feet away in my Indoor Sea Can Airgun Range. I then proceeded to shoot 10 shots in semi auto to see how accurate the KWA LM4 RIS PTR GBB Airsoft Rifle would perform for me. I am not a big fan of the aperture or peep sights found on most AR rifles, sure they work well for quick target acquisition but in terms of accuracy at least for me I find them hard to look through. Even so I was able to get about a 4 inch grouping with the KWA LM4 RIS PTR GBB Airsoft Rifle. I am pretty sure I could tighten this up with some more practice using these types of sights so user influence was involved here.
Of course I also had to place the KWA LM4 RIS PTR GBB Airsoft Rifle in Full Auto mode and do first a mag dump of the remaining 25 rounds and then I switched up the magazine for a fresh 40 rounder and did some shorter bursts again followed by a mag dump. The KWA LM4 RIS PTR GBB Airsoft Rifle performed flawlessly even in this somewhat cooler environment (17 degrees Celsius - 62 degrees Fahrenheit).
the KWA LM4 RIS PTR and LM4 KR7 Full Metal GBB Airsoft Rifles are fantastic performers, it’s hard to find consistent Gas Blowback Full Auto guns that can truly get through an entire mag without some sort of major cool down effecting their performance. In my testing even at the end of a full auto magazine the cycle rate was still high and there was no problem at all getting all 40 rounds out. If you want one of the highest quality and best performing Gas Blowback AR M4 styled Airsoft rifles then look no further!
