THE ICONIC MK18 JUST GOT BETTER!

Lancer Tactical has added the classic MK18 to their Proline Series and its exactly what you need! As you know, the Lancer Tactical Proline Series features a full metal receiver set for a durable externals base. You get the new Delta Adjustable Stock for a very minimalist look with all the functionality you need. The MK18 Rail give you plenty of space for all of the accessories you want to increase your performance on the field! The MK18 Rail also provides a monolithic upper rail for your desired optics. Hit your targets with ease with the precision shots with the 6.03mm tight bore inner barrel preinstalled into the rifle. Change your FPS with ease, the quick change spring system allows you set up the velocity you need to play at different field limits. The true quick change spring system enables adjustment from CQB to outdoor and back through unlocking the mechanism secured inside the buffer tube.

The Lancer Tactical Proline series come with a fast trigger that is modeled after a bladed flat design. There is an ETU and MOSFET located in the gearbox with less wiring to assist in amplify trigger response.

Product Information:
I got this to pair with or even rival my MGC4, as I plan on upgrading the internals. Straight out of the box, it actually is decent! it does well at a range and i was able to hit targets out a really good distance. but the gears really needed to be shimmed. right away i noticed the magazine well just sucks. Lancer... do better lol this is such a normal issue for you, the mag that came with had issues fitting in!? then my lancer fast mags have a hard time fitting as well. I purchased all new internals for the gearbox, as well as a new hopup wiwth a 6.02 363mm barrel that has been lapped and flat hopped! it will be nasty soon! can\'t wait to take it to the field still.
Really recommend this over the high priced replicas you see out there. at least for the mk18 model. honest opinion, The MGC4 is just a better option if you save just a bit more, but, not as good looking as the MK18. this is still a good option, especially for the metal external construction! love this thing 7/10

Pros:
Solid construction for the receiver and handguard
super comfortable to hold and use
great out of the box performance, though gen 3 would be better. still love the price and quality
CTR style stock is so nice looking and can fit all of my Lipos no issue. (Titan battery didn\'t fit for me)
easy to work on!

Cons:
The Magwell is so trash, struggles with elite force mags, lancer mags!? BAMF mags and even my G&G mags are a struggle.
Tamiya instead of deans... Really LT?
trigger response is lacking compared to other ETU systems.
the iron sights are flimsy...
the ctr stock as significant wobble.
doesn\'t have bolt catch for hop up adjustments... its 2025 LT
also the orange tip is glued/pinned into the barrel, making it a pain to slap a new muzzle device on there.
