The UK Arms MK36 Rifle Spring Airsoft Gun is constructed from plastic that keeps the weight down but is not as durable as its high end metal counter part. The UK Arms Mk36 is operated by pulling the charging handle which cocks the spring for a single shot. The spring system used in this gun allows it to be very affordable, however it is not skirmishable. The UK Arms Mk36 has realistic features such as the side folding stock, carry handle, folding bipod, and magazine release. Despite the realistic features, the UK Arms MK36 leaves much to be desired in the authenticity department.
This gun is a low powered spring airsoft gun that is extremely affordable and non-upgradeable. Please keep in mind, this gun is not skirmish ready and will be easily out performed by most quality airsoft guns. This gun is non serviceable and does not come with a warranty of any kind. More then likely if you attempt to use a gun on a sanctioned field you will get decimated. This gun makes a great display piece but do not belong on the field. For 105$ more you could purchase a high quality, skirmish ready AEG such as the JG MK36C which you can see here,
JG MK36C Airsoft Gun ( Latest Edition )
As previously stated, this gun is not field ready due to its low performance. Although due to its realistic look and features, this gun is a great choice for use in film productions or as a great display piece. Please do not expect to be able to compete with high quality airsoft guns while using this low cost airsoft gun.
