Thus, weight and size were saved by eliminating the Picatinny slots along the full length of the 9, 3, and 6 o’clock positions.Īdding Picatinny rail adapters onto a handguard to attach handguard accessories is less than ideal (more parts, adds gear height). The reasoning behind the trend to move away from quad-rails is because quad-railed handguards are inherently thicker, especially when the operator installs handguard covers on the rails to cover the unused slots for better reaction hand grip. Proprietary Picatinny slotted rail adapters for a Geissele SMR MK3. The Geissele SMR MK3 on my 18″ SPR build is one such example. Instead of having Picatinny slots along the full length of the rail on all four sides (12 o’clock, 3 o’clock, 6 o’clock, and 9 o’clock), the handguard will only have Picatinny slots on the top, with small Picatinny rail adapters that can be installed by the operator on the desired side of the handguard to allow attachment of a grip, flashlight mount, etc.

Many handguard manufacturers have been producing non-quad rail handguards as of late. Created by VLTOR, this was meant to offer a standard for rail accessory attachments that improves upon the Picatinny M IL-STD-1913 slot design.

The KMR is a free floating railed handguard that utilizes the KeyMod universal interface system. It will still shoot fine and you won’t be in danger of spinning jackets off in mid-flight.īut the part that made this build on par with current trends is the BCM 13″ KeyMod Rail handguard. 1:7″ is not too fast to shoot 55gr like USGI M193 ammo. 75gr and 77gr BTHP bullets are the way to go for accuracy and performance in the AR when magazine length ammo is the limitation. I like to be able to shoot the heavier weight bullets. People often ask me why I always use 1:7″ twist barrels for the AR. I figured an FN made barrel would be a quality barrel since FN is the primary small arms manufacturer for the US military (FN is contracted to produce firearms such as the M16/M4, M240, M249, and even the venerable M2. I was going to get a Daniel Defense barrel, but when I saw Brownell’s carried FN barrels (manufactured for Spikes Tactical) in a 16″ mid-length configuration, I went that route. But CHF with chrome lining will offer longevity with hard use. I love stainless steel barrels for their inherent accuracy (easier to cut quality rifling in stainless steel). Instead of going with a stainless steel 16″ barrel from White Oak, I decided to go with a cold hammer forged (CHF) barrel because I wanted something that would handle strenuous and continuous firing (heat). Mid-length gas systems are definitely the popular option for 16″ barrels because it was found that mid-length gas systems on the 16″ barrel length offered the best recoil / cyclical behavior without worrying about buffer weight. So I definitely wanted a 16″ build that was more in-line with current trends. Of course, this was back before railed handguards and flat top upper receivers became the rage. My old Colt Sporter Lightweight was a solid gun for its time (mid to late 90’s) with a lightweight 16″ carbine barrel, fixed A2 carry handle upper, which was outfitted with an Aimpoint CompM2 4MOA on a forward carry handle mount. I was going to use an existing Colt lower, but decided to go with some different furniture:

It was all downhill from there and I acquired the following parts to put together a 16″ upper: But with the high demand of firearms and related parts and accessories, the Larue upper was backordered for the unforeseeable future.ĭuring the latter part of 2013 into early 2014, I eventually started to put together and completed an 18″ SPR-style AR-15, which caused me to cancel my order for the Larue upper.īut after I got the SPR built, my desire for a 16″ rifle was rekindled when I picked up another VLTOR MUR-1A upper receiver for a good price from Midway USA. In early 2013, I got the impulse to add an updated 16″ carbine to my collection, so I ordered a Larue Tactical 16″ Stealth complete upper because I wasn’t in the mood to piece one together from parts.
