Solid kit. Very nice fit to an Anderson lower. Was surprised and impressed with how nice it is for the price!

Same here standard Anderson lower. Kit went together great. Runs awesome and have purchased 3 other kits since.

I love this gun. One of many that I have purchased. I installed an adjustable gas block, and it shoots so nice.

Jack Chambers –
quality parts. This is my first AR build from scratch.
everything fit great. Installed it in an Andersons lower.
went together smoothly and tight.
didn’t have to force any parts.
looking forward to building more kits from Durkin Tactical.

Nice kit I love the fact that it’s a complete build kit and priced accordingly. You are not lured in with a $200 build kit and then have to pat $65 for a lower parts kit and $100 for a BCG . The upper came with the forward assist, dust cover already assembled

Most of the parts are pretty good but I do have an issue with the Handguard. Instead of a Key-Mod or M-Lok it came with a Quad-Rail which is not anything but a Quad-Rail. As Quad-Rails go it isn’t bad looking BUT, if you want to mount an optic that that will keep the rail and upper receiver lined up then you are screwed. These rails are NOT Mil-Spec. I tried to mount my Vortex Strike Fire red dot in front of a Magpul pop-up sight and not happening. The Picatinny on the handguard is not cut to keep the slots all at the Mil-Spec spacing so I have to either mount the red dot back up almost against the pop-up or on the rail. Since the rail does not have any centering tabs it would have been nice to use the red dot base to keep things straight and aligned. The first Picatinny tad on the rail is too long by 1/10th. of an inch. Doesn’t sound like much but it still keeps this setup from being Mil-Spec. So, I like most of the items but I don’t like the non Mil-Specs of the rail. It screwed up my sighting idea.
