The military A2 variant has these scales thicke- ned but it seems that some rubber will be a far better solution. Safety switch: Nothing surprising here. The standard am- bidextrous safety switches are not super-comfy but they can be easily replaced. I've switched them for a custom DEFTAR safety switch with asymmetric levers. The safety switch pull might be adjusted with a single screw inside the lower receiver Trigger group: The most serious flaw of first production batches of MSBS/GROT were incompatible with AR-style trigger groups. It might be done yet it requires some armorer skills and some DIY work inside the trigger. This is crucial for firearms safety so we don't recommend it. Trig- ger is typical MIL-SPEC czyli tak sobie (troszkę gumowaty, z wyraźnym oporem i punktem prze- łamania, umiarkowanie długim resetem i wy- raźnym kliknięciem po resecie). Not so bad and enough for quick shooting but if you want to use it in a shooting championship you will be disap- pointed as it is a military-style rifle converted to semi-automatic. Trigger was a reason for the replacement of the lower receiver in our gun which was also a reason why the initial release of the rifle for the commercial sales was postponed. After around 150 rounds fired the trigger started to "freeze" when it was slowly squeezed and released after a single shot. It didn't happen during quick sho- oting. Same situation happened in one of the three "shooting magazine demo" rifles and the company finally decided to improve the lowers. stock adapter (buffer tube is required) now available for purchase. IN USE My feedback is based on 30 months of constant use. Upper and lower fitting: Definitely MSBS/GROT can't be compared with JP or similar rifles. There is some play between upper and lower receivers which at the first glance might look like wobbling stock since it might be felt when you move around the pistol grip. It is not significant but noticeable and some shooters may simply don't like it. Coatings: that's the bad thing here. Finishing coating on stainless steel parts is right but the anodizing on aluminium parts should be improved. There is no excessive wear of coatings on the steel parts - check the photos of all three rifles. There is some wear on the bolt carrier and signs of over tightened screws (brass deflector and plug). They can be easily over- tightened and their ends will scuff the bolt carrier inside the upper receiver. The brass deflector and plug are quite soft. Anodizing is poorly executed, especially on the handguard. The anodizing of the upper receiver is better and there are just some sli- ght wear marks on it. Handguard has visible signs of use and it gets easily scratched and dinged. The extended handguard seems to have better anodizing but it wasn't checked in use yet. Anodizing should be definitely improved. Accuracy: MOA and even sub-MOA accuracy on 100 meters distance wasn't anything unusual for a 16" barrel. The shorter barrel wasn't so accurate but it also tends to "prefer" the heavier rounds due the differen- ce in barrel twist (1:9 in 10.5" vs. 1:7 in 16"). Side note: in our rifle zeroed on 100 meters with 10.5" barrel after the barrel swap, the POI moved around 25 cm to the right (triple checked). Ergonomics: Ergonomics of the rifle are almost perfect for me. I had no problems with transition from the AR platform bolt release system to MSBS one. In my opinion GROT is far more ergonomic and does not require additional accessories as BAD Lever. The charging handle is also far more convenient than the T-shaped charging handle in the rear - in most of the "race guns" there are additional side charging han- dles too. In our GROT there were no problems with the charging handle and nothing fell off. The plastic scales can possibly break when they will hit the hard surface as the attachment pin will act as a wedge. www.fragoutmag.com
