In my last post, I went over the options I considered for the brace on my HK SP5K. In this post, I’ll review the three handguards I looked at – the original forearm, a US-made polymer unit with an integral hand stop and a low-profile aluminum unit.
I really have two places I shop for HK and related parts – HKparts.net and RobertRTG. So I went and checked out what they had plus I did google searches on “SP5K photos” and “MP5K photos” to see what others were using. I’m a visual guy and can scan a ton of photos very fast and then click to read the articles.
Removing the handguard is pretty much like all other HKs – pop the pin and pull down. You can see just how short that barrel is due to HK having to comply with German export laws for the pistol to be deemed “sporting purpose.” This also means you need to carefully think how to keep your fingers, notably your thumb, out of the way. You could argue training and holding the mag well but… there is a risk no matter what.
After researching for a bit, I got it down to the following three options that I could afford to try out:
Option 1: The Original Forearm
The unit that comes with the SP5K has two things going for it – the hand stop and the muzzle guard. The little indentations you see on the sides are actually thumb rests. From a safety perspective, this seemed like the best but I wasn’t sure about how the muzzle protector would hold up over time.
Option 2: A US-made Polymer Handguard Sold by HKParts.net
The second option I decided to try was a US made “Reverse stretch forearm with hand stop” that was made for HKparts.net. It was very well, fit my SP5K great and had great room for my hand but the problem was my thumb. It wanted to go in front of the muzzle.
To be clear, it is an excellent handguard. I blame the German politicians for the abrupt barrel. If I had a muzzle device out front, this would have made an excellent forearm.
Option 3: HKParts.net’s Own Low-Profile M-Lok Unit
So this brings us to the last option. I tend to like the flexibility that rails bring and decided to try another HKParts.net model – their Low Profile Forearm M-LOK. I ordered an Ergo hand stop/barricade stop to mount on it as well.
Bottom line, this just was not going to work as much as I wanted it to. Blasted politicians.
So What Did I Do?
After trying all three out, I decided to actually stay with the original forearm. Some day in the future, I will spend the money to have a B&T barrel installed with a tri-lug adapter. I really like the B&T brake that I run on my POF-5 and will then decide on which of the handguards I want to use. So, the brace and handguard were both selected, in the next blog post, I’ll discuss the optic I went with and why.
